Description:
Abstract:
The Lakes coverage was created as part of the Tijuana River Watershed GIS database project. The lakes were created using both existing San Diego Association of Governments data and original data. It is not meant to be a definitive file.
Purpose:
The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. The digital lakes file illustrates the large waterbodies within the watershed. It is not meant to be a definitive file.
Supplemental_Information: The lakes file is not meant for legal use.

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:
The boundaries of the lake waterbodies are dependent on the sources and the source dates. Since the waterbodies are mostly reservoirs, the size of the waterbodies may increase or decrease during the years dependent on precipitation and policy decisions.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
Some of the data were digitized from a SPOT image as a backdrop, while others were obtained from the San Diego Association of Governments. The accuracy of the sources and compilation methodology of the non-original data is unknown, therefore, the horizontal accuracy is unknown.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
Some of the data were digitized from a SPOT image as a backdrop, while others were obtained from the San Diego Association of Governments. The accuracy of the sources and compilation methodology of the non-original data is unknown, therefore, the vertical accuracy is unknown.

Process_Step:
Process_Description:
The lakes polygons were generated by selecting the waterbodies from a digitized landuse coverage which was generated for the Mexico side of the border. These polygons were put into a new coverage. For the United States side of the border, the lake polygons were obtained from the San Diego Association of Governements (SANDAG) Digital GIS Lakes coverage for the county of San Diego. The lakes within the watershed boundary were selected and placed into the coverage with the Mexican waterbodies. The SANDAG polygons were then compared to the SPOT image used for digitizing the landuse and were shifted if necessary. Attributes were then added to all the polygons.

While this data have been collected for use in spatial analysis and decision making, and for use in Geographic Information Systems, San Diego State University, 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 responsible for the appropriate application of and use of this data.
