2019-12-02Database: register the BWTA2017.gsb grid (DHDN->ETRS89 for Baden-Wurtemberg)Even Rouault
Relates to https://github.com/OSGeo/proj-datumgrid/pull/65 , https://github.com/OSGeo/proj-datumgrid/issues/22 As EPSG has no entry for it, we create a grid_transformation, as well as a dedicated area of use based on the extent of the grid, under the PROJ authority. With the hope to be able to remove it once EPSG has an entry...
2019-12-01Enhance PROJ resource file lookup on Windows for bin\..\share\proj (#1755)Joaquim
This PR is Windows only. It adds the directory ``.....\bin\..\share\proj``, where ``....\bin`` is the directory hosting ``proj.dll``, to the list of places where ``proj.db`` is searched. In addition to what happens at build time, this PR ads also the ability to do that at run-time. This means that a structure like ....\bin\proj.exe, proj.dll, ... ....\share\proj\proj.db, ... will still find proj.db without needing to set the PROJ_LIB environment variable

2019-11-25PROJStringFormatter::toString(): optimize hgridshift, vgridshift, hgridshift ↵Even Rouault
inv constructs Given an initial pipeline with +step +proj=hgridshift +grids=foo +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo Transform it as +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +omit_inv +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo +omit_fwd +step +proj=pop +v_1 +v_2 So as to avoid doing a double application of the hgridshift.
2019-11-25Pipeline: support +omit_fwd and +omit_inv keywordsEven Rouault
Inspired from syntax of https://github.com/OSGeo/PROJ/pull/453/files but 'rebased' on top of previous commit that cleans up the pipeline implementation Different situations: - +omit_fwd: the step when followed in the forward path will be omitted the step when followed in the reverse path will be executed - +omit_fwd +inv: the step when followed in the forward path will be omitted the step when followed in the reverse path will be executed (with the inv method) - +omit_inv: the step when followed in the forward path will be executed the step when followed in the reverse path will be omitted - +omit_inv +inv: the step when followed in the forward path will be executed (with the inv method) the step when followed in the reverse path will be omitted This will be used in the next commit to optimize constructs like +step +proj=hgridshift +grids=foo +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo Such steps are used for CRS to CRS transformations where applying the vertical grid requires to do a transformation to an interpolating CRS. One can notice that in the last step will just restore the horizontal coordinates before the first step, so doing an inverse hgridshift is overkill. So that could be optimized as: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +omit_inv +step +proj=vgridshift +grids=bar +step +inv +proj=hgridshift +grids=foo +omit_fwd +step +proj=pop +v_1 +v_2 In the forward path, this will be equivalent to: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +step +proj=vgridshift +grids=bar +step +prop=pop +v_1 +v_2 And similarly in the reverse path, this will be quivalent to: +step +proj=push +v_1 +v_2 +step +proj=hgridshift +grids=foo +step +inv +proj=vgridshift +grids=bar +step +proj=pop +v_1 +v_2
2019-11-25normalizeForVisualization() and other methods applying on a ProjectedCRS: do ↵Even Rouault
not mess the derivingConversion object of the original object (fixes #1736) normalizeForVisualization(), promoteTo3D(), demoteTo2D(), alterGeodeticCRS(), alterCSLinearUnit() and alterParametersLinearUnit() all used the object returned by derivingConversionRef() to create a new ProjectedCRS. While doing so, this caused the derivingConversion of the original object to have its targetCRS set to the object returned by normalizeForVisualization() and similar. If that object died, then the weak pointer would be reset, and the original ProjectedCRS() has now its derivingConversionRef()->targetCRS() nullptr So bottom line is use derivingConversion() for anything that is not pure reading !!! This is confirmed to be the fix for the QGIS scenario in https://github.com/qgis/QGIS/issues/30569#issuecomment-540060919 In QGIS use case, the issue arised when using a projected CRS with a non-GIS friendly axis (that is where normalizeForVisualization() created a new projectedCRS)

2019-11-09Doc: document oddity related to identification of CRS from ESRI WKTEven Rouault
Or more generally formulations that don't have an explicit axis order. Refs https://github.com/pyproj4/pyproj/issues/475 projinfo 'GEOGCS["GCS_WGS_1984",DATUM["D_WGS_1984",SPHEROID["WGS_1984",6378137.0,298.257223563]],PRIMEM["Greenwich",0.0],UNIT["Degree",0.0174532925199433]]' returns EPSG:4326 with 100% confidence. But its axis order is not the same as EPSG:4326. I've pondered about this, like decreasing the confidence of the match, but this would have downstream effects on GDAL (shapefiles with the above content in a .prj would no longer be identified as EPSG:4326). So for now, document that oddity.
