The following are sample item definitions for the various attribute tables used by the 2.11 Toolbox. Specific Toolbox installations may differ slightly. However, it is important that items that are defined numerically here be defined as numeric in your coverages, and character items should remain character type. Furthermore, it is critical that definitions of items be consistent between the arcs and the project sections.The Sys/User column indicates whether the item was defined by the system, or is a user defined item. The Item Name, Width, Output, Type, and N.Dec columns indicate how the item is defined in ArcInfo.
For general information about coverages, please refer to Coverages Used by the 2.11 Toolbox. For more specific information about the attributes that EMME/2 uses, see Standard EMME/2 Attributes.
