Contour Extraction Tool Released

The GIS and Mapping Services Division has released the Contour Extraction Tool to enable downloads of elevation contours for use in mapping software. The application contains instructions for navigating to an area of interest and running the tool to extract and download elevation contours for the area shown in the map extent. The size of the download area is limited by the scale of the map and is intended to accommodate several subdivisions at a time. Users can select from multiple formats (e.g., .shp, .gdb, .dxf) for the contours to be placed in a zip file for download.

Click the image below to open the application and run the tool. It has also been added to our Open Data site. More information on the county's topographic resources can be found here.
