Route planner service

Implement route planner service from IGN for isodist and isochron : https://geoservices.ign.fr/services-web-experts-calcul

@sylvaine31 has already developed a function for isochrone. She contacted me to add it to happign. This will be done in the next version.

Hi @sylvaine31,

La fonction get_iso est implémentée dans la version en développement d'happign (install_github("paul-carteron/happign")) ! J'ai également implémenté deux fonction wrapper get_isodistance et get_isochrone. Pour le moment le paramètre constraint n'ai pas utilisable.

Si vous avez le temps de les tester avec vos cas d'études ce serait super !

PS : Bien vu pour le vectorisation de la fonction permettant de prendre plusieurs points en entrée !

Hi Paul, I saw you removed the get_iso function. Perhaps you had problem with the function ? The function I create did not function anymore since the geoplateforme migration. I fixed it using the bdtopo-pgr resource instead of bdtopo-iso which is broken on the new plateform. Hope that help !

Hi Sylvaine, Exactly ! The function doesn't work anymore with the Geoplateforme, if you have a working one, i'll be glad to add it in the next release.

I think just change the resourcedefault argument to bdtopo-pgr should do the trick

and of course change the api adress to "https://data.geopf.fr/navigation/isochrone?"

It's now implemented in development version. I also add valhalla as new source. Thanks !
