Hi,
in the context of georchestra, using geoserver 2.1.3/geotools 2.7.4 and
geosource trunk with tomcat 6 i'm trying to make the geopublish feature
from geosource to push ecw files (through REST) to geoserver. I've fixed
various issues on the geosource/geonetwork side, but i'm facing a
usecase that puzzles me:
- manually uploading the ecw/prj file to geoserver dir, and creating an
ecw store from it works fine. The layer projection is correctly taken
from the .prj file.
- uploading a zip containing a geotiff file correctly creates a tiff
store with a correct projection
- uploading a zip (via REST/geosource) containing an ecw file (along
correctly named .eww/.prj files) creates an ecw store, but the
projection is not set. (I've also tried with .ecw.aux and .ecw.aux.xml
files..) I've added some debug code to
src/restconfig/src/main/java/org/geoserver/catalog/rest/CoverageStoreFileResource.java:165
LOGGER.info(" coverage store " + coveragestore + " has CRS " +
cinfo.getSRS());
which gives me in the log :
INFO [catalog.rest] - coverage store 7147-64377 has CRS null
so the determined CRS is not even UNKNOWN, just unset. To 'fix' it i
need to go into geosource on the layer page and manually force the
declared CRS, but this is not an option for my end users who should just
see the geopublishing from geosource. I'm also confused by the CRS/SRS
difference..
Btw, i have the tomcat 6 fix for imageio/ecw mentioned in
http://jira.codehaus.org/browse/GEOS-4994 - this works fine for manually
configured ecw stores.
several questions :
- did anyone try to REST-upload a zip containing an ecw file and got a
correctly detected layer projection ? To me it's impossible to embed the
projection directly in the ecw file so we need additional files for that..
- where should i add debug configuration to pinpoint where the
projection is read, and from which file ? From my understanding for ecw
files this is done in geotools.. or in imageio-ext (maybe
geotools/modules/plugin/imageio-ext-gdal/src/main/java/org/geotools/coverageio/gdal/)
? Using strace, i've seen geoserver looking for .eww, .hdr, .prj and
.aux. It's not really obvious how should i proceed to make geotools more
verbose inside geoserver..
- what additional informations should i provide to debug this issue ?
Thanks!
