Dear list,
I discovered a strange behavior using the ImageMosaic Plugin. I could
successfully create the imagemosaic stores using the REST interface. But when
extending the store with new data using the external.imagemosaic function, some
mosaic stores were not updated.
I could identify some difference in the data: If I want to use data that are
converted before with the gdal_translate -co NBITS=1 command, the geoserver
throws an error: WARN [gce.imagemosaic] - Failure occurred while collecting the
granules. See error message below. It works fine when I do not convert the
data! The imagemosaic store creation works fine for both. Just updating is not
possible when data are converted before.
The relevant gdalinfo differences are listed here (first file the not converted
data, second file the NBITS=1 converted data):
< Band 1 Block=17393x1 Type=Byte, ColorInterp=Gray
---
> Band 1 Block=17393x3 Type=Byte, ColorInterp=Palette
32a34,38
> Image Structure Metadata:
> NBITS=1
> Color Table (RGB with 2 entries)
> 0: 0,0,0,255
> 1: 255,255,255,255
Is this a known problem or can you provide any quick solution for that?
Thanks,
Jonas
