Description:

Abstract:: The Tijuana River Watershed digital geology file was created as part of the Tijuana River Watershed GIS database project. This digital layer consists of polygons of rock formations in the Tijuana River Watershed.
Purpose:: The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. One of the layers in the dataset is a digital geology layer. This layer provides information on the underlying rock formations of the watershed, important for environmental studies and modeling.

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 be complete as compiled directly from the source materials. No generalization of source data was performed.

Positional_Accuracy:

Horizontal_Positional_Accuracy:

Horizontal_Positional_Accuracy_Report:: Horizontal positional accuracy of the source material is unknown.

Vertical_Positional_Accuracy:

Vertical_Positional_Accuracy_Report: Vertical positional accuracy of the source material is unknown.

Source_Contribution:

This source contributed geologic data such as rock formations and faults for the U. S. and Mexico on one map.

Process_Step:

Process_Description:

The data was digitized from the source paper map. Lines were smoothed using a spline function and topology was constructed. The source map uses different geology classification systems for Mexico and the United States. The United States classification was utilized. George Morgan modified some polygons and classifications in 2004.
