2020-02-06Fix identification of ESRI-style datum names starting with D_ but without aliasEven Rouault
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.

(fixes #1801) Fix for ``` projinfo --identify "+proj=utm +zone=48 +a=6377276.345 +b=6356075.41314024 +towgs84=198,881,317,0,0,0,0 +units=m +no_defs +type=crs" ``` to only return BoundCRS of EPSG:3148: 70 % Previously it also returned EPSG:23948 and EPSG:24048 whose projected CRS-only parts where likely matches, but those 2 CRSs don't have a +towgs84=198,881,317,0,0,0,0, so discard them.

2019-11-25normalizeForVisualization() and other methods applying on a ProjectedCRS: do ↵Even Rouault
not mess the derivingConversion object of the original object (fixes #1736) normalizeForVisualization(), promoteTo3D(), demoteTo2D(), alterGeodeticCRS(), alterCSLinearUnit() and alterParametersLinearUnit() all used the object returned by derivingConversionRef() to create a new ProjectedCRS. While doing so, this caused the derivingConversion of the original object to have its targetCRS set to the object returned by normalizeForVisualization() and similar. If that object died, then the weak pointer would be reset, and the original ProjectedCRS() has now its derivingConversionRef()->targetCRS() nullptr So bottom line is use derivingConversion() for anything that is not pure reading !!! This is confirmed to be the fix for the QGIS scenario in https://github.com/qgis/QGIS/issues/30569#issuecomment-540060919 In QGIS use case, the issue arised when using a projected CRS with a non-GIS friendly axis (that is where normalizeForVisualization() created a new projectedCRS)
