Fix a few issues of #1906 found when running the test suite on Ubuntu 16.04 with gcc 5.5 -m32. When applied on top of the fix of #1912, make check succeeds
2020-02-08cart: Avoid discontinuity at poles in the inverse caseKristian Evers
This should avoid issues with numerical stability as uncovered in https://github.com/OSGeo/PROJ/issues/1906. Practically speaking this change isn't going to affect real life scenarios since the position of the center of the Earth is rarely expressed in geodetic coordinates.

Fixes #1911
2020-02-06Fix performance issue, affecting projinfo EPSG:7842Even Rouault
Fixes #1913 AuthorityFactory::createBetweenGeodeticCRSWithDatumBasedIntermediates() issued a complex SQL query that pushes the SQLite3 query plan optimizer to its limits. Was working reasonably with sqlite 3.11, but not with later versions. So put less constraints in the main query and do post-processing checks and auxiliary requests to avoid such issues. For some unknown reason, this slightly slows down a bit execution time of the whole test_cpp_api binary (~ 10%), but couldn't come with something better, despite trying many variations of the main SQL query. It seems that in the general case the non-filter LEFT JOIN on the supersession table helped, except on this EPSG:7842 case.
2020-02-06Fix ingestion of +proj=cea with +k_0Even Rouault
Fixes #1881 Digging into the implementation of proj=cea, it appears that k_0 and lat_ts are intended to be exclusive ways of specifying the same concept. EPSG only models the variant using lat_s. So if k_0 is found and lat_ts is absent, compute the equivalent value of lat_ts from k_0. Note: k_0 should normally be in the [0,1] range. In case creative users would use something outside, we raise an exception, even if the cea implementation could potentially deal with any k_0 value. Hopefully this is a (reasonable) limitation that will address nominal use cases.

2020-01-23Fix wrong use of derivingConversionRef() that caused GDAL bugEven Rouault
Hopefully final cut at solving the same class of bug that the one that affected QGIS in December. This time, this hit GDAL in the situation of https://lists.osgeo.org/pipermail/gdal-dev/2020-January/051500.html The bug fix for that particular issue is in PROJStringParser::createFromPROJString() But grepping more in the code base, I could find other potential smelly situations (might not be issues, but better be safe than sorry), so let's fix them too. Bottom line is: derivingConversionRef() should *only* be used for consultation, and never to create a new ProjectedCRS()

Not certain whether this is appropriate when you are dealing with lists of grids, but it definitely helps for a single grid.

Explain why sweep axis affects geolocation
2020-01-16Explain why sweep axis affects geolocationGerrit Holl
In the note on the sweep angle, add a line explaining why the sweep angle ultimately affects the geolocation, as it is not immediately or trivially obvious to see why it should matter what the outer or inner gimbal is. To this end, link to a post on Mathematics Stack Exchange that explains this very well.
