Getting started with OpenSphere & using my own openstreetmap tile server

[Eric Gorr]

I was able to follow the instructions here https://opensphere.readthedocs.io/en/latest/cookbook/osm/index.html in an attempt to point OpenSphere to my tile server, however, the log file shows that things are not quite working yet. The tile server is using http and it would seem that OpenSphere wants to use https to request stuff. Is there a way to tell it to use http?

I have set this all up on Ubuntu 18.04.

For the OpenSphere settings.json file, my providers block looks like:

    "providers": {
      "basemap": {
        "type": "basemap",
        "defaults": {
          "EPSG:4326": [],
          "EPSG:3857": [ "osm" ]
        },
        "failSet": {
          "EPSG:4326": [],
          "EPSG:3857": []
        },
        "maps": {
          "streetmap": {
           //
           // just the default stuff here
           //
          },
          "worldimagery": {
           //
           // just the default stuff here
           //
          },
          "osm": {
          "title": "OpenStreetMap",
        "type": "BaseMap",
          "baseType": "XYZ",
          "provider": "OSM",
          "url": "http://192.168.254.132/hot/{z}/{x}/{y}.png",
          "minZoom": 2,
          "maxZoom": 19,
          "projection": "EPSG:3857",
          "tileSize": 256,
          "description": "OpenStreetMap rendered tiles.",
          "attributions": ["© <a href=\"https://www.openstreetmap.org/copyright\">OpenStreetMap</a> contributors"]
          }
        }
       

and the log file contains:

Where is the "fine log" located?

I can type http://192.168.254.132/hot/2/2/0.png into a browser and it will return the expected tile.

I did try joining the opensphere slack channel, but it looks like I may need an invite or something...

Any insights into what might be going on and how I can get OpenSphere to point to my internal tile server would be appreciated.

Did you check the browser for CORS issues? The Cesium/3D views require proper CORS to work:

"osm": {
  "title": "OpenStreetMap",
  "type": "BaseMap",
  "baseType": "XYZ",
  "provider": "OSM",

  "crossOrigin": "anonymous",
  "url": "http://192.168.254.132/hot/{z}/{x}/{y}.png",

  "minZoom": 2,
  "maxZoom": 19,
  "projection": "EPSG:3857",
  "tileSize": 256,
  "description": "OpenStreetMap rendered tiles.",
  "attributions": ["© <a href=\"https://www.openstreetmap.org/copyright\">OpenStreetMap</a> contributors"]
}

Also, the fine log is accessed by Support > View Log > Options > change the root logger to "Fine"
