2022-03-16Transformation: no longer do vertical trasnformation when doing compound CRS ↵Even Rouault
to 2D CRS / add --3d to cs2cs Previously, when computing transformation between a compound CRS and a geographic/projected 2D CRS, the behaviour was similar to implicitly promoting the 2D CRS to 3D CRS in the pipeline computation logic, hence a geoid model could be applied. But note that when doing a geographic 3D to geographic/projected 2D CRS transformation, we *did* not do this implicit promotion and if a Helmert transformation existed between the datums, it was done only in 2D. So this is a bit inconsistent and triggered the comment in https://github.com/OSGeo/PROJ/issues/2318#issuecomment-1068924513 With this commit, we no longer do any vertical transformation when doing compound CRS to the 2D CRS, but just take the transformation of the horizontal part of the compound CRS to the 2D CRS. Said otherwise, NAD83+NAVD88 to NAD83 will no longer lead to the application of the geoid model. Unless you explicitly ask for the promotion NAD83 to 3D. Also related, in https://github.com/OSGeo/PROJ/issues/1563 that went to 6.3.0, I changed cs2cs to automatically promote to 3D the CRS as soon as one of them was compound, for the sake of being consistent with the past behaviour. But it then becomes difficult to predict PROJ behaviour depending on which level of it you consider... This commit undoes that and adds an explicit --3d switch to cs2cs, similarly to projinfo, to ask for promotion. Other bug fix found in the process, when using legacy syntax, +init=epsg:4979, (WGS 84 3D), the resulting CRS was 2D and not 3D.

2022-03-11unitconvert: round to nearest date when converting to yyyymmdd.Brendan Jurd
This resolves an issue where converting from a low-precision decimalyear to yyyymmdd gave the wrong result, due to mjd_to_yyyymmdd() truncating away the fractional time component. This commit changes the behaviour of mjd_to_yyyymmdd() to round to the nearest date, instead of truncating. Refs #1483

2021-12-20Fix and additional options for Peirce Quincuncial projections (#2978)Toby C. Wilkinson
This fixes the current forward implementation of Peirce Quincuncial proj to correctly flip/reflect out the southern hemisphere to four triangles, and rotate entire result to a square or diamond. (It there resolves the issues identified with pull request https://github.com/OSGeo/PROJ/pull/2230 , where southern hemisphere was wrongly projected over northern, and reverses the restriction to northern hemisphere introduced there). It also adds additional lateral projection of the hemispheres. - This PR adds an optional parameter `+type` which allows selection of projection. The `+type=square` and `+type=diamond` types match in principle ESRI's twin implementations of square and diamond PQ projs. The **default** if not specified is `+type=diamond`. - The previous behaviour restricted to the northern hemisphere can be reproduced using the `+type=nhemisphere`, though this is an edge case only. - An additional `+type=horizontal` and `+type=vertical` rectangular lateral versions have been added that place each hemisphere side-by-side. This is primarily to allow creation of projections such as Greiger Triptychial, which also require the additional optional params `scrollx` or `scrolly` in order to shift parts of the projection from one side of the map to the other. - Additional documentation has been added to proj description, including quoting the usual meridian used in common usage of projection, and images showing the different types.

I also removed the leading slash, since I noticed the links contained a double slash. That worked fine, but still. (cherry picked from commit 80e32d55d076fa48f753d5014cf828d85a0d1bce)
