Hi List, I have a question about the Mercator Projection's domain of validity.
Checking at this class https://github.com/geotools/geotools/blob/master/modules/library/main/src/main/java/org/geotools/renderer/crs/MercatorHandlerFactory.java#L33 I see that valid latitudes are in the range -85°, +85°. On the EPSG registry definition I see slightly wider bounds: WGS84 bounds: <http://epsg.io/3857> -180.0 -85.06 180.0 85.06 Projected bounds: -20026376.39 -20048966.10 20026376.39 20048966.10 Wikipedia reports something like 85.05. https://en.wikipedia.org/wiki/Mercator_projection GWC GridSet has similar bounds: -20037508.34 -20037508.34 20037508.34 20037508.34 I have a 3857 request slightly above 85°, with yMin, yMax = (*1999*8372, *2003*7508) which theoretically intersects the definition range of 3857. However that -85,+85 valid area bounds definition returns an empty intersection since (-85,+85) correspond to (-19971869, *1997*1869) which is below my request. Should we increase that valid area bounds to -85.06, 85.06? Or do these rounded -85,85 have been set to cover some more cases or variants which I'm not familiar with and 85.06 is only valid for 3857? -- Regards, Daniele Romagnoli == GeoServer Professional Services from the experts!
