|Priority Development Areas||Priority Development Areas (PDAs) are areas where new development will support the day-to-day needs of residents and workers in a pedestrian-friendly environment served by transit. While PDAs were originally established to address housing needs in infill communities, they have been broadened to advance focused employment growth. Local jurisdictions have defined the character of their PDAs according to existing conditions and future expectations as regional centers, city centers, suburban centers or transit town centers, among other place types.||Association of Bay Area Governments|

|Terrain||Hillshades (color and grayscale) were downloaded in parts from USGS websites and assembled into single raster datasets. These different hillshades were then assembled into a map service providing topographic relief from region to local scales.|
The ~90m hillshade data, used for small scale viewing, was derived from the Shuttle Radar Topography Mission (SRTM) 3 arc-second dataset. Open Source software was used to create a hillshade from the elevation data provided by the SRTM.
The ~10m and ~30m hillshade data, used for medium and large scale viewing, are from the National Elevation Dataset (NED) 1/3 and 1 arc-second datasets. The NED data is provided as a hillshade by default.
The color hillshades (all datasets) were created by applying a color map to the original, black and white hillshades.
