Problem: The Spatial Analyst Functional Reference is not accessible from the ArcGIS Desktop Help system
In some cases, the Spatial Analyst Functional Reference is not launched from the link directly under the Spatial Analyst documentation in the contents of the ArcGIS Desktop Help system.
This is a known issue with ArcGIS 8.2 and 8.3.
Solution or Workaround
In previous versions, there are two work-arounds to this problem. Access the Spatial Analyst Functional Reference from the Raster Calculator within the Spatial Analyst toolbar or access it directly from disk.
- Option 1:
1) Right-click the Spatial Analyst toolbar and click Raster Calculator.
2) Click 'About Building Expressions' and click the link 'Functional Reference' for Spatial Analyst functions.
- Option 2:
1) Navigate on disk to the %ARCHOME% directory, typically C:\arcgis\arcexe82\, and click the Help folder.
2) Double-click CommandRef.chm to launch the Spatial Analyst Functional Reference.
To make it more easily accessible, create a shortcut on the desktop.
