PROJ/test/gie/4D-API_cs2cs-style.gie, branch 5.0

Take into account +towgs84=0,0,0 in pipeline to still imply geodetic->cartesian->geodetic (fixes #881)

2018-03-21T10:35:41+00:00

Introduce late expansion of +datum parameters. Fixes #872.

Merge pull request #857 from kbevers/return-error-instead-of-zeros

2018-03-12T12:58:49+00:00

Make sure that transient errors are returned correctly

Ensure cs2cs emulation gets correct ellipsoid defn (#798)

2018-02-12T19:44:00+00:00

Copy ellipsoid definition for proj=cart directly into the
proj_create call, rather than calling pj_inherit_ellipsoid_def
afterwards.

Previously, the ellipsoid definition was left out from the call.

pj_init_ctx would then pick up WGS84 from proj_def.dat, and the
init would succeed (and the possibly wrong ellipsoid definition
would later on be overwritten with the correct values by
pj_inherit_ellipsoid_def.

But if PROJ_LIB was not set or proj_def.dat was inaccessible for
other reasons, things went wrong.

Avoid invalid ellps error messages from pj_init (#794)

2018-02-12T15:45:09+00:00

Reset error type PJD_ERR_MAJOR_AXIS_NOT_GIVEN for operations
that do not need an ellipsoid.

Update a few gie tests

2018-02-10T17:31:16+00:00

Handle sign convention for vertical datum shifts

2018-02-10T13:57:50+00:00

Also make corresponding sign corrections in a number of tests,
and comment out a few tests which work correctly, but report
failure since gie is not yet ready to handle unusual axis
orders in cases with angular output coordinates.

update gie tests to agree with improved gie distance handling

2018-02-10T12:16:40+00:00

Skip gie tests that require grids

2018-02-06T20:30:42+00:00

Introduce compatibility for cs2cs-style proj-strings into the 4D API.

2018-01-31T15:25:32+00:00

Parameters such as towgs84, nadgrids and geoidgrids was previously only
handled by pj_transform(). This commit add a compatibility layer in
proj_create() by calling the pj_cs2cs_emulation_setup() function. This
function sets up a handful of predefined transformation objects on the
PJ object that is being created. Each of these transformation objects
are related to the cs2cs-style parameters we are trying to emulate in
the 4D API. That is, if the +towgs84 parameters is used we create
P->helmert with the parameters specified in +towgs84. Similarly for
+axis, +nadgrids and +geoidgrids. When these transformation objects
exists we use them in the prepare and finalize functions in pj_fwd/
pj_inv. If no cs2cs-style parametes are specified we skip those
parts of the prepare and finalizing steps.
