Viewing and editing GIS layer data
InfoWorks WS Pro allows you to view and edit data in additional GIS layers that have been loaded onto the GeoPlan window. InfoWorks WS Pro displays 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 Layer Control dialog, as covered below:
- Right-click the GeoPlan window and choose Layer Control.
- Select each GIS layer for which viewing is to be enabled and check the Selectable box for that layer.
- Save the changes by clicking OK or Apply, and close the Layer Control dialog.
- Select the information tool
on
the Tools toolbar. The cursor changes
to 
. - Click 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, as covered below:
- Right-click the GeoPlan window and choose Layer Control.
- The next step depends on the GIS component being used:
- MapX, MapXtreme, and ArcGIS: select each GIS layer for which editing is to be enabled, and check the Editable box for that layer.
- MapObjects: check the Editable box on the grid for each of the GIS layers for which editing is to be enabled.
- Close the 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 OK is clicked.
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 window
- TEXT_SIZE - the size at which the text will be displayed
- 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 Layer Control dialog.
