State

State agencies often undertake large scale digital orthophotography and mapping projects in response to a specific need. For an environmental assessment, they may select color infrared imagery, while for floodplain mapping they select natural color digital orthoimagery. The imagery often covers large, rural areas and is used to manage undeveloped areas at a lower resolution and larger mapping scale, rather than urban areas of counties or cities, which most often use higher resolution imagery at larger mapping scales.

Surdex routinely works on projects for states. Recent projects include work for the States of Missouri, the Missouri Department of Conservation, the Texas Water Development Board, State of North Carolina, Sate of Mississippi, and Illinois DOT, Iowa DOT, and MN Geo.

Frequently, a project area is covered by several jurisdictions, so multiple entities may be involved – for example, several state agencies, or agencies from multiple states, or even state agencies working with a federal agency. For example, the Missouri NRCS and the USDA worked in unison on the Missouri Erodible Lands project, where both entities held an interest in the project area. Similarly, the Texas Natural Resources Information System (TNRIS) manages imagery within the state, serving multiple entities with overlapping regional interests.
