2019-09-26Improve vertical transformation supportEven Rouault
When we had a transformation between a compoundCRS and a target geographicCRS, we did not take into account that in the vertical->other_geog_CRS transformation we used, the other_geog_CRS was an implicit interpolation CRS. Thus before doing vertical adjustment, we must go to this interpolation CRS. The workflow is thus: source CRS -> interpolation CRS + vertical adjustment + interplation CRS -> target CRS
2019-09-26proj_create_crs_to_crs(): fix when there are only transformations with ↵Even Rouault
ballpark steps Currently we would discard all operations, resulting in a PJ object with zero candidates. Better use those operations if nothing better is available. Was seen on transforming from ETRS89 / UTM zone 31N + EGM96 height to WGS 84 (G1762). The horizontal transformation from ETRS89 to WGS 84 (G1762) is a ballpark one.

2019-09-22Update to version 1.50 of the geodesic library.Charles Karney
* Allow arbitrarily complex polygons in geod_polygon_*. In the case of self-intersecting polygons the area is accumulated "algebraically", e.g., the areas of the 2 loops in a figure-8 polygon will partially cancel. * Simplify code by using C99 functions remainder and remquo. * More test coverage. Fixes to associated files: * src/pipeline.cpp invoke geod_init with f = es / (1 + sqrt(1 - es)) instead of (the less accurate) f = 1 - sqrt(1 - es) * src/apps/geod_set.cpp remove "#undef f" (a dangling relic?).
2019-09-19Require C99 compiler see #1621Charles Karney
cmake and autoconf now stipulate C99 change c89 to c99 in travis jobs remove HAVE_C99_MATH checks (unrelated) relax Visual Studio compatibility check in cmake/project-config-version.cmake.in (VS 2019 can use a VS 2015 library but not vice versa).
2019-09-19Merge pull request #1618 from cffk/c99-math-updateCharles Karney
Remove unneeded C99 compatibility functions from math.cpp and proj_math.h I'll do the clean up of the -std=c89 flags etc. as a separate pull request.
2019-09-18Delete proj_math.h. Replace includes by <math.h>; we'll see if anyoneCharles Karney
needs <limits.h>. Update scripts/reference_exported_symbols.txt and src/proj_symbol_rename.h.
2019-09-18math.cpp removed since its isnan isn't used. Keep proj_math.h (whichCharles Karney
just includes math.h and limits.h) since it's included in a score of places.
2019-09-18Get rid of dead code. The end result of this chain of commits is toCharles Karney
eliminate most of math.cpp. All that is left is the handling of isnan (and I've this because math.cpp notes that gie.c uses pj_isnan). geodesic.c now handles supplying C99 math functions internally and this can go away once C99 support is mandated.
2019-09-18Let geodesic.c use its own versions of C99 math functions if necessary.Charles Karney
2019-09-18Try removing C99 math functions from math.cpp (but leave isnan).Charles Karney

2019-09-17Fix typo in geodesic.cCharles Karney
2019-09-17Add atanh, copysign, cbrt, remainder, remquo to math.cpp.Charles Karney
The supported C99 math functions provided by math.cpp are thus hypot log1p asinh atanh copysign cbrt remainder remquo round lround Make compiler checks in CMakeLists.txt and configure.ac consistent with this set. Make geodesic.c use the math.cpp defined (instead of the internally defined) versions of hypot atanh copysign cbrt This is keyed off the presence of the PROJ_LIB macro. I had at one time https://github.com/OSGeo/PROJ/pull/1425 suggested supplying an additional macro PROJ_COMPILATION when compiling geodesic.c. However, PROJ_LIB seems to fill the bill OK. The *next* version of geodesic.c (due out in a few weeks) will also use remainder remquo All of this is only of concern for C compilers without C99 support. So this may become an historical footnote at some point.
