2018-05-30Fix warnings found by clang with new warning flags to be added in later commitEven Rouault
Fixes consist in: - no use of comma operator for multi statement purpose - avoid confusing comma in for loops first and third clauses - avoid implicit long to int casts by storing to long, or explicit bound checking before cast

2018-03-17Fix comments in geodesic.c. Better invocation of AX_CHECK_COMPILE_FLAG,Charles Karney
but I doubt this will fix the build failures on the CI machines.
2018-03-17Patch 1.49.3 for geodesic package.Charles Karney
Set flags for Intel compiler to prevent incorrect optimization of arithmetic expressions #826. Guard against nans in sincosdx #834. Issue #831 is not addressed here (need more information...).

2018-02-23Add tests to improve the code coverage.Charles Karney
Now all of geodesic.c is covered except for 3 lines (and 2 of these are intentionally dead code). This corresponds to tag v1.49.2-c in the GeographicLib code base. While testing polygons which encircle the globe multiple times, I uncovered a problem where the range of the area was not reduced to the allowed range (either [0, area0) or (-area0/2, area0/2]) correctly. Since the documentation explicity restricted the calculation of polygon areas to simple polygons, we'll defer fixing this for now. (However the intention was always to handle the area "algebraically" so that, for example, a "bowtie" has zero area. So I will plan on fixing this for 1.50.) Update copyright dates + NEWS.
2018-02-22Fix issue #812Charles Karney
Implement Polygon AddEdge fix in C library (will be version 1.49.2 of C library for proj 5.0.0). Still to do: add tests to expand code coverage. This will only affect geodtest.c which is not part of the compiled library.
2017-12-18Fix issue #715. Merge 1.49.1 of geodesic library (tagged as v1.49.1-cCharles Karney
in GeographicLib). Details: Workaround bugs in handling of -0.0 in fmod and sin in Visual Studio 10, 11, and 12. Relax unrealistically strict delta for GeodSolve59 in geodtest.
2017-08-29Release candidate for geodesic library version 1.49.Charles Karney
Only substantial changes are (1) testing the HAVE_C99_MATH flag and acting accordingly and (2) adding a couple of tests.

2017-04-09Merge is geodesic routines from GeographicLib 1.48. Changes:Charles Karney
- http://geographiclib.sf.net -> http://geographiclib.sourceforge.io - backport fixes for warnings messages from some compilers - change default range for longitude and azimuth to (-180d, 180d] (instead of [-180d, 180d))

Improve accuracy of area calculation (fixing a flaw introduced in version 1.46). Changed files geodesic.[ch3], geodtest.c, geod.1.

2015-08-16Drop in the latest geodesic library from GeographicLib (version 1.44).Charles Karney
http://geographiclib.sourceforge.net/1.44/C/index.html The changes are: - Improve accuracy of calculations by evaluating trigonometric functions more carefully and replacing the series for the reduced length with one with a smaller truncation error. - The allowed ranges for longitudes and azimuths is now unlimited; it used to be [-540d, 540d). - Enforce the restriction of latitude to [-90d, 90d] by returning NaNs if the latitude is outside this range. - The inverse calculation sets s12 to zero for coincident points at pole (instead of returning a tiny quantity). This commit also includes a work-around for an inaccurate value for pi/180 in dmstor.c (see the definitions of DEG_IN and DEG_OUT in geod_interface.c).

< 4.6 case
2015-05-20Update to version 1.43 of the geodesic routines. This fixes twoCharles Karney
relatively obscure problems. (1) The business of returning an unrolled longitude with the solution to the direct problem was broken for west-going geodesics. (2) For flattening > 1/100, a slight inaccurate result was returned for a12 in the direct calculation. git-svn-id: http://svn.osgeo.org/metacrs/proj/trunk@2656 4e78687f-474d-0410-85f9-8d5e500ac6b2
