Enhanced Layer Functionality

5 To turn the spatial query filter off, clear the Use MapGuide Server’s Spatial 

Filter checkbox.

The default client window size determines the size of the spatial filter you use 
to limit data returned by a spatial query. Autodesk MapGuide allows you to 
change the spatial filter’s extents by applying clipping adjustments that 
either increase or decrease the dimensions of the bounding box so that it is 
bigger or smaller than the default client size window. The clipping adjust-
ments you apply can be set to either positive or negative values, depending 
on whether you want to make the spatial filter larger or smaller than the 
default client window size. The units for the clipping adjustment are the 
same as the units established for the map coordinate system. 

1 Open the map containing the layer to which you want to apply clipping 

adjustments.

2 Double-click the name of the layer in the list to the left of the map. The 

Map Layer Properties dialog box is displayed.

3 In the Map Layer Properties dialog box, click the Data Sources tab, as 

shown in the following illustration.
