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 to view, manipulate or analyze the geospatial data.

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


The 2023 aerials are now available!

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

 Updated LiDAR data from 2018 are available

LiDAR (Light Detection and Ranging) uses laser and the reflected light to detect and measure surface features. Raw high-resolution point cloud elevation data and derivatives are available on request. Countywide spot elevation GIS files and a raster DEM may also be downloaded.
