Service Description:

The orthoimagery in this image service was taken between 2/1/2022 to 4/2/2022. It was provided by the Commonwealth of Virginia, specifically through the Virginia Geographic Information Network Division (VGIN) to support the state's base mapping program. Imagery is displayed in natural color with the following band order: red (band 1); green (band 2); blue (band 3). The dataset's coordinate system is WGS 1984 Web Mercator (Auxiliary Sphere). A cache was built containing 11 levels ranging from 1:288,895 to 1:282 from source image tiles (GeoTIFFs). The spatial resolution is 3-inches over the City of Harrisonburg and 12-inches for surrounding Rockingham County areas.

Metadata below provided by the imagery contractor SURDEX:

In the spring of 2020, the Commonwealth of Virginia, through the Virginia Geographic Information Network Division (herein referred to as VGIN) of the Virginia Information Technologies Agency (VITA) contracted with SURDEX Corporation to provide digital aerial imagery, ground control, aerial triangulation and development of statewide ortho quality DEM and digital orthophotography data. The Virginia Base Mapping Program (VBMP) update project is divided into three collection phases: In 2021, SURDEX acquired the eastern third of Virginia at 12-inch imagery resolution, with options for localities and other interested parties to upgrade the imagery resolution and purchase other optional products through the state contract. The central third of Virginia was acquired in 2022 with options for localities and other interested parties to upgrade the imagery resolution and purchase other optional products through the state contract, and the western third will be flown in 2023 with options for localities and other interested parties to upgrade the imagery resolution or purchase other optional products through the state contract. The orthoimagery base product is 12-inch resolution statewide with locality upgrades to 6-inch resolution tiles and 3-inch resolution tiles in various regions within the project area. The Virginia Base Mapping project encompasses the entire land area of the Commonwealth of Virginia over 4 years. The State boundary is buffered by 1000'. Coastal areas of the State bordering the Atlantic Ocean or the Chesapeake Bay are buffered by 1000' or the extent of man-made features extending from shore.
