Im importing some geotiff rgb rasters into spatialite via rasterlite_load utility. During the load i get a warning that some of the tiles are not geotiffs (but they are, they all load normaly if loaded as standalone raster files into qgis or arcgis), but the procedure finishes anyway. I can then add the sqlite base as a raster layer into qgis but those files are rendererd black. Wird thing is, when i zoom in/out some parts that previously didnt render then render, but never entirely the way they should. Anyone else stumbled upon this?

I also tried with tif+tfw world file, but the result is the same.

Update: No matter what i tried those two geotiffs wouldn't be accepted via rasterlite_load utility. I even tried converting them to jpeg and back to geotiff, and i tried a million other things including creating them on my windows machine, nothing worked. In the end, i created the geotifs with Erdas Imagine, now that worked! Which means there's maybe an issue in GDAL library (qgis uses gdal when translating raster formats). I ll probably explore further at some point

Its hard to day, since you've missed a lot of valuable information. Version of spatialite and rasterlite? Import process (exact steps)? Sample data that reproduces the problem? Results in spatialite tools? Screenshot of the the actual rendering results? – BradHards Sep 2 '12 at 0:27
Yes i know, i just thought if it was an obvious issue many people encountered before someone would just spit the obvious answer ;) i ll post more information a bit later. – U2ros Sep 2 '12 at 6:43
Okay, i think i figured it. 2 original tiles were currupted somehow, the 2 warnings that came up during loading process were actually about the files '.' and '..' which can be discarded of course. – U2ros Sep 2 '12 at 7:35
Try using tiffinfo (from libtiff) to dump the metadata from those tiffs. – BradHards Sep 2 '12 at 20:51
