Description (last modified by cdestigter)

We've got two tiffs here, one with pixels/inch and the other with pixels/cm resolution units. Goodness knows why, but I'd assume gdal could multiply out the resolutions properly when merging them. 

rm -f out.tif ; gdalwarp -of GTiff -co TILED=YES -co COMPRESS=DEFLATE -te 19296899.6093 -4620876.43484 19453442.6432 -4464333.40091 -ts 500 500 inch.tif cm.tif out.tif

Creating output file that is 500P x 500L.
Processing input file inch.tif.

ERROR 1: _TIFFVSetField:out.tif: Bad value 0 for "ResolutionUnit" tag

Our gdal was built from our github fork, ie ​https://github.com/koordinates/gdal/tree/252ed79 which is basically 1.10 branch from about 10 days ago.
