I have a pretty fresh install of the latest Boundless OpenGeo stack (v4.5). I have a requirement to host some stereo satellite imagery. I'm using the sample imagery over China provided by DigitalGlobe (https://www.digitalglobe.com/product-samples). The .zip file is quite large and contains a directory for panchromatic imagery, one for multispectral imagery, and a GIS_FILES directory that seems to just contain various footprint shapefiles. Each of the imagery directories contain many supporting files: .ATT, .EPH, .GEO, .IMD, .RPB, .STE, .TIL... DigitalGlobe has an Imagery Support Data Document (https://www.digitalglobe.com/sites/default/files/ISD_External.pdf) that explains the information in each file. They all seem to provide information about the image pairs, overlaps, etc.
I'm confused how to properly host this data in GeoServer.
Should the two GeoTIFFs be added to independent stores in GeoServer?
Is there some other sort of mechanism that keeps the two images together or contains the metadata in the DG provided files?
