Hi, I'm trying to fix an issue we have in GeoServer related to map reprojection and... I've found a solution, but not sure people will like it.
The issue is here: http://jira.codehaus.org/browse/GEOS-1804 Basically, we have a client that is asking to render a map in the Google projection, and using the following bbox: -31308606.78125,-23481455.0859375,31308606.78125,23481455.0859375 which is way out of the 900913 bounds, which are: -20037508.34,-20037508.34,20037508.34,20037508.34 Now, the renderer takes the bbox in the request and tries to reproject it back in the native srs of the data, in this case, 4326, and trips over a referencing exception, complaining that: org.geotools.referencing.operation.projection.PointOutsideEnvelopeException: Longitude 281°15.0'W is out of range (±180°). at org.geotools.referencing.operation.projection.MapProjection$Inverse.transform(MapProjection.java:931) at org.geotools.referencing.operation.projection.MapProjection$Inverse.transform(MapProjection.java:973) at org.geotools.referencing.operation.transform.AbstractMathTransform.transform(AbstractMathTransform.java:217) at org.geotools.referencing.CRS.transform(CRS.java:983) at org.geotools.referencing.CRS.transform(CRS.java:1046) at org.geotools.geometry.jts.ReferencedEnvelope.transform(ReferencedEnvelope.java:465) Now, that longitude is in fact way out of range, but most WMS client do not have a knowledge of what the proper bounds are for a projection. It seems to me that it would be better to turn those exceptions into assertions, that is, make them trigger only someone really asked for detailed sanity checks. I tried to comment out line 930-937 of MapProjection, and as a result GeoServer is now able to render my map properly even when the bbox is out of the valid area. Opinions? A bit more leniency allows projection unaware clients to work better.
