This could likely be fixed in jai-ext. Another possible approach would be to "fix" image mosaic so that it does not generate these huge coordinates to start with. Right now it's using a global "grid to world" to represent the output, but I believe it could be using a "reduced" one, local to the requested area, that would position images in raster space location closer to the origin, and thus avoid this issue without causing performance regressions. Just an idea ;-) Cheers Andrea -- == GeoServer Professional Services from the experts! Visit http://goo.gl/it488V for more information. == Ing. Andrea Aime @geowolf Technical Lead GeoSolutions S.A.S.
