GIS Data

Geographic data is available in ESRI shapefile format from our Open Data portal. You will need GIS software such as ESRI's ArcGIS or ArcGIS Explorer (free download) to view, manipulate or analyze the geospatial data.

Large datasets can be found on the Land Records and Elevation pages under GIS Data in the left rail.


Current and historic high-resolution aerial photography is available for download in MrSid format. The files may be viewed in ArcGIS, AutoCAD, or in your Windows web browser using ExpressView Browser Plug-In.

LiDAR Data

LiDAR (Light Detection and Ranging) uses laser and the reflected light to detect and measure surface features. Raw high-resolution point cloud elevation data is available as LAS files on request.
