This approach, coupled with the capability to orthorectify so 
as to create a much more precise image match than can be 
obtained by "rubber sheeting" polynomial fits used by most 
image processing systems, promises to permit a whole new 
order of high resolution features coupled with the context of 
multispectral information. 
5. Conclusion 
SAIC is active in developing integrated 
photogrammetric systems. The systems which we have 
developed are not yet complete, but they are continually 
evolving toward completeness. We are using technology 
developed for government customers, which is in the public 
domain, to build systems which produce data for the private 
community. These systems also benefit the government in 
that future related developments are more efficient because of 
the integrated, coordinated, approach to development. This 
approach has allowed SAIC, which until three years ago had 
never done commercial photogrammetric work, to become a 
key supplier of orthophotos to both the U.S. Government, 
and local governments around the world.
