I would appreciate some ideas here. I have the need of creating thousands of maps with based on the same CRS but with changes in latitude_of_origin and central_meridian and, for that matter,I do the following:
- Take a base CRS definition in WKT form. - Set the parameters I need. - Create the CRS using using CRS.parseWKT. The whole process is like this: - Get the new latitude_of_origin and central_meridian. - Create a new CRS using the method described above. - Create a new MapContent and set the target CRS with the one I just created. - Add shape layers. - Build a final image using StreamingRenderer. Performance wise, the above process gives excellent results when using the same target CRS for every request. However, when changing the CRS for each new set of coordinates the rendering process takes longer and longer until after 40,000 transformations it is taking about 10 times the time it was taking originally per rendering. It makes me think that some problem accumulates when switching CRSs or maybe my workflow is all wrong. Any suggestions or ideas would be very much appreciated.
