[SOLVED] Raster Data Types

[Sokolowski]

Folks,

Just wondering if there are limitations to the data types QGIS can ingest as raster. I'm doing a hyperspectral projecect with various other imagery and I've got some 4-byte floats, 2-byte integer, 2-byte unsigned integer and some of them end up importing as raster layers showing up as solid gray. I wonder if this is a data type problem w/ QGIS. I can scale to byte, or any other data type, but of course end up distorting scale and loosing resolution.

Thanx

QGIS uses GDAL/OGR to access all kinds of raster data. To find out limitations, better check their pages. Personally, I haven't encountered any troubles like you describe.

Turns out in the "properties" for the raster layer, one can set the data limits. There are convenient settings like "min - max" which properly scales the data nicely. Sorry for the premature post... but thanks for the quick turn-around and reply...
