As proposed in yesterday IRC, there is an update of progress in port of GeoTools 2.x code to Geotidy. On a related note, I think that the amount of changes in geotidy looks scary. But in the case of the referencing module, if you didn't wrote your own MapProjection classes, I think that you are likely to be unaffected.
In the list below, [X] are done and [ ] remain to be done. This is all port from GeoTools 2.x, with some issues fixed with new code. [X] Utilities except the caching classes. [ ] Caching classes (used by threaded EPSG factories) [X] Metadata except the connection to SQL database [ ] Metadata on SQL database (should be a separated module) [X] Parameters (org.opengis.parameter) [X] Basic referencing objects (org.opengis.cs|crs|datum) [X] Referencing objects factories (not authority factories) [ ] Basic authority factories [ ] EPSG factories [X] Basic math transforms [ ] Map projections [ ] Referencing 3D Right now I'm on MapProjection. For those who may be interrested, I'm tuned two steps that were previously implicit (the normalization to an ellipse of semi-major axis length of 1) as explicit AffineTransform. See "Projection on unit sphere" here: http://geotidy.geomatys.fr/apidocs/org/geotools/referencing/operation/projection/package-summary.html I wanted to do that for a long time since it allows more efficient concatenation of (inverse projection, projection) in some cases. But the even that trigged this work is the following issue discussed on the mailing list, which can be better solved with explicit affine transform: http://n2.nabble.com/ESRI-Axis-definition-issue-td783580.html Martin ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Geotools-devel mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/geotools-devel
