Currently if the source raster has no nodata value, the writer will still write nan as the output nodata value, ignoring the flag that specifies if there is a nodata value or not. On a raster with byte data type, this will cause confusion on reading since the nodata value will be somehow cast as 0. Make QgsRasterChecker check for nodata consistency between source and target, and add a test file that shows the issue.
WCS test server installation
----------------------------
WCS test server is based on UMN MapServer running on qgis.org.
1. Install UMN MapServer (mapserver.org) version 6.0 or higher with WCS support (--with-wcs configure option if compiled from source)
2. Copy test data from qgis source tests/testdata/raster somewhere on server, for example to /var/www/data/test/1.9.0/tests/testdata/raster.
3. Edit WCS mapfile, for example /var/www/data/test/1.9.0/tests/testdata/raster/wcs.map and set SHAPEPATH to the path where data were copied, e.g.:
SHAPEPATH "/var/www/data/test/1.9.0/tests/testdata/raster/"
4. Create script in cgi-bin dir where mapfile is specified, e.g. /usr/lib/cgi-bin/wcstest-1.9.0:
#! /bin/sh
MS_MAPFILE=/var/www/data/test/1.9.0/tests/testdata/raster/wcs.map
export MS_MAPFILE
./mapserv
5. Configure Web server, for example if Apache is used, add rewrite rule to config file using /test/<version>/wcs path:
RewriteRule /test/1.9.0/wcs /cgi-bin/wcstest-1.9.0 [PT]
6. WARNING: If possible, don't change WCS server URL for released versions. If the server URL has to be changed for development and future versions, change also the variable TEST_SERVER_URL in tests/src/providers/CMakeLists.txt.
