- Abstract:
-
The Freight Rail coverage was created as part of the Tijuana River Watershed GIS database base project. It includes information on the location of the railroad that freight is shipped on in and around 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 opportunities 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 freight 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 digital data. The horizontal positional accuracy of the source material is unknown.

-
- Process_Description:
-
The data was first collected from the San Diego Association ofGovernments website. The SANDAG data was reprojected from itsoriginal STATEPLANE, NAD83 to the Tijuana River Watershed standard of UTM, NAD83. The rail lines pertinent to thefreight rail were SELECTED and PUT into a new coverage using the item in the original railroad coverage that delineatedthe freight lines. The freight coverage was then edited further by increasing the accuracy of the location of the rail lines usingthe San Diego/Tijuana SPOT image.
