Hi all, I'm working on the osgEarth (http://www.osgearth.org) WCS plugin and I'm trying to connect to MapServer as a WCS to access SRTM data.
Things look great for the most part, but I'm having issues that tile edges don't line up exactly, the elevations are slightly off. I am specifying bilinear resampling in the map file via PROCESSING "RESAMPLE=BILINEAR". The edges of the bounding boxes I'm specifying should be lining up exactly with the neighboring tiles. The SRTM I am using is a single tiled geotiff with overviews. Are there any tricks to getting the edges of the tiles to match up exactly? Thanks!
