Function Tutorial - Locations and MappingThe 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 thedata, 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 systemThe 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 ‘AllowEditing’ icon (make sure the icon goes red).Make the Coordinate_System column wider, so you cansee all the values in the drop-down, and from the Drop-Down select “WGS_84” (these co-ordinates arelatitude/longitude, and most latitude/longitude coordinatesuse the WGS_84 system).EarthScience Information Systems Pty LtdEmail: Support@ESDAT.com Web: www.esdat.net Page 5
BasemapsFunction Tutorial - Locations and MappingExercise 3: Adding a vector basemapTo 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 layercan 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 themost versatile for drawing. After saving the file the layer will be added to the Map Layers (onthe right), but will be empty.To edit this layer click the Pencil icon in the toolbar immediately underneath the layertoolbar. 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 propertiesDouble click the layer to change the properties – the example shows the options tochange the Basemap layer.EarthScience Information Systems Pty LtdEmail: Support@ESDAT.com Web: www.esdat.net Page 6
