NTv1 grid shift: fix file offset for reading of shift values in ntv1_can.dat

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

of it (fixes #535)
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

2018-08-21[BREAKING] Hermert: add +convention=position_vector/coordinate_frame, ↵Even Rouault
forbids +transpose (fixes #1091) As identified in #1091, Helmert implementation in PROJ 5.0 and 5.1 is confusing. It happens that by default it used the coordinate_frame convention, contrary to the position_vector convention used traditionaly for +towgs84. The documentation of Helmert was also wrongly specifying that the default convention was position_vector. This commit: - bans the confusing +transpose parameter - removes the concept of a default convention, since in practice both are equally found, and requires +convention as soon as a rotational term parameter is present. For translation only, convention is ignored and optional, as having no effect. - fixes all the identified uses of proj=helmert in code, doc and tests This is obviously a breaking change: - users will have to adapt their pipeline expressions - in particular, init files that would use helmert must be adapted However, as designed, the break will be explicit, and not silent.
2018-08-19pj_inv(): fix inverse of +proj=longlat +geocEven Rouault
There is a regression in PROJ 5 regarding the handling of the +geoc flag, specific to the case of +proj=longlat, and the inverse transformation, which makes it a no-op: echo "12 55 0 " | src/cct +proj=pipeline +step +proj=longlat +ellps=GRS80 +geoc +inv 12.0000000000 55.0000000000 0.0000 inf With this fix, we now get: echo "12 55 0 " | src/cct +proj=pipeline +step +proj=longlat +ellps=GRS80 +geoc +inv 12.0000000000 54.8189733083 0.0000 inf The fix consists in making inv_prepare() do symetrically as fwd_finalize(), ie skip a number of transforms when left and right units are angular, and in inv_finalize() apply the (OUTPUT_UNITS==PJ_IO_UNITS_ANGULAR) processing even if INPUT_UNITS == PJ_IO_UNITS_ANGULAR

2018-06-07Add CMake configuration for test/googletest and test/unitMateusz Loskot
For CMake builds, latest googletest 1.8.0 is downloaded. Following officially recommended integration for CMake-enabled projects https://github.com/google/googletest/blob/master/googletest/README.md "Use CMake to download GoogleTest as part of the build's configure step. This is just a little more complex, but doesn't have the limitations of the other methods." Since, our copy of test/googletest - is a very minimalist copy of googletest - does not include any official CMake scripts - would require copying parts of googletest CMakeLists.txt, compilater/linker flags (e.g. -lpthreads) for reliable multi-platform builds, it is reasoanable to rely on download All pros and cons advantages are discussed in teh README.md linked above. Closes #1033

The previous commits were added way to prematurely. The code was not properly tested and it turned out to do more bad than good. This commit hopefully fixes that. And this time it is backed up by tests! DMS style coordinates should now be fully functional in gie. Finger crossed.
