I have application where user draws arbitrary line over a map, and is presented with cross-section of terrain from DTM under that line. At the moment, this is supported by a custom DTM format to make this retrieval fast and memory efficient
(since can be dealing with very large high-resolution data). I would like to extend the functionality to handle other raster dtm formats and doing this via geoserver seems possible. It can be done via repeated getfeatureinfo calls along the line but this is
pretty inefficient. Is this something a WPS service could do? Has anyone already done it?
