Service Description: The orthoimagery in this image service was taken on 4/12/2018 over the City of Harrisonburg and between 4/13/2018 to 4/14/2018 over the surrounding Rockingham County region. 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 Fugro Geospatial:
In the spring of 2017, 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 Fugro Geospatial, Inc. to provide aerial data acquisition, 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 2017, Fugro flew the eastern third of Virginia at one foot resolution, with options for localities and other interested parties to upgrade resolution or purchase other optional products through the state contract. The middle third of Virginia was flown in 2018 and the western third will be flown in 2019. Ortho products are 1-foot resolution statewide with 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.
