Re: [udig-devel] Udig problem reading sample values of geotiff
|
I think you may of answered your own question? The image provided by uDig is a rendered image; it may of been processed a bit prior to you getting it. As an example the values may represent a measurement; rather than simply RGB values...
We may need to take your example to the geoTools list; do you mind trying with the GeoTools GeoTIFF reader and seeing what you get?

and I obtain the
correct values for example 4.0
When I change the
raster image read on filesystem, with the rendered image obtained by udig
raster layer, I obtain different values. For example in the pixel with
value 4.0 I found 1.512366E38.
Where is the
problem?
How can I solve
it?
