Virginia Department of Emergency Management (VDEM)/Virginia Geographic Information Network (VGIN) is conducting flights in 2021 in the eastern part of Virginia to capture new imagery for the Virginia Base Mapping Program (VBMP). The VBMP is providing the commonwealth with a statewide database to assist the state and localities with the deployment of NG911. As part of this program, localities can purchase 3 or 6 inch resolution imagery and features which are extracted from the imagery. Some of the features include contours, building foot prints, impervious surfaces, land cover features. We are contracting with them to extract impervious surfaces to assist Community Development staff in their efforts to meet some of state and federal environmental requirements.
Imagery is an important dataset used in several applications across the county such as the GIS Interactive Website, Spotsy GeoHub, Community Developments’ Project/Permit system and the Utilities Department’s CityWorks application. The County purchased 6 inch resolution imagery in 2007, 2013 & 2017 which has provided a consistent level imagery to allow staff to make comparisons which allow them track changes in land use and growth patterns in the County.
