Classification and Assessment with Landsat of Visible Ecological Groupings (CALVEG)
Description / purposeCALVEG is a USDA Forest Service product providing a comprehensive spatial dataset of existing vegetation cover over California. The data were created using a combination of automated systematic procedures, remote sensing classification, photo editing, field based observations. The Pacific Southwest Region (R5) Information Management staff is responsible for producing comprehensive spatial and tabular databases for existing vegetation, in addition to other duties. A mapping methodology has been developed to capture vegetation characteristics using automated, systematic procedures that efficiently and cost-effectively map large areas of the state with minimal bias and is supplemented with onsite field visits when appropriate. Map attributes consist of vegetation types using the CALVEG classification system and forest structural characteristics such as tree and shrub canopy cover and tree stem diameters. Data collected and managed by Forest Service programs is available in a map service and two downloadable file formats - in a shape file and an ESRI file geodatabase. Metadata is available that describes the content, source, and currency of the data. You can filter the list by the topic categories in the menu at the left to help you find information you are interested in. You can view the feature classes in a single dataset by clicking on the name of the parent dataset at the bottom of the abstract.
