Viewing and Editing GIS Layer Data
InfoWorks ICM allows you to view and edit data in additional GIS layers that have been loaded onto the GeoPlan Window. InfoWorks ICM can only display spatial information - points and polygons - on the GeoPlan. However, the GIS layer may contain far more details about the point or polygon.
This functionality does not apply to Web Map Service (WMS) Layers or ArcGIS Server Map Layers.
Viewing GIS layer data
To view GIS layer data the layer must be made selectable in the GIS Layer Control dialog.
- Right-click in the GeoPlan Window and choose GIS Layer control from the popup menu.
- Select each GIS layer for which viewing is to be enabled and check the Selectable box for that layer.
- Close the GIS Layer Control dialog to save the changes.
- Select the information tool
on
the 
. - Click on a point or polygon from an additional GIS layer. If there is more than one object under the cursor, a selection list will be displayed. Select the object to be viewed from the list.
- The data for the object will be displayed in the GIS Layer Information dialog.
Editing GIS layer data
To edit the underlying GIS data, the layer must be made editable in the Layer Control dialog:
- Right-click in the GeoPlan Window and choose GIS Layer control from the popup menu.
- Select each GIS layer for which editing is to be enabled, and check the Editable box for that layer.
- Close the GIS Layer Control dialog and then continue as for viewing data. Any changes made on the data displayed on the GIS Layer Information dialog will be saved to the underlying GIS file when you click OK.
ESRI ® Shape files (.shp) are not editable (Read-only Editable check box) when MapXtreme is the current map control.
Displaying a text string in a shapefile layer
When displaying ESRI shapefile layers, it is possible to display a text field for each object instead of the object symbol.
To display a text field for each object, the following three fields are required in the shapefile:
- TEXTSTRING - the text that will be displayed on the GeoPlan View
- TEXT_SIZE - the size that the text will be displayed at
- TEXT_ANGLE - the angle at which the text will be displayed
When these fields are present in the shapefile, only the colour of the layer can be overridden in the GIS Layer Control dialog.
