Summary

This tutorial will examine using location data in bulk (ie from a surveyor), basemaps, importing locations through the map panel, and use of the mapping features and tools. It will also cover labelling options.

The tutorial can be completed using either the Access and SQL versions of ESdat.

Pre-requisites

Tutorial 1 and the Function Tutorial Importing and Editing Data should all be completed before you begin this tutorial.

Function Tutorial - Locations and Mapping

EarthScience Information Systems Pty Ltd

Introduction Most site data entered into ESdat needs to be associated with a Location via specification of a

Location Code. By assigning a Location Code to any data, the information in the Location

table for that Location Code (coordinates and other information) will also be associated.

Wells (Piezometers), Chemistry Samples, Groundwater Levels, and many other kinds of data

have the facility to store a Location Code (or LocCode), which will always match a LocCode

value in the Locations Table.

The relationship between location codes and other information held in ESdat is shown below.

Location Codes in the Location Table may be automatically generated in some cases, if certain

choices are made in the import process. If a user is attempting to import Chemistry Samples or

other data using a Location not previously entered they will initially be unable to do so.

However if they then select Create Missing Parent Records a Location entry will be added. All

other Location information such as co-ordinates will then need to be added to that location later.

Importing and editing locations and co-ordinates We are going to import some new Location data into a new database. It is assumed you are

able to set up a new database in ESdat, if not see

http://www.esdat.net/esdathelp/index.html?tutorials.htm

ESdat allows location data to be added either in Bulk (ie data supplied from a surveyor) or by adding directly onto the Map in ESdat. Bulk import is covered below, and adding to a map is covered later, once we have a basemap generated.

We want to add new locations to a new ESdat Site/Project. The information about the location is as follows:

x Y

BH1 153.556756 -28.86857486

BH2 153.5568892 -28.86848345

BH3 153.5560937 -28.86837448

BH4 153.5564424 -28.86842897

BH5 153.5559023 -28.86846963

Exercise 1: Bulk Import using Import templates Create a new, blank, ESdat Site/Project to import this data into.

Click on the Import view type.

From the Blank Import Templates area, select Locations, and copy the above data into the Blank Import Template.

Click the Import button (Under the Add Ins button on the Custom tool bar), and select the Import button to import the new data.

The cells will now be shaded light green to indicate the data was successfully imported.

Click on the Close button.

In ESdat, go back to the Data panel and reclick on the Locations button to refresh the data, and to confirm that the data is present.

This approach can also be used to Update or Overwrite existing Location data in the database,

using the generic Import Template functionality described in the Importing and Editing Tutorial.

Exercise 2: Specifying the co-ordinate system The coordinate system for the data in ESdat is specified in the Project table (Access Version)(or

Site table (SQL Server versions). Using the new ESdat Site/Project we have previously created

(Exercise 1) complete the following:

Hover the mouse over the Data Tables button (top right)

Click on the Project table (Access Version)(or Site table (SQL Server versions)

Information about the Site/Project will now be displayed; note the Coordinate System for this dataset is blank (unless you specified it on project setup).

Put ESdat into Edit mode by clicking on the Allow Editing icon (make sure the icon goes red).

Make the Coordinate_System column wider, so you can see all the values in the drop-down, and from the Drop-Down select WGS_84 (these co-ordinates are latitude/longitude, and most latitude/longitude co-ordinates use the WGS_84 system).

Basemaps

Exercise 3: Adding a vector basemap To add a basemap:

Select the Location Data-Type button, and click on the Map panel.

A basemap layer can be added in most common GIS formats (the Add button) or a new layer

can be drawn in ESdat. We will draw our own, new site boundary.

Click the New button (pointer 1 on the image below).

You will be prompted to save this layer as a file (save it as test.dxf). The DXF format is the

most versatile for drawing. After saving the file the layer will be added to the Map Layers (on

the right), but will be empty.

To edit this layer click the Pencil icon in the toolbar immediately underneath the layer toolbar. On doing that the toolbar will change as shown below (pointer 2b).

Click Add Polygon (2b)

Draw a line around the outside of the points on the map (3)

Click Save (4)

Exercise 4: Changing layer display properties Double click the layer to change the properties the example shows the options to

change the Basemap layer.

Select the Area tab, and the Outline Sub-tab.

Change the Color to Red and click OK. The outline of the areas in the layer will be shown in red.

Try changing some of the other options here and note the changes.

For more information on base maps, see http://www.esdat.net/esdathelp/index.html?adding_basemaps.htm

Basemap Coordinate Systems If the coordinate system of the data in ESdat isnt specified, then all GIS Layers must be in the

same coordinate system as the ESdat data. However, ESdat has the ability to overlay d
