2018-10-08NTv1 grid shift: fix file offset for reading of shift values in ntv1_can.datEven Rouault
When investigating the format of NTv1 and comparing PROJ code with the actual header of ntv1_can.dat, I discovered that the longitude & latitude shift values started at offset 192, whereas PROJ assumed that the header was 176 bytes only. This caused PROJ to use the wrong offsets values (shift of one grid sample by longitude). So the effect was moderately visible, especially on the latitude, but when comparing with NTv2, one can see that the longitude value after the fix seems to closer to NTv2. old: echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022624 -100.50040292 0.00000000 inf new: echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022403 -100.50041841 0.00000000 inf echo "60.5 -100.5 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=$HOME/proj/proj-datumgrid/north-america/ntv2_0.gsb +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 60.50022348 -100.50041978 0.00000000 inf old: $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096789 -70.89746834 0.00000000 inf new: $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=ntv1_can.dat +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096858 -70.89749190 0.00000000 inf $ echo "80.1 -70.9 0" | PROJ_LIB=/usr/share/proj src/cct -d 8 +proj=pipeline +step +proj=axisswap +order=2,1 +step +proj=unitconvert +xy_in=deg +xy_out=rad +step +proj=hgridshift +grids=$HOME/proj/proj-datumgrid/north-america/ntv2_0.gsb +step +proj=unitconvert +xy_in=rad +xy_out=deg +step +proj=axisswap +order=2,1 80.10096782 -70.89749276 0.00000000 inf

Before that, approximately half of the descriptions had a period at the end, e.g. 'Cyl.' or 'Sph.' and the other half did not have those periods. This commit drops all the dots in PROJ_HEAD descriptions.

2018-10-01Add geographic offset transformation method.Even Rouault
The Geographic offsets transformation adds an offset to the geographic longitude, latitude coordinates, and an offset to the ellipsoidal height. This method is normally only used when low accuracy is tolerated. It is documented as coordinate operation method code 9619 (for geographic 2D) and 9660 (for geographic 3D) in the EPSG dataset. It can also be used to implement the method Geographic2D with Height Offsets (code 9618) by noting that the input vertical component is a gravity-related height and the output vertical component is the ellispoid height (dh being the geoid undulation). It can also be used to implement the method Vertical offset (code 9616) It is used for example to transform: - from the old Greek geographic 2D CRS to the newer GGRS87 CRS - from Tokyo + JSLD69 height to WGS 84 - from Baltic 1977 height to Black Sea height It is also useful to document the implicit zero-offset transformation we do in pipelines such as +proj=pipeline +step +inv +proj=longlat +ellps=A +step +proj=longlat +ellps=B that can be explicited as +proj=pipeline +step +inv +proj=longlat +ellps=A +step +proj=geogoffset [+dlon=0 +dlat=0 +dh=0] +step +proj=longlat +ellps=B

There was an issue since transformation.rst which uses this citation is alphabetically after references.rst. The documented workaround in https://github.com/mcmtroffaes/sphinxcontrib-bibtex/issues/8 is to rename references.rst as zrefereces.rst, so it is alphabetically last.

2018-09-27cs2cs_emulation_setup: fix issue with non C-localeEven Rouault
in +towgs84 case, we use sprintf() with floating-point formatter to output the ellipsoid parameters. For a locale with decimal separtor != dot, the resulting string will not be parsed correctly by proj_atof(), leading to wrong numeric result. The fix is similar to the one done in pj_latlong_from_proj() Note for later: if using C++, we could use a locale-independent formatting solution to avoid such issue.

2018-09-18Only allow usage of proj_api.h if explicit consent was givenKristian Evers
We want to flag that proj_api_h is now deprecated. With this commit it is now mandatory to #define ACCEPT_USE_OF_DEPRECATED_PROJ_API_H before proj_api.h can be included. proj_api.h is used internally a bunch of places. Therefore ACCEPT_USE_OF_DEPRECATED_PROJ_API_H has been defined in projects.h and a few other necessary files to ensure that PROJ compiles. Closes #836
