LROC NAC DTMs as bias-corrected Cloud-Optimized GeoTIFFs
One folder per LROC NAC DTM product, each containing:
<product>_h.tif: height in metres (float32, NaN = nodata), COG with overviews, LERC_ZSTD compressed with a hard per-pixel error bound of 0.02 m. Heights are the source DTM minus a smooth low-frequency bias (Gaussian-smoothed difference to the LOLA global DEM, sigma 2.0 km), so tiles line up with the global baseline. Datum: lunar reference sphere, R = 1737.4 km.<product>_w.tif: uint8 blending weight on a coarse grid (0 at the DTM edge, ramping to 255 at 400 m inside), for feathered mosaicking.<product>_meta.json: CRS, bounds, pixel size, bias statistics and processing parameters.
