There's a mismatch between ArcSDE Raster's spatial extent and grid envelope
producing inaccurate coverages
----------------------------------------------------------------------------------------------------------
Key: GEOT-3358
URL: http://jira.codehaus.org/browse/GEOT-3358
Project: GeoTools
Issue Type: Bug
Components: data arcsde
Affects Versions: 2.7-M5, 2.6.5
Reporter: Gabriel Roldán
Assignee: Gabriel Roldán
Fix For: 2.6.6, 2.7-beta1
There's an error on how the arcsde module calculates the spatial bounding box
of coverages. It takes the arcsde reported bbox for rasters as tied to pixel
corners, while it's actually tied to pixel centers. So the resulting bounding
box is a bit off and overlaid images extracted of the same raster do not
exactly match. The effect is most visible at higher resolutions, the closer to
the original raster resolution the image is, and is appreciable by a quarter to
half pixel mismatch.
