In releases prior to ArcIMS 9.2, data from ArcIMS Image and ArcMap Image Services can be extracted using ArcMap directly or by using ArcObjects. This is possible because ArcIMS returns geometry when requested by ArcMap, and this geometry is used to show selected features. Beginning with ArcIMS 9.2 and ArcGIS 9.2, ArcIMS services do not return geometry by default. In ArcMap, selected features cannot be saved.

A parameter, returngeometry, is included in the configuration files for the query server (aimsqs.cfg) and ArcMap Server (aimsamsrv.cfg). By default, this parameter blocks geometry from being returned to a client for query requests. ArcIMS administrators have the ability to allow geometry to be passed to the client, if desired. Three options are available:

• xmlmode (default value): geometry to be returned only when GET_FEATURES outputmode is xml or newxml.
• none: geometry is not returned for any outputmode.
• all: geometry is returned for all values of outputmode. If you want ArcMap to retrieve geometry, you must use this setting. This provides backward compatibility with older versions of ArcMap, but users can save and download data.

This parameter has no affect on image requests.

ArcMap as a client has been adjusted to accommodate query results with no geometry. As a result, the following functions work with ArcIMS Image and ArcMap Image Services:

• Identify
• Select by Attribute
• Change selection color

The following functions are not supported:

• Geoprocessing
• Buffering (Buffer Wizard)
• Flash (Identify & Find results)
• Set/Create Bookmark (Identify & Find results)
• Create Selection Layer
• Change Selection symbol
• Zoom to (Selection & Find results)
• Pan to (Selection & Find results)
• Select by Location
