- Abstract:
-
The Trolley Rail coverage was created as part of the Tijuana River Watershed GIS database base project. It includes information on the San Diego Trolley stations and location of the rails that the San Diego Trolley operates on within the vicinity of the watershed.
- Purpose:
-
The Tijuana River Watershed GIS Database project provides a fully integrated cross border geographic information system. It is important to understand the transportation opporutnities and linkages that exist in and around the Tijuana River Watershed.

- Attribute_Accuracy:
-
- Attribute_Accuracy_Report:
-
All attributes created during the data generation phase were verified by comparing both the dataset and the spatial coverage, but no formal tests were performed.
- Completeness_Report:
-
The Trolley coverage was created by extracting linework from the San Diego Association of Governments (SANDAG) railroad coverage. At the time of coverage completion, the linework is believed to be correct.
- Logical_Consistency_Report:
-
These data are believed to be logically consistent, though no tests were performed. Line geometry is topologically clean.

-
- Horizontal_Positional_Accuracy:
-
- Horizontal_Positional_Accuracy_Report:
-
The data were created using existing data. The horizontal positional accuracy of the source material is unknown.

-
- Process_Description:
-
The data was first collected from the San Diego Association of Governments website. The SANDAG data was reprojected from its original STATEPLANE, NAD83 to the Tijuana River WAtershed standard of UTM, NAD83. The rail lines pertinent to the Trolley were SELECTED and PUT into a new coverage using the item in the original railroad coverage that delineated which rail lines the Trolley was active on.
