Description:
Abstract:
The Tijuana River Watershed Digital Boundary File was created as part of the Tijuana River Watershed GIS database project. The Digital Elevation Model was constructed using USGS and INEGI contour lines. It is not based on legal descriptions.
Purpose:
The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. One of the layers in the dataset was a digital elevation model.

Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
All attributes created during the data generation phase were verified by comparing values 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.
Completeness_Report:
The elevation contours were delineated using numerous USGS 7.5 Minute, and INEGI 1:50000 Topographic Maps. The elevations might change as more accurate data becomes available.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data were generated from contours scanned from USGS 7.5 Minute, and INEGI 1:50000 Topographic maps. Since the accuracy of the INEGI maps is unknown, horizontal accuracy is unknown.
Vertical_Positional_Accuracy:
Vertical_Positional_Accuracy_Report:
The data were generated from contours scanned from USGS 7.5 Minute, and INEGI 1:50000 Topographic maps. Since the accuracy of the INEGI maps is unknown, vertical accuracy is unknown.

Process_Step:
Process_Description:
Topographic maps from both sides of the international border were scanned and converted into digital images. These images were then vectorized in ArcInfo and edited to correct spatial and attribute information. The vector coverages for each topo sheet were then merged together and edgematched for each side of the border. Finally, the two merged contour line coverages were merged at the international border. From this one merged contour coverage, a digital elevation model was constructed with a resolution of 30 meters.

Distribution_Liability:
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 these data.
