edit the attributes of a geometry by which the layer was geocoded, the 
spatial location of that geometry is repositioned accordingly. 

•  Redline (redline layers only)-This geometry shape is used for the GIS 

Redline layer automatically produced in Enterprise databases. GIS 

Redline layers are special layers that are the repositories of all redlines 
produced by the redlining/sync process as part of an Enterprise 

database subscription. The Redline geometry shape is stored as a 
Planar type. 

If the layer is a point layer, Planar is the only Geometry Shape option available 
unless the point layer was geocoded and then the option is Geocode Points. If 
the layer is a polygon layer, the Geometry Shape options are Planar and 

Spherical. If the layer is a line layer, the Geometry Shape options are Planar, 
Spherical, and Topological. If the layer is a redline layer, Redline is the only 

Geometry Shape available. 
Note  The Geometry Shape option is disabled when there are uncommitted 

edits against the layer. 

6.  To change the minimum and maximum zoom levels at which the layers 

display on the map, select the zoom levels from the Min. Zoom Level and 
Max. Zoom Level drop-down lists. 

7.  To change on which map the layer is viewed (primary, secondary, or both), 

select the option from the Map drop-down list. 

8.  To change the layering level, click inside the Layering Level text box and 

edit the value. For more information, see Reordering Layers. 

9.  If you want to show labels related to the layer, select the Labels check box. 
10. Click OK. 

 

This Help topic describes features that are available in XMap 
GIS Editor and XMap GIS Enterprise. 

 
Use the Buffer feature in XMap to create a buffer around a geometry based on a 
specific distance. This tool is helpful in GIS spatial analysis when proximity issues are 

of concern, such as site planning or risk assessment. 
To Create a Buffer 
Use the following steps to create a buffer around a geometry. 

1.  Click the GIS tab. 
2.  Click the Workspace subtab if it is not selected. 
3.  Click Tools and then click Buffer.  

The Buffer Layer dialog box opens. 

4.  From the Source Layer drop-down list, select the layer that for which you 

want to create a buffer (only layers in the workspace will display in this list). 

5.  Select the Source Geometries option: 

•  All to build buffers around all geometries in the source layer. 
•  Selected to build buffers around selected geometries in the source 

layer. (Selections are made with the GIS tools on the toolbar or by 
selecting attribute records within the Attributes subtab.)
