custom "proj4" project map

[duretf]

Hello,

From France (Meteo-France), a use case for map projection is something like proj4 (i.e "EPSG:27572", "+proj=lcc +lat_1=46.8 +lat_0=46.8 +lon_0=0 +k_0=0.99987742 +x_0=600000 +y_0=2200000 +ellps=clrk80ign +pm=paris +units=m +no_defs +type=crs").

But only a short list is given such as "lambert", is it possible to set map projection with this string proj4 definition ?

In production, Magics is limited to these short list, and it is not enough. We have to introduce other libraries and rendering can be not consistent.

Do you have a solution for EPSG and custom proj4 defs in map projection configuration ?

Best regards F.D
