Gravel Road

CDGRS Mapper Geographic Information System (GIS)

The Dirt and Gravel Road Program maintains a customized GIS interface called Mapper to keep track of over 16,000 potential and completed project sites throughout Pennsylvania. PA's Conservation Districts utilize the CDGRS Mapper system for all aspects of project tracking for sites within their County. Districts also use Mapper as a paperless reporting system to report deliverables and financial details about completed road projects to the State.


Public Resources

Conservation District Resources

Conservation Districts are required to attend a GIS training before they are provided with an ID and Login to allow them to access the GIS system to make changes for their county.   Annual Summary Reports require Districts to update their GIS system with all completed and Contracted projects by January 15 each year.  To log into the CDGRS Mapper system once you have attended a training,  click the green “login” button at the top right of this page.
