The query tool you mentioned is for PEDRs, I'd like to look at the globally gridded MEGDR products.
When I use the ODE data product search (as suggested at the top of the PEDR Query Tool 2 page), I can bring up a file, for example MEGT90N180GB.IMG, however, the PDS product files and Derived files do not include a simple text table (lat, lon, elevation), it only includes more images and some shapefiles.
What is the easiest way to convert the MEGDR products to a simple text table?
