2019-09-12Coordinate transformation: improve transformations from/to WGS84 (Gxxxx)Even Rouault
Currently very few transformations from/to WGS84 (Gxxxx) are registered in the EPSG database, and there isn't even transformations between WGS84 EPSG:4326 and those ones. Consequently transformations to those realizations often ended up as no-operation, whereas going through WGS84 EPSG:4326 will bring more meaningful results. So register those EPSG:4326<-->WGS 84 (Gxxx) null transformations, and when having WGS 84 (Gxxx) as source/target, consider EPSG:4326 as an intermediate. This change has no effect on the existing direct transformations from/to WGS 84 (Gxxx).

2019-09-12createOperations(): make it work when transforming between CompoundCRS and ↵Even Rouault
Geog3D when the DB has only VertCS to Geog2D This is needed to fix cases that would not work if using the promoteTo3D()/--3d functionnality just added per a6e1d72890615b42f54edad9b17acff8e7623844 In some cases, the EPSG database only contains a Geographic 2D CRS (like NAD83), without a 3D version. Consequently vertical transformations between that Geographic CRS and a Vertical CRS are only available with a 2D CRS code (kind of a bug in modelization by the way...). So when promoting the Geographic 2D CRS to a 3D one, we suddenly cannot find the available transformations any more. So in such situation, try to fallback to the 2D CRS to restore the capability to find the available transformations.

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.

(fixes #1574) The exact circumstances are a bit difficult to explain, but they involve using a non-default context, enabling proj_context_use_proj4_init_rules() on it, using proj_create(ctxt, "+init=epsg:XXXX +type=crs"), whereas PROJ_LIB is defined to a directory that has a 'epsg' file in it.

2019-09-04proj_create_crs_to_crs_from_pj(): make the PJ* arguments const PJ*Even Rouault
This will make the life of C++ users using the C API slightly easier. There's no ABI or API backward compatibility issue in doing that change as constness of arguments is not retained in the C ABI, and any non-const object passed as argument is implicitly converted as a const object if that is what is mentionned in the argument list.

I've been frustrated a number of times with proj_create_crs_to_crs() not accepting a PJ* object for the source and target CRS. And thus constraining to go back to WKT2 in a artificial way.
