Marcel, The best would be that you prepare something that others can try in a fully reproducable way, i.e. provide source(s) image(s) and all the exact command lines you use. Even Le vendredi 26 septembre 2014 19:41:01, Marcel Blom a écrit : > Because of some problems with GDAL 1.7.0b2 in FWTo

[gdal-dev] GDALwarp creates some darker images after update from 1.7.0b2 to GDAL 1.11.0

2014-09-26 Thread Marcel Blom
Because of some problems with GDAL 1.7.0b2 in FWTools 2.4.7 I upgraded to GDAL 1.11.0 in the latest OSGeo4W distro. This solved some issues I had, but introduced a really annoying one and what ever I do I can't get rid off it. I hope someone can help me out. If BTW I try to go back to GDAL 1.7.

Peter, This is an interesting proof of concept. I have several notes : - not sure about your naming conventions. For me your 'top' and 'bottom' must be inverted. In imaging convention, the y of top is < to the y of bottom - the formula is only appropriate for a resampling up to a factor of 2 - y

[gdal-dev] netCDF: use spatial variables instead dummy dimensions

2014-09-26 Thread klo uo
Hi, I want to convert netCDF dataset to GeoTiff with gdal_translate. My netCDF dataset contains data in projected coordinates, so (x, y) grid dimensions are just dummy enumerated grid values. However dataset contains (lon, lat) spatial mesh variables, matching each (x, y) pair to be able to provid
