- Description:

- Abstract:
-
The Tijuana River Watershed digital international border was created as part of the Tijuana River Watershed GIS database project. The border was obtained from the San Diego Association of Governments and positionally modified to match the coverages in the GIS database.
- Purpose:
-
The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. The international border coverage is one of the base cartographic layers.
- Supplemental_Information:
-
The international border is not to be taken as a definitive boundary between the United States and Mexico.

- 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 international border is dependent on the sources used by the San Diego Association of Governments to construct the boundary of the County of San Diego. The international border might change as more accurate sources become available.

-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:

The data were obtained from the San Diego Association of Governments. The accuracy of the sources and compliation methodology is unknown, therefore, the horizontal accuracy is unknown.

-
- Process_Description:
-
The San Diego Association of Governments County coverage was obtained and re-projected into UTM, NAD83, Zone 11. Arc segments not along the international border were deleted along with all theme attributes. The coverage was then compared to the SPOT image of the region. The international border arc was shifted where necessary to match the SPOT image.

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.
