2019-09-11createOperations(): fix conversion from/to PROJ.4 CRS strings with ↵Even Rouault
non-ISO-cosher options and towgs84/nadgrids This actually fixes a regression introduced in PROJ 6.2.0 per 78302efb70eb4b49610cda6a60bf9ce39b82264f that made a conversion like EPSG:4326 to "+proj=something +towgs84/+nadgrids +over +type=crs" apply the towgs84/nadgrids operation twice.
2019-09-08Use in API and utilities WKT2_2019 instead of WKT2_2018 (fixes #1518)Even Rouault
- C API: PJ_GUESSED_WKT2_2019 is added, PJ_GUESSED_WKT2_2018 aliased to it - C API: PJ_WKT2_2019[_SIMPLIFIED] is added, PJ_WKT2_2018[_SIMPLIFIED] alias to it - C++ API: similarly for WKTFormatter::Convention::WKT2_2019[_SIMPLIFIED] Those above changes should be fully backward API and ABI compatible. projinfo changes: - accept WKT2_2019 as value for -o switch. WKT2_2018 is still accepted (undocumented) - output now uses 'WKT2_2019 string:', so might break scripts that would rely on that. Other internal code references to WKT2_2018 changes to WKT2_2019, included in tests.

2019-03-29Add proj_normalize_for_visualization()Even Rouault
Fixes #1301 This function takes the output PJ from proj_create_crs_to_crs(), and add (or undo) the needed axis swap operations so that the object returned by proj_normalize_for_visualization() has the usual GIS axis order. In this implementation, this does something only if the coordinate system of the source or target CRS, geographic or projected, has NORTH, EAST ordering. CompoundCRS wrapping those objects are also handled.

Fixes #1388 Typically helps for projinfo -s "+proj=longlat +ellps=GRS80 +towgs84=1,2,3 +type=crs" -t EPSG:4258 by researching operations from the pivot WGS84 implied by the towgs84 clause to EPSG:4258.

2019-02-11Make tmerc an alias for etmerc. (#1234)Kristian Evers
* Make tmerc an alias for etmerc This switches the algorithm used in tmerc to the Poder/Engsager tmerc algorithm. The original tmerc algorithm of Evenden/Snyder origin can still be accessed by adding the +approx flag when initializing a tmerc projection. The +approx flag can also be used when initializing UTM projections, in which case the Evenden/Snyder algorithm is used as well. If a tmerc projection is instantiated on a spherical earth the Evenden/Snyder algorithm is used as well since the Poder/Engsager algorithm is only defined on the ellipsoid. +proj=etmerc can still be instantiated for backwards compatibility reasons.

2019-01-08ISO19111: remove PROJ.5 specific format for CRS (refs #1214)Even Rouault
As discussed in https://github.com/OSGeo/proj.4/issues/1214#issuecomment-452084720, the introduction of a new PROJ.5 format to export CRS using pipeline/unitconvert/axisswap as an attempt of improving the PROJ.4 format used by GDAL and other products is likely a dead-end since it is still lossy in many aspects and can cause confusion with coodinate operations. Consequently the PROJ_5 convention will be identical to PROJ_4 for CRS export. Note: on the import side, I've kept the code that could parse unitconvert and axisswap when building a CRS definition from a pipeline. It is there as a hidden feature as it was kind of a tear to remove that code in case it might still be useful...
