GeoTiff plugin's GeoTiffMetadata2CRSAdapter.getRasterToModel method doesn't
correctly handle ModelTransformationTag + RasterTypeGeoKey
---------------------------------------------------------------------------------------------------------------------------------------
Key: GEOT-2058
URL: http://jira.codehaus.org/browse/GEOT-2058
Project: GeoTools
Issue Type: Bug
Components: gc geotiff
Affects Versions: 2.5.0, 2.4.5
Reporter: Daniele Romagnoli
Assignee: Daniele Romagnoli
Fix For: 2.4.6, 2.5.1
The GeoTiffMetadata2CRSAdapter.getRasterToModel method doesn't correctly handle
the ModelTransformationTag.
In case the rasterType is RasterPixelIsArea (meaning PixelInCell#CELL_CORNER)
the transformation should be converted to a PixelInCell#CELL_CENTER since the
Javadoc says that the method creates the raster to model transformation
repsecting ALWAYS the OGC PixelInCell#CELL_CENTER convention.
Moreover, in case the rasterType is RasterPixelIsPoint (meaning
PixelInCell#CELL_CENTER) the additional half-pixel translate shouldn't be added.
Then, the half-pixel translation code should be moved from the "if (rasterType
== GeoTiffConstants.RasterPixelIsPoint)" branch to the
"if (rasterType == GeoTiffConstants.RasterPixelIsArea)" one.
