coordinates reference system local parameter

[aburianne]

Coordinates Reference System (CRS) are geographical meta data (ellipsoid, projection...). It is required for spatial data accurate location, surfaces, angles. It is declared by an EPSG standard code (from petroleum industry). Each statehas a local offical (and relevant) CRS. As Synpop offers solutions for different states around the world we proposes to replace hard coding of EPSG codes (i.e: 'EPSG:2154' for France Lambert 93 official) by parametric system.

• [x] declare new parameter config.crs(numerical code value)
• [x] replace value by parameter in each script
• [x] add crs to commuters.gpkg output (previously missing)
• [x] validates .gpkg outputs (Qgis open .gpkg outputs to verify declared CRS and real location)

Three files requires specific attention from reviewer

• [ ] data/spatial/iris.py : changed from constant to parametric crs value, but this is a specific file in context so maybe back to constat?
• [ ] matsim/scenario/supply/gtfs.py : doesn't support numerical EPSG code (2154), requires litteral ("EPSG:2154") instead
• [ ] matsim/scenario/supply/osm.py : tricky insert of numerical to string parameter in string chain already strongly formated

For now, we keep it fixed here.
