Geometric Correction of historical imagery is a complicated, time consuming and expensive operation. Due to a lack of development related to streamlining these operations, a significant amount of manual processing time must be invested into current projects. A system capable of achieving reliable accuracy that considerably reduces project turnaround time is required to help manage processing costs and
improve the operating capacity.
The ability to identify and measure significant changes in target scattering and/or polarimetric parameters at known and co-located image locations provides a very powerful tool for large area military and/or environmental monitoring applications. This paper describes the techniques developed by PCI to calculate a "change measurement" derived from co-registered polarimetric parameters.
This article describes how high resolution satellite data can be used to extract accurate digital elevation model (DEM) for a mining application in the Amazon region. The resulting vertical accuracy can be within RMS error of 1.5m when using a minimum number of ground control points.
