Geospatial Modeling

The popularity of the internet, the ever-present mobilephone and the prevalence of location-based services haveresulted in almost everyone interacting with location-basedinformation in some form in their daily lives. It has alsobecome critical for governments and organizations toembrace this type of information as part of strategic decisionmaking. Geospatial information can be modeled inEnterprise Architect and also integrated with other data toform a single and comprehensive view of information notpossible in other tools.

Enterprise Architect, through the use of MDG Technologies,supports the Geography Markup Language (GML)application schemas and the modeling of ArcGISgeodatabases. The information precursors to these models -such as community conceptual models - can also bemodeled, and traceability can be used to connect the modelstogether.

GeographyMarkup

Language

MDG Technology for GML is theimplementation of the Open GeospatialConsortium's Geography MarkupLanguage (GML) 3.3 for EnterpriseArchitect, which provides an XMLgrammar for geographical featuremodeling capabilities within EnterpriseArchitect



Getting Started

Enterprise Architect partitions the tools extensive featuresinto perspectives this ensures that you can focus on aspecific task and work with the tools you need without thedistraction of other features. To work with the ArcGISGeodatabases or Geography Markup Language features youfirst need to select the following perspectives:

Database Engineering > ArcGIS

Information Exchange > Geographic GML

Setting the perspective ensures that the ArcGISGeodatabases and Geography Markup Language diagramsand their tool boxes and other features of the perspectivewill be available by default.

ArcGIS Geodatabases

Using the ArcGIS features in Enterprise Architect you canvisualize geodatabases inside this powerful system andcollaboration platform. This allows you to unify teamsworking in traditional software centric and engineeringsystems with your geospatial teams defining features anddomains. Teams defining the strategy business rules andrequirements for a system or the components that deliver the



system functionality can share models with the geospatialteams creating an integrated model that will help withintegration and risk reduction.

Geography Markup Language (GML)

Using the Geography Markup Language (GML) facility youcan model organization or community based applicationschemas. The models can be used to show the relationshipbetween Features and these elements in turn can contain anynumber of Properties that qualify their characteristics. Thesecan be based on defined Types, DataTypes, CodeLIsts orEnumerations.



ArcGIS Geodatabases

Exchange, Model and Visualize ArcGIS Geodatabases

Enterprise Architect allows you to import and exportArcGIS geodatabses allowing you to visualize Features andDomains within this powerful collaboration platform. In therecent past there has been a separation of the disciplines ofsystem and software development and geospatialdevelopment. In this age of social architecture and digitaldisruption almost every project and endeavor requires someaspect of location information from simple delivery servicesto agricultural, mining, exploration, weather, real estate anddisaster recovery systems.

The ArcGIS system, developed by Esri, supports thedevelopment and management of geodatabases. As it is forother databases, it is useful to model the design of a



geodatabase using a standard notation such as UML. Youcan perform such modeling in Enterprise Architect, usingthe UML profile for ArcGIS, which is part of the built-inMDG Technology for ArcGIS. Once you have modeled anArcGIS schema in Enterprise Architect, you can export themodel to ArcGIS as an XML Workspace document. Youcan also visualize an existing ArcGIS geodatabase schema,by importing the ArcGIS XML Workspace document intoEnterprise Architect.



Example Diagram

ArcGIS diagrams allow you to visualize the geographicfeatures, domains and other elements that make up ageodatabase schema. In this example a Building has beensub-typed as a house, the house in turn is sub-typed basedon the material type. The subtypes of the House references aCoded Value Domain also presented in the diagram withtwo Domain Code Values:

Brick·

WeatherBoard·

A Smart Meter is associated with the house. The House is atype of Building and the Building contains the property ofStreet Address



Exporting ArcGIS XML Workspaces

When you have modeled your Geodatabase WorkspaceXML Document (containing the ArcGIS schema), you canexport it to an external directory (using the Publish ModelPackage facility), from which you can then import it to theEsri ArcCatalog.

Access

Click on an ArcGIS stereotyped Package (your ArcGISWorkspace Package) in the Browser window.

Ribbon Specialize > Technologies > ArcGIS >Export to ArcGIS Workspace XML orPublish > Model Exchange > PublishAs...

ContextMenu

Right-click on Package | Specialize |ArcGIS | Export to ArcGIS WorkspaceXML

KeyboardShortcuts

Ctrl+Alt+E : Publish



Export the Workspace

Option Action

Root Package Display the name of the selected ArcGISWorkspace Package.

Filename Type in or browse for the file path intowhich the XML file is to be generated.

XML Type Select 'ArcGIS' as the XML/XMI versionto export the Package to.

Format XMLOutput

Format the output into readable XML(this takes a few more seconds at the endof the run).

Write LogFile

Write a log of the export activity(recommended).The log file is saved to the directory intowhich the XML file is exported.

View XML Click on this button to view the exportedXML file.

Export Click on this button to initiate the XMLexport.



Close Click on this button to close this dialog.

Progress Observe the progress of the XML export.

Notes

The MDG Technology for ArcGIS is available in the·Professional, Corporate, Unified and Ultimate Editions ofEnterprise Architect

In the Corporate, Unified and Ultimate Editions of·Enterprise Architect, if security is enabled you must have'Export XMI' permission to export to XML

Before exporting your model to an ArcGIS schema, you·must define at least one Spatial Reference element;Spatial Reference elements are referred to by otherschema elements via a dynamically linked Tagged Value,named SpatialReference

The DefaultSpatialReference tag on an ArcGIS Package is·used to specify a Spatial Reference that can be applied toall Feature Datasets and Feature Classes in the workspace;therefore, you do not need to apply a Spatial Referenceelement to each Feature Dataset or Feature Class

If you do not reference a Spatial Reference Class from·any Feature Dataset or Feature Class in your ArcGISmodel, Enterprise Architect by default will generate anXML schema with Unknown type of Spatial Reference



for these elements



Importing ArcGIS XML Workspaces

If you have a Geodatabase Workspace XML Document(containing the ArcGIS schema) you can import it into yourEnterprise Architect project as a UML model.

Before running the import, deselect the 'Sort FeaturesAlphabetically' checkbox on the 'Objects' page of thePreferences window (Start > Desktop > Preferences >Preferences). This ensures that the fields are imported andorganized in Enterprise Architect in the same order as in thesource.

Access

Click on the target Package in the Browser window.

Ribbon Publish > Technologies > Publish >ArcGIS > Import ArcGIS WorkspaceXML orPublish > Model Exchange >Import-XML > Import Package fromXML : Other XML Formats > ArcGIS

ContextMenu

Right-click on Package | Specialize |ArcGIS | Import ArcGIS WorkspaceXML

Geography Markup Language (GML)

Model Geographic Features and Generate ApplicationSchemas

You can create expressive and collaborative models of theimportant features in your domain and use these to generateGML compliant application schemas which can beconsumed by other applications. Many of the disruptiveforces and technologies that have changed the way weinteract with each other and the world we inhabit, involvegeographic locations and features. We drive along roads andstop at lookouts to view coastal features or cityscapes, wetravel abroad to view monuments and buildings such aschurches and museums, we rely on wind farms for energyand we take off and land at airports to name a few. You canmodel any geographic features of interest using EnterpriseArchitect's implementation of the Geography MarkupLanguage which is fundamental for geographic informationsystems as well as its use as an open interchange format forgeographic transactions on the Internet.

UML Classesfrom ISO

(Optional) You can download the UMLClasses implemented in ISO/TC 211 asan XMI file, then import the XMI fileinto Enterprise Architect as a Packagecontaining diagrams and standard UMLClasses, which you can reuse in yourmodel.

Not all UML Classes implemented in·ISO/TC 211 have a correspondingmapping in GML; the Classes that havea mapping (as specified in the GML3.2.1 specification) are specified in theconfigurable fileGMLClassMapping.xml in the 'SparxSystems > EA > Config > GML' folderThe Namespace information for these·Classes is specified in the configurablefile GMLNamespaces.xml in the 'SparxSystems > EA > Config > GML folder'

GMLApplicationSchemaGeneration

Any model you create using the built-inMDG Technology for GML can beexported as a GML Application Schema.Using the configurable fileGMLStereotypes.xml in the 'SparxSystems > EA > Config > GML' folder,you can specify aliases for the standardGML stereotypes. The GML ApplicationSchema Generator will also consider



these aliases during Schema generation.
