Motivation

Hello, I would like to add OpenTopoMap as a base layer I have tried several json variants but nothing. Perhaps it would also be useful to better document how to insert OpenTopoMap or other base layers. Regards

Suggested solution

It would be useful to be able to add more alternatives

Hi @BaBoWaGa please report your G3W-SUITE version and post here an example of json you tried.

Hi @wlorenzetti sorry for the delay monster, G3W-SUITE Version 3.8.
Among the various tests ....

{
"type": "tilelayer",
"url": "https://tile.opentopomap.org/{z}/{x}/{y}.png",
"crs": {
"epsg": 3857,
"proj4": "+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs",
"geographic": false,
"axisinverted": false
},

Hi @BaBoWaGa on v3.8.x this works for me:

{
   "crs":{
      "epsg":3857,
      "proj4":"+proj=merc +a=6378137 +b=6378137 +lat_ts=0.0 +lon_0=0.0 +x_0=0.0 +y_0=0 +k=1.0 +units=m +nadgrids=@null +wktext +no_defs",
      "geographic":False,
      "axisinverted":False
   },
   "url":"https://a.tile.opentopomap.org/{z}/{x}/{y}.png",
   "servertype":"TMS",
   "attributions":""
}

Thank you very much, unfortunately I lack this expertise. Anyway, I had tried a very similar one and only got the servertype wrong.

If it is not too much to ask, how could I configure the json for
Name ESRI Satellite
URL https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}
Source type=xyz&zmin=0&zmax=20&url=https://server.arcgisonline.com/ArcGIS/rest/services/World_Imagery/MapServer/tile/{z}/{y}/{x}
Data source wms

What size and format should the base map representation icon have?

Staying on the subject, given that many base maps have a paid key for display (Bing and Google Maps first), wouldn't it be possible in the future to have base maps that are 'activated' based on the user/user group?
Same for geocoding providers

Thanks
