Description:
Abstract:
The vegetation coverage was created as part of the Tijuana River Watershed GIS database project. It includes information on the general vegetation classes in the watershed. A modified Holland classification was used to identify the vegetation groups. Riparian areas are mapped at a resolution of .5 acre, while non-riparian areas have a 5 acre minimum mapping unit.
Purpose:
The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. The vegetation coverage is one of the layers in the data base. It includes information on the general vegetation classes in the watershed. A modified Holland classification was used to identify the vegetation groups. Riparian areas are mapped at a resolution of .5 acre, while non-riparian areas have a 5 acre minimum mapping unit.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes created during the data generation phase were verified by comparing the lines in both the dataset and the spatial coverage, but no formal tests were performed.
Logical_Consistency_Report:
These data are believed to be logically consistent, though no tests were performed. Line geometry is topologically clean.
Completeness_Report:
These data are believed to represent general vegetation classes at a watershed level of measurement. The polygon boundaries are based on field mapping utilizing 1:12500 scale aerial photography and SPOT imagery for heads-up digitizing of the mapped areas. The vegetation clusters were believed accurate at the time of mapping, however, as time has past, precipitation and other environmental factors may have altered the polygon boundaries.

Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data were generated from field observations and remotely sensed imagery. The accuracy of these sources is unknown, therefore the horizontal accuracy is unknown.

Vegetation polygons for the United States portion of the Tijuana River Watershed.
Process_Step:
Process_Description:
Field observations of the vegetation in the Mexican portion of the watershed were mapped onto clear mylar sheets overlaying 1:12500 aerial photography. The photos and mylars were then used to heads-up digitize the vegetation polygon boundaries using a SPOT image as a reference. Once the boundaries were completed, topology was generated and the polygons were attributed with the proper vegetation codes and descriptions. The Mexican portion was then merged with vegetation obtained from the San Diego Association of Governments and the County of San Diego for the United States portion to complete the overall coverage for the .
