PROJ/include/proj, branch 6.2

normalizeForVisualization() and other methods applying on a ProjectedCRS: do not mess the derivingConversion object of the original object (fixes #1736)

2019-11-25T12:14:35+00:00

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)

API: add CRS::promoteTo3D(), proj_crs_promote_to_3D() and proj_crs_create_projected_3D_crs_from_2D() (fixes #1587)

2019-09-15T16:39:07+00:00

(projinfo changes adding --3d from master removed)

createOperations(): fix pipeline generation when a CRS has terms like +datum=NAD27 and +over, where the datum was just replaced by its ellipsoid

2019-08-26T16:12:38+00:00

C API: add proj_context_set_autoclose_database() to automatically close database (fixes #1565)

2019-08-20T11:26:54+00:00

PROJJSON: rename file as projjson.schema.json, and add versionning to it and to exported PROJJSON strings
