Hi,
I am currently using MosaicIndexBuilder to create one gridCoverage from
different geotiffs.
It's working QUITE fine, but sometimes, I get this exception during zoom or
pan :
java.lang.NullPointerException

Another problem is that sometimes, I have some white bands (holes) one my
map.
Does anyone get an idea about this ?
Thanks
Thomas
