Hi Adrian, generally, yes a LOD system would be nice, but it would need considerable changes on the btg format or a switch to something new. I'm currently investigating how to make elevation calculation for the terrain easier and more versatile. I want to use gdalchop for general processing as gdal reads almost all kinds of raster formats. So we would no longer have to rely on hgtchop, srtmchop and demchop (yes, it's mad). Also, depending on what is possible, i would like to get rid of terrafit. We have great SRTM data, reduce the amount of points and then have to interpolate like mad when we need the elevation of a certain point. GDAL has interpolation routines included (beyond linear interpolation) and I'd like to make use of that. I noticed yesterday, that there is already gdallocationinfo which reads the elevation on the fly for a given lat/lon. This might be worth investigating.
