Significant New Features
-
Updated datasource to include supported objects up through EPSG v10.094.
-
Added support for two new BYN based transformation methods: "Geographic3D to GravityRelatedHeight (NRCan byn)" and "Vertical Offset by Grid Interpolation (NRCan byn)."
-
Added support for "New Zealand Deformation Model" datum transformations.
-
Added support for new "Similarity Transformation" parametric transformation type.
General
-
Added a more meaningful error when trying to initialize a coordinate transformation that requires a grid file that is unavailable.
-
Added support for new "Lambert (NOAA Port)" and "Lambert (Marta Software)" projection types.
-
Added grid file download for a number of transformations developed for ATKIS (Amtliches Topographisch-Kartographisches Informationssystem [Official Topographic and Cartographic Information System]).
-
Improved logic in both the selection of valid transforms and in the PointTransformer to handle concatenations of vertical transforms that include several height-depth reversals or unit changes.
-
Added optional "XY plane rotation" parameter to the Orthographic projection type.
-
Renamed grid files used for USGEOIS99 transforms to .g99 to avoid confusion with other .bin files
-
Added support for additional OSTN15/OSGM15 coordinate transformations.
Datasource Updates
-
Added Colorado Mesa County Local Coordinate Systems to the datasource.
-
Updated PRJ identifiers in the base datasource to better match ESRI.
-
Added support for "Czech S-JTSK Parametric" parametric transformation type.
-
Added support for new "Hellenic Positioning System" parametric transformation type.
-
Updated point styles on a number of projected coordinate systems to match EPSG.
