GeoTools is a GIS toolkit that is used for OGC-based projects via GeoAPI interfaces. It includes two great SLD based renderers and tools for raster access and reprojection as well as plugins for Shapefile, ArcGrid, ArcSDE, Postgis, OracleSpatial, MySQL, and many more.Changes: This is a bugfix release made in conjunction with uDig 1. 2-RC3. It adds support for Oracle Georaster access and many small but interesting improvements, including interpolate functions which are very useful when styling maps. Generated SLD files no longer write out "default" values, which will make for a more readable result.
