[Geoserver-users] Geotiff image appears black on map preview

Claudiomir_Zanchetti · January 12, 2009, 2:26am

Hi,

I have a raster tiff image (from ENVI) with .tfw file.
I used the gdal_translate command to translate the tiff image to geotiff,
where the results are below:

Hi!

No clue of what could be happen? I really don't understand, with another
geotiff image, like the "sample.tif" used in the tutorials of Geoserver,
works fine.
The size of this image is around 50 MB.

Any help is welcome.

Thanks!

Ciao Claudio,
I played a little bit with your image and as I suspected, there are no
particular problems with it, it appears to be all black just because
it badly occupies his own dynamic.
The image has 3 bands, 16 bits each, but the dynamic is highly
compressed towards zero, which makes the image looks like all dark.

As an instance, I have posted here (http://pastebin.com/f2c9b6d4c)
some code here which I borrowed from another project where I was doing
contrast stretch on a 16 bits geotiff to bring it back to 8 bits. The
final image is a bit better (less compressed dynamic) but I suspect
that something more elaborate might be needed (some good old
brightnees and contrast enhancement).

Ciao,
Simone.

Hi to all...

Only for record, this problem was successful solved

The representation of the image (in the map properties of ENVY system) had
"Unsigned Integer", I just change this property to "Integer".

Thank you all for attention, and special Thanks to Simone Giannecchini for
help.

Cheers,
Claudiomir Zanchetti (Caio)
