2016-02-15geodesic.c: move declarations to beginings of functions.Charles Karney
2016-02-15Upgrade geodesic library from GeographicLib 1.46.Charles Karney
* upgrade geodesic.[ch3] * add test suite geodtest.c and invoke via cmake's add_test * increment version to 4.9.3 and library version to 11.0.0
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
