GIS and Mapping Services

GIS and Mapping Services administers the county Geographic Information System (GIS) and iGIS map portal. Our mission is to coordinate, manage and facilitate GIS at departmental, office and enterprise levels. We create and manage E911 site addresses and street names. We serve as primary custodian for county GIS data, aerial imagery and LiDAR topography contours.  GIS and Mapping Services fulfills public requests for GIS data, mapping and imagery services.

A step-by-step guide will help you get the most out of the iGIS map portal. For assistance, please contact us at (540) 394-2148.  (If you have problems loading the map portal, you may try to delete your browser's history/cache.)

A parcel tax exempt field is available using the iGIS Map Portal Discovery tool.  This field will indicate the type of tax exemption for a specific parcel.

Our iGIS Map Portal has been in continuous use since 2003. Our current version of the iGIS Map Portal was designed by Montgomery County in close partnership with Datel Group Company.

For questions or errors regarding real estate parcel ownership, legal descriptions, acreage, assessed values, recent sales, etc. please contact the Commissioner of the Revenue's Office at (540) 382-5710. 

The iGIS Map Portal uses the 2015 Commonwealth of Virginia aerial imagery.
