Start HereWelcome to GeoMedia Professionalthe next generation in geographic-information systems (GIS). Based on Jupiter technology from Intergraph Corporation, this product is an enterprise GIS for the Windows 2000, Windows XP, or later operating systems. This product is the perfect tool for collecting GIS data, populating an enterprise database, and turning information into precise finished maps for distribution and presentation. As a viewing and analysis tool, this product allows you to combine geographic data from different sources, in different formats, and with different map projections, all into a single environment. Using this software, you can perform complex queries on spatial and attribute data from various sources, and produce numerous views of highly sophisticated maps in a single GeoWorkspace. Furthermore, this product gives you the capability of printing those map views on a single sheet and adding borders, marginalia, and other finishing touches. As a data capture and maintenance tool, this product allows you to capture and to edit data more easily, faster, and with more intelligence than other products. Its integrated vector and raster snaps allow you to capture vector data from raster images, automatically identifying snap points to ensure accurate heads-up digitizing. The software also provides table-top digitizing and vector transformation for data requiring geometry transformation. Using the software, you can capture clean, accurate data the first time, thus minimizing editing. Automatic vector breaking and coincident geometry digitizing allow you to avoid traditional data-capture problems. However, you can locate data-capture problems with automatic error detection and then correct them with intelligent feature placement and editing tools. Furthermore, you can quickly annotate the data with powerful labeling and text-placement tools. This product is also a software-development environment, and you can customize it with standard Windows-development tools such as Microsoft Visual Basic and Visual C++.

Looking at GeoMedia Professional An Overview:The first thing you do in GeoMedia Professional is create a GeoWorkspace or open an existing one. After you open a GeoWorkspace, you configure it to suit your needs. You can, for example, change the coordinate-system properties or insert a map or raster image to use as a backdrop for geographic data. Your configuration is saved when you save the GeoWorkspace and restored when you reopen it. The data you view is stored in warehouses, and you access data by creating connections from the GeoWorkspace to one or more warehouses. The software presents a series of dialog boxes that prompt you for the information necessary to create the connection. Because data are not stored in the GeoWorkspace, all workflows require at least one warehouse connection. A warehouse stores both geometric (graphic) and attribute (nongraphic) information. For example, a parcel might be represented by an area geometry and defined by attribute information such as the owners name and the date it was purchased. Once you connect to at least one warehouse, you can display and analyze data from it. The software allows you to view multiple data sets from different warehouses in various formats in a single GeoWorkspace. This means you can perform spatial analyses on data from different sources in different formats using buffer zones, spatial queries, and thematic displays. In this product, features are contained in feature classes, and the word feature refers to each instance of a feature within a feature class. Feature classes, images, query results, and thematic displays in the map window are collectively referred to as either features or map objects. Features are represented in the map window by geometry and in the data window by attributes. You can display any number of map and data windows simultaneously or separately. They are linked so that changes made in one window are automatically reflected in the other. You display features in a map window by adding entries to the legend. The legend is the control center for the map window. Through the legend, you populate the contents of the map window and control the display characteristics of the features, including their style and display priority.

You can also perform tasks, such as capturing new data, performing maintenance on existing data, and inserting images or buffer zones. Furthermore, you can view data written to a read-write warehouse along with other data sets in a single GeoWorkspace. Results of your analyses can be customized in the map window, printed, and saved for future use, all without altering the original data.

1-7


This dialog box lets you create a new GeoWorkspace using a blank GeoWorkspace or a GeoWorkspace template or open an existing GeoWorkspace from a list of recently opened GeoWorkspaces. You can select one from the list, and click OK, or if the existing GeoWorkspace you want is not listed, you can select More Files, and click OK to find the GeoWorkspace yourself. To not open this dialog box when you start the software, check the Dont show this dialog box again check box. Note: To exit the software at any time, select File > Exit from the GeoMedia Professional menu. See the Working with GeoWorkspaces chapter for complete information on using GeoWorkspaces.

Getting Around in the SoftwareFamiliarity with Microsoft Windows conventions and Microsoft-Office applications should make it easy for you to get around in this product. As in Windows, for example, you move a window by placing the cursor over the title bar and dragging the window to a new location. Buttons and menu items are dimmed when the tools they invoke are not available, and you can see what tool a button invokes by placing your cursor over the button. Common tools, such as File > Print, work essentially the same as they do in any Windows application. Still, the GeoMedia Professional working environment does have some special characteristics: GeoMedia Professional offers several specialized toolbars that are available only under the appropriate circumstances. The Data toolbar, for example, is available only when the data window is active. Select View > Toolbars to specify which toolbars you want to display. Some right mouse menus are available in this product. You display right mouse menus by pressing the right mouse button. The tools on the menu vary with the location of your cursor. The products toolbars can be moved from their default locations and docked at other locations within the interface. Moving a toolbar over a map window converts the toolbar to a dockable control, and some tools provide a control rather than a dialog box interface. Further, clicking the right mouse button on the title bar of a control displays a menu that allows you to restore, move, minimize, maximize, or hide the control, while clicking the X icon dismisses the control. Clicking the right mouse button on a toolbar (or on the icons in a control) displays a menu that allows you to turn toolbars on and off, display the Status and Precision Coordinates toolbars, and customize toolbars.

Within the software, you work in three types of windows, map windows, data windows, and the layout window. These windows are contained in a GeoWorkspace, which is roughly analogous to a workbook in Microsoft Excel. If you have a Microsoft IntelliMouse, you can use it to manipulate map, data, and layout windows faster and more efficiently.

1

See the "Working with Map Windows," "Working with Data Windows," and Working with Layout Windows chapters for information on the three types of windows

Customizing the Menus and ToolbarsYou can customize the GeoMedia Professional working environment to display the menu items and buttons you want and to accept the keyboard shortcuts you specify. You can do this on a particular installation of your software by using the Customize command. In addition, you and/or your administrator can also use the Save Customized Settings and Load Customized Settings commands to save customized menus and toolbars to an XML document that can be placed and reused on other machines.

Using the Customize CommandThe Customize command (Tools > Customize) lets you customize menus, keyboard shortcuts, and toolbars to help you perform your tasks more efficiently, as follows: Keyboard shortcutsAssign shortcut keys to commands and remove them as well as restore all shortcut key assignments to the original settings. MenusAdd new menu items to and remove items from menus for quick access to the commands you use most often, and reset menus to the original settings. You can also add, rename, and delete menus. ToolbarsCreate new custom toolbars and add command buttons to delivered and custom toolbars. See the Using the Customize Command topic in the GeoMedia Professional Help for complete information on using this command.

Using the Save/Load Customized Settings CommandsOnce you have customized the menus and toolbars for map windows and data windows with the Customize command, the software provides an easy way to save (Save Customized Settings) and to recall (Load Customized Settings) the customized menu/toolbar configurations through a customized settings file (GeoMedia Customized Settings, .xml), including commands from the core products and add-on products, as well as custom commands. The layout window menus and toolbars, however, are not included in these customized settings. You can thus create custom interfaces for specific purposes or workflows as required. You may, for example, create a menu and toolbar configuration for an edit-only workflow. 1-9


To save a customized configuration, you select Tools > Save Customized Settings to open the Save As common dialog box. You then select the drive and folder for the new customized settings file; the default folder is \GeoWorkspaces. Next, you type an appropriate name for the customized settings file in the File name field, verify that the Save as type drop-down list displays Customized Settings File (*.xml), and then click OK. To load a saved customized settings file, which removes all current menus and toolbars and replaces them with the menus and toolbars defined in the XML document, the software provides the following three options: Load Customized Settings command, command line, and startup. The startup option is configured through the products automation layer. The last two options let you load your customized settings at the end of GeoMedia initialization. The schema for these documents is defined in GeoMedia Professional\Schemas\gmcustom.xsd. Note: A standard menus and toolbars customized settings file, \ProgramFiles\GeoMediaProfessional\ CustomizedSettings\StandardSettings.xml, is delivered with the software. You can use this file to restore the delivered default menu and toolbar settings. To load a customized settings file with the Load Customized Settings command, you select Tools > Load Customized Settings to open the Open common dialog box. You then select the drive and folder containing the customized settings file you want to load. Next, you type the name of the customized settings file in the File name field or select it from the list, and then click Open. The command line option is /custom . During GeoMedia initialization, this option is read, and the menus and toolbars are loaded, for example: GeoMedia.exe /custom D:\xmlfiles\MySettings.xml.

In GeoMedia Professional: Display the feature table in a data window. Sort the data window rows by a common identifier. Paste the attribute values from the paste buffer into the data window to populate the features.

3. Execute a Query/Update in the database to load the columns based on a common identifier, for example, a PIN.

Legacy GIS DataData in legacy systems, like Intergraphs MGE and ESRIs ARC/INFO and ArcView, already represent the graphic location (the map) and information (the database attributes supporting the location) for each item on a map. So, for a red line on a map that represents a U.S. Highway, the Department of Transportation may have database attributes that tell the resurfacing, accident, or bridge-maintenance records. One problem with systems like these is that they do not talk well to each other. GeoMedia Professional provides a platform where you can easily display and manipulate data from all three legacy systems. For an enterprise that wants to migrate part or all of their current GIS to GeoMedia Professional, the workflow uses Intergraphs powerful data-server technology combined with industry-standard databases. Operators can then add or edit data in the new environment.

Migrating Legacy GIS Data into GeoMedia Professional:1. Connect to the legacy data source (MGE, ArcView, or ARC/INFO). 2. Select the features to migrate.

3. Import the selected features into a read-write warehouse (Access, Oracle, or Oracle Spatial Cartridge). 4. Edit and add the GIS features in GeoMedia Professional. Note: You can import GIS data into any GeoMedia Professional-supported format into an Access or an Oracle warehouse. You can import an entire feature class or only those features meeting the conditions that you define with an attribute filter. When you import features, the software copies the data from the source warehouse to a target read-write warehouse.

What is a GIS?A GIS (geographic information system) is a computer system capable of assembling, storing, manipulating, analyzing, and displaying geographically referenced information. This system contains both data identified according to their locations and graphic and nongraphic data.

What Can I Do with a GIS ?A GIS allows you to perform the following functions: Locate information spatially for example, find a site by latitude and longitude or by proximity to other features. Visualize information more effectively and intuitively. Spatially analyze information from many integrated data sources. Graphically navigate through data sets, for example, drill downs. Answer questions more quickly and accurately. Plan work and activities more effectively. Save resources on construction, maintenance, management, surveying, and similar activities.

Aspects of a GISThe following are some important aspects of a GIS system: 1-16 A GIS knows where things are, which is essential to rational decision making in many cases. The a GIS is only as useful and accurate as the information you put into it.

Proper implementation of the technology is critical to the systems success A map itself is not a GIS; a map is a derived output product of a GIS. A map is to a GIS as a report is to a database.

Types of InformationA GIS may contain the following types of information: TextualReports, tabular data, and data streams. Image FilesAerial photos, scanned images, and photographs. CAD (Vector)Drawings containing linework, such as floor plans, schematics, and diagrams, which are sometimes drawn to scale and sometimes not. GIS (Smart Vectors)Maps, properly scaled and properly oriented, and support for multiple projections. Map feature definitions also include nongraphic data (attributes). Other DocumentsOffice automation: presentations, spreadsheets, web pages, and so forth.

GIS Concepts & TerminologyThe following are several important GIS concepts and terminology that are used when describing GeoMedia Professional. They are discussed at greater length in their respective parts of this document. WarehousesCollections of GIS data, for example Oracle, ARC/INFO, and CAD databases. GeoMedia Professional establishes connections to warehouses to gain access to the GIS information.

FeaturesFeatures are digital representations for real-world entities.

Features have attributes. A feature class definition defines all of the attributes and associated data types. Specific instances of the feature class have unique values for the attribute fields.

Features can represent almost anything.

1-18

Start Here

Features can be represented in the GIS as points, lines, polylines, areas, arcs, text, and images.

1

Features can be organized into categories, themes, or layers.

LegendsLegends control what information appears in a map window, including symbology, render order, and interactive characteristics.

Queries and Spatial QueriesQueries are questions, some complex, some simple, that you can pose to the GIS. For example, a simple query might be to see all cities with more than 100,000 people. Or, you may ask to see all states with a population over 100,000 containing cities where the total crime rate is greater than 125. Spatial queries supplement relational operators with spatial operators.

Coordinate Systems and ProjectionsMathematical transformations must take place to represent the Earth in two-dimensional space. It is the same source information in each case, just represented differently. This is the primary cause for data from disparate sources not to overlay properly. 1-19


Analytical CommandsComplex analyses and processing of the contents of the GIS.

GIS ApplicationsA GIS can be productively used in many endeavors, including the following: Agriculture Cartography Geology Education Facilities Management Asset Management Business Meteorology Tourism Archeology Military installation management Environmental Management

Utilities Management (water and sewer, electric, communication systems, cable, cell phone coverage areas, and so forth) Natural Resources and Resource Conservation Public Safety (emergency dispatch management) Disaster planning (hurricane evacuation, earthquake) Health Care Industry (disease outbreak studies, epidemics) Industrial (plants, pipelines, storage tanks, and so forth) Aeronautical (Airport GIS, airspace management) Marine Engineering (biology, soundings) State and local government Land Information Systems (LIS): parcels, right-of-way, and so forth. Transportation Industry (highways, railroads, planning and analysis)

Benefits of GISSome of the benefits of using a GIS are the following: Reduces Operations and Maintenance CostsAs a productivity multiplier, a GIS enables less-skilled personnel to complete sophisticated analyses, as well as expanding the output of the technical staff. Improves Mission EffectivenessA GIS provides command and management personnel with the opportunity to rapidly analyze multidisciplinary sets of data and to arrive at the best solution with complete supporting documentation. Provides Rapid Modeling Capabilities for Analyzing Alternative Strategies A GIS provides the capability for command personnel to make the best and most cost-effective decisions in tight budget environments. Greatly Improved Communication AidsEffective communication is essential for managing an infrastructure, whether it be a college campus, military installation, or a city. GIS visualization tools are fast and easy to use. Promotes HarmonyBy providing a standard set of data and tools for modeling and analysis, major alternatives for a project can be consistently produced and analyzed. This capability helps bring teams together with the increased job satisfaction associated with the feeling of effective group participation. Provides a Repository of Institutional KnowledgeBy incorporating as much knowledge as possible into standard GIS functions, the loss of key personnel knowledge can be minimized.

Working with GeoWorkspacesA GeoWorkspace is the container for all your work in this product. Within its confines are the warehouse connections to your data, map windows, data windows, layout windows, toolbars, coordinate-system information, and queries you have built. The first thing you do is open an existing GeoWorkspace or create a new one. Once you are in a GeoWorkspace, you can change its coordinate system, establish warehouse connections, run queries, display data, and perform spatial analyses. The settings and connections you define in a GeoWorkspace are saved in a .gws file, although the actual data remains stored in warehouses. The software is delivered with an example GeoWorkspace, USSampleData.gws. Note: The U.S. Sample Data Set contains a shaded relief image of the United States, complete with hypsometric tints. The data consist of a 1000-meter pixel resolution RGB GeoTIFF file. Every GeoWorkspace is built on a template, and you can create your own templates or use an existing one. The software is delivered with a default GeoWorkspace template, normal.gwt, which contains an empty map window, an empty legend, and a predefined coordinate system. If you accidentally delete the normal.gwt file, you must reinstall the software to restore the template; so it is a good idea to back up this file. This is a representative workflow for creating and configuring a GeoWorkspace: 1. Select File > New GeoWorkspace. 2. Select a template. 3. If the coordinate system you want differs from the one in the template, define a different coordinate system for the GeoWorkspace. 4. Make warehouse connections; configure map and data windows (topics covered in other chapters). 5. Save the GeoWorkspace.

2

2

Creating a GeoWorkspaceYou create a GeoWorkspace using normal.gwt or another template in the \GeoMedia Professional\Templates\GeoWorkspace folder. The available templates are displayed when you select File > New GeoWorkspace from the GeoMedia Professional menu or Create new GeoWorkspace using from the introductory GeoMedia Professional dialog box. 2-1


The software assigns a default title of GeoWorkspace1 to each new GeoWorkspace. When you save a GeoWorkspace, you assign it a filename, and the software automatically adds a .gws extension.

Opening a GeoWorkspaceYou can have only one GeoWorkspace open at a time. When you open a second GeoWorkspace in the same software session, the software closes the open GeoWorkspace. If the GeoWorkspace you want to open is read-only, you are advised that it is read-only and asked if you still want to open it. If you open it, the software makes a copy of the read-only GeoWorkspace and opens it as read-only. If you then make changes to this internally copied GeoWorkspace and try to save it, you are advised that you have made changes and asked if you want to save the GeoWorkspace to a different file name because the original GeoWorkspace is read-only. The changes you make to a read-only GeoWorkspace are discarded when you close it unless you save it with a different file name. A list of the most recently used GeoWorkspaces appears at the bottom of the File menu. You can open a GeoWorkspace from this list by clicking the filename. Note: GeoWorkspace (*.gws) files created in GeoMedia Professional and other GeoMedia applications that are saved to disk with queries specific to those applications, such as geometry validation queries, will not open in GeoMedia.

To open a GeoWorkspace:1. Select File > Open GeoWorkspace.

2-2

Working with GeoWorkspaces

2. Select the GeoWorkspace you want. 3. Click Open. Note: If a connection fails while attempting to open a GeoWorkspace, an error dialog box appears prompting you to verify that your warehouse connection parameters are correct.

Delaying Data LoadingDepending on your data, opening an existing GeoWorkspace may take a long time. The amount of time varies with the number of feature classes being loaded into displays, the amount of data per feature class, and the processing time of any queries. To improve performance, you can delay the loading of data by selecting the Do not load data when opening GeoWorkspace check box on the General tab of the Options dialog box (Tools > Options). If this check box is not selected, which is the default, the software loads all data when opening a GeoWorkspace.

2

Upon setting this option, the map windows and data windows are empty when you open a GeoWorkspace. The legend entries in the map view are created but not in a loaded state; the data view shows a title but displays no records. Any existing queries are not reexecuted. Also, any subsequent opening of an existing GeoWorkspace, in the same session or future sessions, does not load the data. After opening a GeoWorkspace, you can selectively load its data as follows: Legend Entries Select View > Update All to update all legend entries in all map windows and all data windows. 2-3


Select one or more legend entries, display the right mouse menu (on the legend, not the map window), and select Load Data. This is enabled only when one or more of the selected legend entries is in an unloaded state. Select View > Update All to update all legend entries in all map windows and all data windows. Display the right mouse menu, and select Load Data. This is enabled only when the data window is in an unloaded state.

Data Windows

Automatically Backing Up GeoWorkspacesTo protect you against data loss due to GeoWorkspace corruption, the software contains an automatic backup function. This automated backup is performed immediately after a GeoWorkspace has been successfully read, at which point it is known that the GeoWorkspace is not corrupted and a copy can be safely saved. This backup is performed only if the GeoWorkspace itself is read-write, as there is no danger of a file corruption if it is read-only. Furthermore, the GeoWorkspace may be read-only because it is in a readonly folder or on a read-only medium (for example, a CD), which would prohibit creation of the backup in any case. The backup copy of the GeoWorkspace is made using a file copy, which ensures the backup copy is identical to the original GeoWorkspace except for the filename. The backup file has the same path and filename as the original GeoWorkspace except that the extension is .bak. If a former backup file by the same name already exists, it will be overwritten. The default is to automatically back up GeoWorkspaces, but you can turn this feature off by unchecking the Create backup when opening GeoWorkspace check box on the General tab of the Options dialog box (Tools > Options).

Saving, Closing, and Copying a GeoWorkspaceIn addition to saving GeoWorkspaces automatically through the backup function, there are several ways to save or to close one. When you save or copy a GeoWorkspace, you are saving all its settingsthe window configuration, the coordinate system, queries, legends, thematic displays, and warehouse connectionseven if you are connected to a read-only warehouse. The default location for GeoWorkspaces is specified during installation, usually the \GeoWorkspaces folder of your root folder. You can change the default folder through the File Locations tab of the Options dialog box. The default file extension for GeoWorkspaces is .gws. To save changes to a GeoWorkspace any time during a session, select File > Save GeoWorkspace. This saves but does not close the GeoWorkspace.

2-4


To save a new GeoWorkspace, select File > Save GeoWorkspace As, and type a name for the GeoWorkspace in the File name field. Note: To make a GeoWorkspace read-only, you use standard Windows procedures for changing file attributes.

To copy the open GeoWorkspace to a new file, select File > Save GeoWorkspace As, and give the GeoWorkspace a different name. This closes the open GeoWorkspace without saving changes to it since the session was opened or since the last save. The newly named GeoWorkspace becomes the open one. To close a GeoWorkspace without saving changes made since the last save or since the current session was opened, select File > Close GeoWorkspace.

2

To change the location of your GeoWorkspace files:The default storage location of your GeoWorkspace files is established when the software is installed, but you can change it from the File Locations tab of the Options dialog box.

E-Mailing a GeoWorkspaceWhen you select File > Send from the GeoMedia Professional menu, the electronic-mail application on your system starts and attaches a copy of the open GeoWorkspace. Because all warehouse connections are stored as folder paths, the person receiving the GeoWorkspace will be able to open the GeoWorkspace, re-establish all original warehouse connections, and view the data as it appeared when you e-mailed the GeoWorkspace. 2-5


1. Select File > Send. 2. Fill in the To and Subject fields as you would for any e-mail message. 3. Send the message.

Creating a GeoWorkspace TemplateThe default location for GeoWorkspace templates is \Program Files\GeoMedia Professional\Templates\GeoWorkspaces. You can specify a different folder through Tools > Options > File Locations.

To create a GeoWorkspace template:1. Select File > New GeoWorkspace. 2. On the GeoWorkspace Template dialog box, select the Template option. 3. Select the normal.gwt template, and click New. 4. Define the GeoWorkspace coordinate system (View > GeoWorkspace Coordinate System). 5. Make the warehouse connections you want for this template (Warehouse > New Connection). 6. Turn on and positionor turn offthe legend, north arrow, and scale bar (View menu). 7. Adjust the size and locations of the map and data windows. 8. In the map window, display the features and background images you want. 9. Build the queries you want saved with the template. 10. Select File > Save GeoWorkspace As. Note: If you have named an alternate file location for GeoWorkspace templates, that location appears in the Save in field of the Save GeoWorkspace As dialog box. Then if you want to store the new template in the main templates folder, click the drop-down arrow and browse to the \Program Files \GeoMedia Professional\Templates\GeoWorkspaces folder. 11. Verify that GeoWorkspace Template appears in the Save as type field. 12. Type a name for the template in the File name text box. The file extension must be .gwt. 13. Click Save.

Linking and Embedding a GeoWorkspaceGeoMedia Professional can act as an OLE server, which means you can insert a GeoWorkspace as an object into a container application that supports OLE. All such applications have an Insert Object command, or something equivalent, that lets you link or embed objects. You can also embed a GeoWorkspace by dragging and dropping the .gws file name from Windows Explorer into a container application. Only one view in a link can be active, and the container application shows the active view by default when you link a GeoWorkspace. However, in some container applications, you can edit the link and change the item part of the link source to a named view, which is the title on a map or data window (by default, MapWindow1 or DataWindow1, for example). When you embed a GeoWorkspace, the entire GeoWorkspace is embedded, not just a single map or data window, although you can see only the active view of the embedded GeoWorkspace in the document of the container document. The embedded GeoWorkspace can be edited in one of two ways. First, you can in-place activate GeoMedia Professional within the container application. When you do this, the container application displays its own File and Windows menus, but all other menus and tools belong to GeoMedia Professional. Clicking outside the embedded GeoWorkspace takes you back to the container document. Second, you can open the embedded document in a separate GeoMedia Professional window. This allows access to the other windows in the embedded GeoWorkspace.

Working with Coordinate SystemsThis application displays all dataeven data from different sourcesusing the coordinate system defined for the GeoWorkspace. Each feature class stored in a warehouse can have its own unique coordinate system and is transformed on the fly into the GeoWorkspace coordinate system when you display them in the map window. IMPORTANT: To accurately display raster images, FRAMME data, or data from many non-Intergraph proprietary formats in a GeoWorkspace, the coordinate system of the GeoWorkspace must either match that of the feature data in the warehouse or you must define a coordinate system file for the feature data so that it can be correctly converted for you. Assigning a coordinate system to your source data is the only way to ensure that GeoMedia Professional understands the source projection of your data. Data servers that use coordinate system files typically specify the association of feature name to coordinate system file in their ini file. In some cases these data servers allow the same coordinate system file to be shared by all features in the warehouse. To create a coordinate system file (*.csf), you use the Define Coordinate System File utility that is delivered with the software. A common method to create the .ini file is the Define Warehouse Configuration File utility. See "Displaying Data That Has No Coordinate System Specified" in this chapter. Also, see the Define Coordinate System File utilitys online Help. A coordinate system provides the mathematical basis for relating the features in your study area to their real-world positions. The software supports the following types of coordinate systems: A geographic coordinate system (the default) references a spheroid, expressing coordinates as longitude, latitude, where longitude is the angular distance from a prime meridian, and latitude is the angular distance from the equator. A projected coordinate system references a projection plane that has a well-know relationship to a spheroid, expressing coordinates as X,Y, where X normally points east on the plane of the map, and Y points north at the point chosen for the origin of the map. The X coordinate is called easting, and the Y coordinate is called northing.

3

3-1


A geocentric coordinate system references an earth-centered Cartesian system, expressing coordinates as defining the position of a specific point with respect to the center of the earth. These coordinates are Cartesian (X, Y, Z) where the X axis of the geocentric system passes through the intersection of the prime meridian and the equator, the Y axis passes through the intersection of the equator with 90 degrees East, and the Z axis corresponds with the earths polar axis. The X and Y axes are positive pointing outwards, while the Z axis is positive towards the North Pole.

Geographic and projected coordinate systems reference horizontal position using either longitude, latitude, or X,Y. Such a position may be extended to reference a vertical position in the form of a third coordinate that indicates elevation above a known reference. All GeoMedia coordinate systems provide both horizontal and vertical reference information. Coordinates may be transformed between these the geographic, projected, and geocentric reference spaces. A paper reference space, which is a scaled representation of the projection plane, is also supported. Because the shape of the earth's surface varies from one geographic area to another, the software interprets horizontal coordinates with reference to a network of geodetic control points called the geodetic datum. The horizontal geodetic datum in turn defines the reference ellipsoid, which is the model used to represent the shape of the earths surface. Vertical coordinates (elevations) are interpreted with reference to a network of vertical control or other vertical reference frame called the vertical datum. See the Co
