esult Tiff will still be UInt16. Problem has been solved, by explicitly adding "PIXELTYPE SIGNEDINT" in the .HDR files, and the result is now correct. On Sun, Dec 6, 2009 at 11:13 AM, Hermann Peifer wrote: > Bruce Liang wrote: > >> Hello, guys, >> >> I have

[gdal-dev] no date value by gdal_merge from DEM to GTiff ?

2009-12-05 Thread Bruce Liang
Hello, guys, I have several DEMs from USGS GTOPO30, and by merging them with gdal_merge.py, it seems the no data value can not be assigned? the command is like: gdal_merge.py -of GTiff -o Europe.tiff -n - -co "PROFILE=GeoTIFF" -co "INTERLEAVE=PIXEL" -co "COMPRESS=NONE" -co "TILED=YES"
