Virginia – March 21, 2013 – Merrick & Company’s geospatial and surveying team (http://www.merrick.com/Geospatial) was awarded the third installment with Henrico County, VA, to continue the collection and processing of digital orthophototography and oblique imagery products and services. The work is part of a three year cycle and includes capturing aerial digital oblique imagery of a 340 square mile area. Having worked with Henrico County and the county’s GIS database, Merrick’s knowledge of the County’s control network, coordinate system, and tile structure will ensure meeting the current and future GIS needs of the County.
For the initial cycle, Merrick is providing the countywide aerial photography that supports the imagery creation and mapping-related activities of Henrico County. The data is being collected carrying remote sensing technologies such as the Leica ADS40. With the use of aircraft, digital sensors, airborne GPS units and inertial measurement unit (IMU) methods; data is post processed and integrated into a precise location that is used for geo-referencing and to support subsequent photogrammetric mapping and orthorectification of the digital imagery. Merrick’s annual aerial updates to the County will be used for regional planning, tax assessment, and engineering purposes.
