Currently when we project geometries, we are projecting the coordinates = one by one. When data is outside the valid range of a map projection (or cr= osses a map boundary), invalid geometries are created.=20
Use the valid area of a map projection to "clip" the geometrie= s before they are transformed.=20
A mercator projection is not valid at the poles and the map boundary is = +- 180 degrees from the central meridian.=20
An exploration of this issue is being done by rschulz (stuck in the midd= le of the bush during May) as a demo. The demo is completely separate from = geotools (does not modify geotools code).=20
I will stick the demo in svn once it works and place a list of thoughts/= issues here.
