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.
