Scope
Digital orthoimagery is one of the basic digital geospatial data framework themes as envisioned by the Federal Geographic Data Committee. This part of the Geographic Information Framework Data Content Standard specifies data content and logical structure for the description and interchange of framework digital orthoimagery. To a certain extent, it also provides guidelines for the acquisition and processing of imagery (leading toward the generation of digital orthoimagery) and specifies the documentation of those acquisition and processing steps. The primary focus of this part is on images sensed in the visible to near infrared portion of the electromagnetic spectrum. However, images captured from other portions of the electromagnetic spectrum are not precluded.
Purpose
It is the intent of this part of the Framework Data Content Standard to set a common baseline that will ensure the widest utility of digital orthoimagery for the user and producer communities through enhanced data sharing and the reduction of redundant data production. The framework will provide a base on which to collect, register, and integrate digital geospatial information accurately. This part is intended to facilitate the interchange and use of digital orthoimagery data under the framework concept. Because of rapidly changing technologies in the geospatial sciences, this part covers a range of specification issues, many in general terms. This part stresses complete and accurate reporting of information relating to quality control and standards employed in testing orthoimagery data.
