•Mosaic tiles.
•Project to common coordinate system (Albers).
•Vertically warp DEMs so elevations match at edge of overlap (3000-m transition).
•Subsample to 5-m cell size.

Mosaic prior to any coordinate-system projections. Be sure to use bilinear interpolation when projecting. Warping and subsampling done with Fortran code.
