CALVEG Tile Index

This polygon layer consists of boundaries for the ecological tile units and CALVEG zone units currently being used to tile the EVEG (existing vegetation) dataset. Attributes from Ecological Units of California (Ecological Domain, Division, Province, Section and Subsection) have been incorporated into this layer. This layer was developed as a tiling system to serve out logical portions of vegetation data for use in land management issues such as forest-wide planning efforts, wildlife habitat mapping and fire risk assessment.

CALVEG Data

Existing vegetation GIS maps are comprehensive vegetation databases that meet regional and national vegetation mapping standards. Map attributes consist of land use Anderson 1, life form cover type, FGDC physiognomic order, class and subclass, vegetation types using the CALVEG classification system and forest structural characteristics. Forest productivity is determined by CALVEG type. The CALVEG classification is a provisional system that meets the floristically based level of the National Vegetation Classification Standard hierarchy. The CALVEG classification descriptions and keys are being maintained and updated by the Pacific Southwest Region. For more detailed information regarding the CALVEG data, please see the Existing Vegetation layer description.

CALVEG Accuracy Assessments

Accuracy assessment of maps improves their utility by providing the user of the maps with information about the nature, magnitude, frequency and source of errors. For more detailed information regarding the Accuracy Assessments, please see Accuracy Assessment Reference Data, Accuracy Assessment Details, and Accuracy Assessment Interpretation.

All Personal Geodatabases are maintained in Albers NAD83. Here is a document that gives further information about the projection.
