https://github.com/OSGeo/PROJ/pull/2536 changed the name of the
ellps=intl to "International 1924 (Hayford 1909, 1910)"
When writing a GeoTIFF file from GDAL using a SRS built from a
PROJ string, GDAL massages the datum name to
"Unknown_based_on_International_1924_Hayford_1909_1910_ellipsoid"
Before this fix, this wasn't considered as equivaleent to the non-massaged
datum name "Unknown based on International 1924 (Hayford 1909, 1910) ellipsoid"

It is no longer needed for that particular case, since there's now a concatenated
operation for it. It could in theory be useful for other cases, but removing it
doesn't break existing tests, so...

Fixes #2482
And also add proj_context_errno_string()
Revise gie 'expect failure errno XXXX' strings
|
|
from BoundCRS of projected CRS based on NTF Paris to BoundCRS of geog CRS NTF Paris. Fixes https://github.com/OSGeo/gdal/issues/3273
|
|
The big size of coordinateoperation.cpp could require significant amount
of RAM to build it with -O2 level, and cause compiler crashes in some
environments.
|
|
Add +proj=topocentric geocentric->topocentric conversion (fixes #500)
|
|
check it in the code
This is aimed at detecting running a PROJ version against a proj.db that is not
meant to work with it. This happens sometimes in complex setups mixing PROJ
versions. Hopefully this will help spotting the issue earlier.

Add option to allow export of Geographic/Projected 3D CRS in WKT1_GDAL
|
|
when attempting (non-sensical) EPSG:3855 to EPSG:4326
|
|
|
|
32N' return only the exact match
|
|
WKT1:GDAL/ESRI when GEOGCS UNIT != Degree; morph to ESRI the PRIMEM name on export
|
|
Remove proj_api.h
|
|
as CompoundCRS with a VerticalCRS being an ellipsoidal height, which is
not conformant. But needed for LAS 1.4 that only supports WKT1

fix parsing of a ProjectedCRS whose base is a Geocentric CRS
|
|
projected CRS
|
|
of a DerivedGeographicCRS (+proj=ob_tran +o_proj=lonlat +towgs84=....)
|

Gone are pj_malloc, pj_calloc, pj_dalloc and pj_dealloc. Their primary
function as API memory functions in proj_api.h is no longer there and
the other use as a workaround for old errno problems is no longer valid
either.
Replaced with malloc and free across the codebase.
|
|
|
|
|
|
Removes proj_api.h from the public API. The contents of the header file
has been moved to proj_internal.h verbatim and any references to
proj_api.h has been changed to proj_internal.h.
The documentation of proj_api.h has been removed. The only exception to
this is the API migration guides which still mention the old API.
Fixes #837

- WKT2 grammar: accept PARAMETER[name,value,id] without unit
- Recognize "Ellipsoid scaling factor" as a parameter with a scaling unit,
and defaults to Unity when not specified
- WKT2 parsing: implement the requirement of 18-010r7.html#80, that is
when a map projection parameter has no explicit unit, use metre/degree/unity
as the default unit (contrary to WKT1 parsing rules where they are deduced
from the GeogCRS angular unit and coordinate system)
