I routinely make pdfs from large collections of remote sensing images 
(.png or .pdf) using ConTeXt.  This allows me to include metadata and 
tables or plots of statistical summaries.  PDF is the obvious choice 
because it supports use of scalable overlays (continents, coordinate 
meshes, annotations, etc.).

I expect increasing use of pdf format to support scalable annotations and 
overlays in future remote sensing toolchains.  At present many were 
designed for raster images and lack the accuracy to produce publication 
quality overlays of vector data.
