IGN (cx.providers.GeoportailFrance.orthos) migrated their services (wxs.ign.fr to data.geopf.fr)

[salahelfarissi]

IGN just changed their routing this month (March 2024).
https://geoservices.ign.fr/services-geoplateforme-diffusion

try:
    cx.add_basemap(
        m.ax,
        source=cx.providers.GeoportailFrance.orthos,
        attribution=True,
        crs=Maps.CRS.GOOGLE_MERCATOR,
        zoom=zoom_level,
    )
except HTTPError as e:
    logger.error("Failed to load basemap: %s", e)
    logger.warning("Continuing without basemap.")

Thanks for the report! It seems that our automatic tooling actually picked it up in f31e557. I will cut a release of xyzservices tomorrow to get it out.

[martinfleis]

I was actually wrong, we the tooling needs to be migrated.

@HaudinFlorence would you be able to look at it? You did the original implementation.

[salahelfarissi]

I can work on it if it suits you.
I already work on a web platform that generates reports and we use their services.

[martinfleis]

@salahelfarissi That would be very welcome. The code fetching the data currently lives here

xyzservices/provider_sources/_compress_providers.py

@martinfleis I can have a look if needed. @salahelfarissi Don't hesitate to tell me if you need some help

[salahelfarissi]

@HaudinFlorence @martinfleis
My first try. Please review and let me know if I need to write proper tests.
#166

[martinfleis]

@salahelfarissi it should be covered by existing test suite
