This document identifies the information required to determine the relationship between the position
of a remotely sensed pixel in image coordinates and its geoposition. It supports exploitation of remotely
sensed images. It defines the metadata to be distributed with the image to enable user determination of
geographic position from the observations.
This document specifies several ways in which information in support of geopositioning can be
provided.
a) It may be provided as a sensor description with the associated physical and geometric information
necessary to rigorously construct a PSM. For the case where precise geoposition information is
needed, this document identifies the mathematical equations for rigorously constructing PSMs that
relate 2D image space to 3D ground space and the calculation of the associated propagated errors.
This document provides detailed information for three types of passive electro-optical/ IR sensors
(frame, pushbroom and whiskbroom) and for an active microwave sensing system SAR. It provides
a framework by which these sensor models can be extended to other sensor types.
b) It can be provided as a TRM, using functions whose coefficients are based on a PSM so that they
provide information for precise geopositioning, including the calculation of errors, as precisely as
the PSM they replace.
c) It can be provided as a CM that provides a functional fitting based on observed relationships
between the geopositions of a set of GCPs and their image coordinates.
d) It can be provided as a set of GCPs that can be used to develop a CM or to refine a PSM or TRM.
This document does not specify either how users derive geoposition data or the format or content of the
data the users generate.
