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. Vegetation was interpolated from 10 m SPOT satellite imagery and NOAA aerial photographs at a resolution of 1:50,000. Vegetation was groundtruthed through field work in 1994 by SDSU researchers. * Sinopsis: La cobertura de vegetación fue creada como parte del proyecto de la base de datos GIS de la cuenca del río de Tijuana. Incluye la información sobre las clases generales de vegetación en la cuenca. Una clasificación Holland modificada fue utilizada para identificar los grupos de vegetación. Las áreas ribereñas fueron trazadas en una resolución de .5 acres, mientras que las áreas no ribereñas tienen una unidad mínima de trazado de 5 acres. La vegetación fue interpolada a partir de imágenes SPOT de satélites de 10 m y de fotografías aéreas de NOAA en una resolución de 1:50000. La medición para la vegetación fue calibrada (verdad en tierra firme) a través de trabajo de campo de investigadores de SDSU en 1994.

Use_Constraints:
While this data have been collected for use in spatial analysis and decision making, and for use in Geographic Information Systems, San Diego State Univeristy, Department of Geography, the Center for Earth Systems Analysis Research, and El Colegio de la Frontera Norte cannot guarantee the accuracy of the data. As with any spatial data, issues of scale, taxonomic classification, resolution, and precision will affect the perceived accuracy of the data. Users are ultimately responsbile for the appropriate application of and use of this data. * Limitaciones de Uso: Mientras que estos datos se han compilado para su uso en análisis espacial y toma de decisiones, así como para su uso en sistemas de información geográficos, la universidad técnica CalPoly en Pomona y la Universidad Estatal de San Diego no pueden garantizar la exactitud de los datos. Como con cualquier dato espacial, las consideraciones de escala, clasificación taxonómica, resolución y precisión afectan la exactitud percibida de los datos. Los usuarios, en última instancia, son responsables del uso y aplicación apropiados de estos datos.

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.

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 watershed. Clipped to study area and attributes translated by IRSC. * Descripción del Proceso: Las observaciones de campo de la vegetación en la parte mexicana de la cuenca fueron trazadas sobre hojas transparentes de mylar sobrepuestas a fotografías aéreas a una escala de 1:12500. Las fotografías y los mylars se utilizaron para avanzar la digitación de los límites del polígono de la vegetación usando imágenes SPOT como referencia. Una vez que los límites fueron determinados, la topología fue generada y se fijaron los atributos de los polígonos con los códigos y las descripciones de vegetación apropiados. La parte mexicana fue posteriormente combinada con la cobertura de vegetación obtenida de la Asociación de Gobiernos de San Diego y del condado de San Diego para que la parte de los Estados Unidos completando así la cobertura total para la cuenca. Anexado al área de estudio y atributos traducidos por el IRSC.
