hello grass members, i am no specialist in gis-software-usage and file fomrat coneversion. but for a project in 3d i have the files from this website (http://deepreef.org/bathymetry/65-3dgbr-bathy.html) you find the GMT/netCDF bathymetry grid [zip] 1.1 GBytes which is a 32bit geotiff with the necessary bathymetry hights. i need thise file to be concerted to a 16 bit file for the usage in e.g. cinema4d which can only read 16nit files. but the problem is, that i do not no how to convert it with the right grass export adjustments so the tiff file keeps it's constant black to white gradient.
i always end up with a 16 bit file which is shaded from the origin of 0 meters hight. that meens thet for every value above 0 the shadiong is from black to grey for higher values but for every hight below 0 the gradient range will start from white to gray so ther is a sharp cut at 0 meters and not like the greyscale you see on the webpage. does anybody know how this tiff could be converted to a regual grayscale starting from black (minimal hight) to white (maximal height?) thank you, ixtract -- View this message in context: http://osgeo-org.1803224.n2.nabble.com/Convert-32bit-geotiff-to-a-16bit-tiff-file-tp5791303p5791303.html Sent from the Grass - Users mailing list archive at Nabble.com. _______________________________________________ grass-user mailing list [email protected] http://lists.osgeo.org/mailman/listinfo/grass-user
