Snow Nyall Dawson Chris Mayo Mike Taves Kristian Evers Even Rouault 6.0.0 Release Notes ------------------- PROJ 6 has undergone extensive changes to increase its functional scope from a cartographic projection engine with so-called "early-binding" geodetic datum transformation capabilities to a more complete library supporting coordinate transformations and coordinate reference systems. As a foundation for other enhancements, PROJ now includes a C++ implementation of the modelisation propopsed by the ISO-19111:2019 standard / OGC Abstract Specification Topic 2: "Referencing By Coordinates", for geodetic reference frames (datums), coordinate reference systems and coordinate operations. Construction and query of those geodetic objects is available through a new C++ API, and also accessible for the most part from bindings in the C API. Those geodetic objects can be imported and exported from and into the OGC Well-Known Text format (WKT) in its different variants: ESRI WKT, GDAL WKT 1, WKT2:2015 (ISO 19162:2015) and WKT2:2018 (ISO 19162:2018). Import and export of CRS objects from and into PROJ strings is also supported. This functionality was previously available in the GDAL software library (except WKT2 support which is a new feature), and is now an integral part of PROJ. A unified database of geodetic objects, coordinate reference systems and their metadata, and coordinate operations between those CRS is now available in a SQLite3 database file, proj.db. This includes definitions imported from the IOGP EPSG dataset (v9.6.0 release), the IGNF (French national mapping agency) geodetic registry and the ESRI projection engine database. PROJ is now the reference software in the "OSGeo C stack" for this CRS and coordinate operation database, whereas previously this functionality was spread over PROJ, GDAL and libgeotiff, and used CSV or other adhoc text-based formats. Late-binding coordinate operation capabilities, that takes metadata such as area of use and accuracy into account, has been added. This can avoid in a number of situations the past requirement of using WGS84 as a pivot system, which could cause unneeded accuracy loss, or was not doable at all sometimes when transformation to WGS84 was not available. Those late-binding capabilities are now used by the proj_create_crs_to_crs() function and the cs2cs utility. A new command line utility, projinfo, has been added to query information about a geodetic object of the database, import and export geodetic objects from/into WKT and PROJ strings, and display coordinate operations available between two CRSs. UPDATES ------- o Removed projects.h as a public interface (#835) o Deprecated the proj_api.h interface. The header file is still available but will be removed with the next major version release of PROJ.

The main driver for introducing the new features is the emergence of dynamic reference frames, the increasing use of high accuracy GNSS, and the related growing demand for accurate coordinate transformations. While older versions of PROJ included some geodetic functionality, the new framework lays the foundation for turning PROJ into a generic geospatial coordinate transformation engine. The core of the library is still the well established projection code. The new functionality is primarily exposed in a new programming interface and a new command line utility, "cct" (for "Coordinate Conversion and Transformation"). The old programming interface is still available and can - to some extent - use the new geodetic transformation features. The internal architecture has also seen many changes and much improvement. So far, these improvements respect the existing programming interface. But the process has revealed a need to simplify and reduce the code base, in order to support sustained active development. !!! !!! Therefore we have scheduled regular releases over the coming years !!! which will gradually remove the old programming interface. !!! !!! This will cause breaking changes with the next two major version !!! releases, which will affect all projects that depend on PROJ !!! (cf. section "deprecations" below). !!! The decision to break the existing API has not been easy, but has ultimately been deemed necessary to ensure the long term survival of the project. Not only by improving the maintainability immensely, but also by extending the potential user (and hence developer) community. The end goal is to deliver a generic coordinate transformation software package with a clean and concise code base appealing to both users and developers. VERSIONING AND NAMING --------------------- For the first time in more than 25 years the major version number of the software is changed. The decision to do this is based on the many new features and new API. While backwards compatibility remains - except in a few rare corner cases - the addition of a new and improved programming interface warrants a new major release. The new major version number unfortunately leaves the project in a bit of a conundrum regarding the name. For the majority of the life-time of the product it has been known as PROJ.4, but since we have now reached version 5 the name is no longer aligned with the version number. Hence we have decided to decouple the name from the version number and from this version and onwards the product will simply be called PROJ. In recognition of the history of the software we are keeping PROJ.4 as the *name of the organizing project*. The same project team also produces the datum-grid package. In summary: o The PROJ.4 project provides the product PROJ, which is now at version 5.0.0. o The foundational component of PROJ is the library libproj. o Other PROJ components include the application proj, which provides a command line interface to libproj. o The PROJ.4 project also distributes the datum-grid package, which at the time of writing is at version 1.6.0. UPDATES ------- o Introduced new API in proj.h. - The new API is orthogonal to the existing proj_api.h API and the internally used projects.h API. - The new API adds the ability to transform spatiotemporal (4D) coordinates. - Functions in the new API use the "proj_" namespace. - Data types in the new API use the "PJ_" namespace, with a few historic exceptions such as XY, XYZ, LP and LPZ. o Introduced the concept of "transformation pipelines" that makes it possible to do complex geodetic transformations of spatiotemporal coordinates by daisy chaining simple coordinate operations. o Introduced cct, the Coordinate Conversion and Transformation application. o Introduced gie, the Geospatial Integrity Investigation Environment. - Selftest invoked by -C flag in proj has been removed - Ported approx. 1300 built-in selftests to gie format - Ported approx. 1000 tests from the gigs test framework - Added approx. 200 new tests o Adopted terminology from the OGC/ISO-19100 geospatial standards series. Key definitions are: - At the most generic level, a *coordinate operation* is a change of coordinates, based on a one-to-one relationship, from one coordinate reference system to another. - A *transformation* is a coordinate operation in which the two coordinate reference systems are based on different datums, e.g. a change from a global reference frame to a regional frame. - A *conversion* is a coordinate operation in which both coordinate reference systems are based on the same datum, e.g. change of units of coordinates. - A *projection* is a coordinate conversion from an ellipsoidal coordinate system to a plane. Although projections are simply conversions according to the standard, they are treated as separate entities in PROJ as they make up the vast majority of operations in the library. o New operations: - The pipeline operator (pipeline) - Transformations: + Helmert transform (helmert) + Horner real and complex polynomial evaluation (horner) + Horizontal gridshift (hgridshift) + Vertical gridshift (vgridshift) + Molodensky transform (molodensky) + Kinematic gridshift with deformation model (deformation) - Conversions: + Unit conversion (unitconvert) + Axis swap (axisswap) - Projections: + Central Conic projection (ccon) o Significant documentation updates, including - Overhaul of the structure of the documentation - A better introduction to the use of PROJ - A complete reference to the new proj.h API - a complete rewrite of the section on geodesic calculations - Figures for all projections o New "free format" option for operation definitions, which permits separating tokens by whitespace when specifying key/value- pairs, e.g. "proj = merc lat_0 = 45". o Added metadata to init-files that can be read with the proj_init_info() function in the new proj.h API. o Added ITRF2000, ITRF2008 and ITRF2014 init-files with ITRF transformation parameters, including plate motion model parameters. o Added ellipsoid parameters for GSK2011, PZ90 and "danish". The latter is similar to the already supported andrae ellipsoid, but has a slightly different semimajor axis. o Added Copenhagen prime meridian. o Updated EPSG database to version 9.2.0. o Geodesic library updated to version 1.49.2-c. o Support for analytical partial derivatives has been removed. o Improved performance in Winkel Tripel and Aitoff. o Introduced pj_has_inverse() function to proj_api.h. Checks if an operation has an inverse. Use this instead of checking whether P->inv exists, since that can no longer be relied on. o ABI version number updated to 13:0:0. o Removed support for Windows CE. o Removed the VB6 COM interface.

This change may only be temporary till a more comprehensive solution is found. o Fixed handling of extra text in cs2cs. o Renamed INSTALL to INSTALL.TXT. o The eqc projection has been generalized to include a latitude of origin. o Added the glabsgm (Gauss Laborde / Sphere Geometric Mean) projection, and gstmerc variation. o nad/IGNF init catalogue created. o added the ntf_r93.gsb datum shift file. o Add /Op in nmake.opt compile options to avoid VC7 optimization bug (#12) o Fix testvarious test script so it works properly when grid files available 4.6.0 Release Notes ------------------- o MAJOR: Rework pj_transform() to avoid applying ellipsoid to ellipsoid transformations as a datum shift when no datum info is available. o Avoid applying "change of ellipsoid" during datum shifting based on ellipsoids getting changed to spheres for spherical projections. o Upgrade to EPSG 6.13 o Added "900913" "Google Mercator" code in nad/esri.extra. o Avoid some static variable based multi-threading problems. o Improve error recovery if ctable style datum shift grid fails to load. o Support drive letters properly in PROJ_LIB paths for win32. o Fix occasional problem with DMS parsing. o Removed non-functional mpoly projection. o add lonlat, and latlon as aliases for longlat. 4.5.0 Release Notes ------------------- o Microsoft Visual Studio 8 compatibility changes. o Upgraded to EPSG 6.11.1 database. o Several bug fixes to pj_transform() to handle transient errors properly. o Fix Krovak projection (include +czech flag) o Added Roussilhe Stereographic projection from libproj4 (proj=rouss). o Added experimental +lon_wrap flag for alternate pj_transform() longitude wrapping behavior on output. 4.4.9 Release Notes ------------------- o Win32 build uses proj.dll by default now. o Added accessor functions for the datums, ellps, prime_meridians, units and main projection definition lists so they can be used on windows where data objects exported from the DLL don't work easily. o Added JNI (Java Native Interface) support within the jniwrap directory, and some supporting entry points directly in the proj dll/so. See --with-jni configure switch, and jniwrap/README. o Added the proj=stereoa and proj=geos projections, incorporated from Gerald's libproj4. o A few other bug fixes. 4.4.8 Release Notes ------------------- o Updated epsg file to EPSG 6.5, added other.extra pseudo-EPSG WMS definitions o Made significant fixes to prime meridian support. o Substantially change pj_datum_transform(), so it and pj_transform() will work between coordinate systems with different ellipsoids but no datum shift information (assume +towgs84=0,0,0). o Added pj_get_release() function. o Ensure pj_transform() will try to transform all points in provided list if even some might transform properly. o Improved the accuracy of Geocentric_To_Geodetic() via an iterative solution. o Various other bug fixes. 4.4.7 Release Notes ------------------- o Added NTv2 (.gsb) grid shift file support. o Modified datum shift support so that data file data is only loaded if needed. Also added 'null' grid as a fallback option, and support for making grids optional (prefix with '@' in +nadgrids). o Regenerated nad/epsg file with towgs84 parameters for non-greenwich prime meridians. o Updated nad/esri file with better generated form from Paul Ramsey. o Various bug fixes. 4.4.6 Release Notes ------------------- o Incorporated new lcca (Lambert Conformal Conic Alternate) projection from Gerald. o Updated 'espg' translation file for EPSG 6.2.2 with better support for prime meridians. o Added Prime Meridians via +pm command switch to cs2cs (and pj_transform). o Fixed bug with 7 parameter transforms. o Added 'esri' pseudo-epsg coordinate system file. o Cleanup so that PROJ.4 compiles clean as C++ code. o Added pj_get_def() to expand definitions of stuff like +init clauses. o Added a Krovak implementation (proj=krov). Note this may change again in the next release.
