Before you start

  • I searched the existing issues and the roadmap and did not find a duplicate request.

What problem does this solve?

esri_datum_corpus.tsv and wkt2_corpus.tsv guard the CRS readers against regressions, as #807/#850 and #510 showed. Italy is covered by 3003, 3004, 3064, 6707, 23032 and 25832 in the ESRI corpus, and only 25832 in the WKT2 one. Italian data is spread over many more systems: the second UTM zone (33), RDN2008 in both axis orders, the national "Italy zone" and "Zone 12" grids, the geographic Monte Mario, IGM95 and RDN2008, and Monte Mario with the Rome prime meridian.

I tested 25 of them with RustGIS 0.4.0 (Windows portable, rustgis-cli), each with one point in an Italian city of its zone, read three ways:

  1. a GeoPackage with the EPSG code;
  2. a Shapefile whose .prj is the ESRI WKT1 that GDAL 3.13 writes (MorphToESRI);
  3. a Shapefile whose .prj is WKT2 2019 without ID or usage (pyproj 3.7).

24 of 25 match the EPSG transformation to the centimetre by all three paths. That includes RDN2008 N-E and E-N (6707/7791, 6708/7792, 6709/7793), Italy zone (6875/7794), Zone 12 (6876/7795), ED50 33N/34N, IGM95 33N and the geographic 4265, 4670 and 6706. Each expected value matches a named EPSG transformation in PROJ 9.8 within 1 cm: Monte Mario to WGS 84 (4), ED50 to WGS 84 (1), IGM95 to WGS 84 (1), RDN2008 to WGS 84 (1), ETRS89 to WGS 84 (1).

One gap: Monte Mario (Rome), EPSG:4806. By its EPSG code it is right: lon/lat measured from Rome, then Monte Mario to WGS 84 (4), 0.00 m. From its ESRI .prj (GEOGCS["GCS_Monte_Mario_Rome",DATUM["Monte_Mario_(Rome)",...],PRIMEM["Rome",12.4523333333333],...]) and from its WKT2, RustGIS applies the prime meridian but no datum shift. It shows the notice "the datum Monte_Mario_(Rome) has no conversion to WGS 84 in the file", and the point lands 73.1 m off in Rome. It is the same case as #807 with the Rome meridian: the datum is Monte Mario, so it could get the same Helmert.

(Note for anyone checking with pyproj: Transformer.from_crs("EPSG:4806", "EPSG:4326") without an area of interest picks a ballpark operation at that point, so it is not a valid reference. Going through EPSG:4265 with the exact meridian change is.)

Proposed solution

  1. Add the rows below to the two corpora. In wkt2_corpus.tsv, longitude and latitude are WGS 84 with the bundled Helmert shift, as for OSGB36, Amersfoort and GGRS87, because RustGIS now applies the shift to Monte Mario and ED50 read from WKT2; for IGM95, RDN2008 and ETRS89 the two are the same. The assert_eq!(rows.len(), 60) would become 84.
  2. Recognise Monte_Mario_(Rome) / Monte Mario (Rome) with PRIMEM["Rome",12.4523333333333] as Monte Mario. Until then, the 4806 ESRI and WKT2 rows fail, which is why I am not opening a pull request with them straight away.

I'm happy to open the pull request with the rows, or a draft one with the 4806 rows marked as expected failures, whichever suits you.

Estimated scope

Test data only for point 1. Point 2 is an alias for MONTE_MARIO_(ROME) in national_datum (crates/data/src/raster/wkt.rs, which today matches MONTE_MARIO only), keeping the Rome prime meridian that the reader already applies.

Alternatives considered

Keeping the cases outside the repository, in a test bench of our own. That only finds a regression after a release.

    I think I found the cause. national_datum in crates/data/src/raster/wkt.rs only matches the name MONTE_MARIO. Monte_Mario_(Rome) normalises to MONTE_MARIO_ROME, matches nothing, and gets the "no conversion to WGS 84" note. The prime meridian is still applied separately (+pm= in earth), which fits your 73 m offset. WKT2 is converted to WKT1 before this lookup, so one "MONTE_MARIO_ROME" => 4265 arm should fix both paths, and the existing ellipsoid check still applies. The corpora are thin for Italy (ESRI has 3003 and 3004 but no 4806; WKT2 has only 25832), so I'd add your 25 rows plus a 4806 regression. Do you want to send that PR?
