San Diego Roads_All Utility

The San Diego Geographic Information Source (SanGIS) makes available for download the regularly updated Roads_All.shp shapefile which contains all the roadways in the county. It is a valuable resource for creating a roads layer on maps of the region. However, there are some issues within the data (such as leading zeros in some numeric street names) that can be obstacles to quick use; and its great detail can clutter maps at small scales.

The purpose of this project is to provide a set of models that transforms the Roads_All.shp shapefile into a geodatabase feature class named Roads_All_Extra with additional fields to aid in subtyping, symbolizing, labeling and geocoding addresses. An accompanying Roads_Extra.lyr layer file references the new feature class and provides pre-configured symbology, labeling, and scale-dependent display.

After running the utility, adding the included Roads layer to a map will produce the following at large scales (with less detail at smaller scales):

Large scale with lines and labels

Large scale with labels only

See the below referenced PDF documentation for more information and screenshots (the utility download also includes the same PDF).

The utility download is a zip file that contains:

  • 2 Python scripts.
  • 1 layer file.
  • A file geodatabase containing:
    • Configured domains.
    • 2 domain name/value tables.
    • A toolbox with a set of script tools and models.
