Part 2, Digital orthoimagery (revised) supports exchange of orthoimagery data. It provides a base on which to collect, register, and integrate digital orthoimagery data.
Part 2 specifies data content and a logical structure for description and interchange of digital orthoimagery; provides guidelines for acquisition and processing of imagery; specifies documentation of acquisition and processing; focuses on images sensed in the visible to near infrared portion of the electromagnetic spectrum; stresses complete and accurate reporting of information relating to quality control and standards employed in testing orthoimagery data; and includes a data dictionary based on its conceptual schema.

Background
Work on the Geographic Information Framework Data Standard began under the Geospatial One-Stop e-Government initiative in the early 2000s. The Geographic Information Framework Data Standard helps fulfill a primary objective of the National Spatial Data Infrastructure (NSDI), namely, the creation of common geospatial data for seven Framework National Geospatial Data Asset (NGDA) themes that are of critical importance to the NSDI.
The FGDC previously endorsed Part 2, Digital orthoimagery, of the Geographic Information Framework Data Standard, and parts for the other Framework NGDA themes, in 2008. The revision of Part 2 primarily replaces analog camera references with digital sensors and recognizes satellite technology for digital orthoimagery production.
The U.S. Geological Survey, Department of the Interior, and the U.S. Department of Agriculture carried out initial review of Part 2, Digital orthoimagery of the Geographic Information Framework Data Content Standard. Part 2 was revised with support from members of the American Society for Photogrammetry and Remote Sensing (ASPRS). It subsequently underwent a 90-day public review period.
At its June 18, 2015 meeting, the FGDC Standards Working Group recommended that the FGDC Coordination Group approve Part 2, Digital orthoimagery (revised), of the Geographic Information Framework Standard for FGDC endorsement. The FGDC Coordination Group approved Part 2, Digital orthoimagery (revised) for FGDC endorsement on August 26, 2015. FGDC Steering Committee endorsement was the final step in the FGDC standards approval process.
