Map thumbnail when using HTTP POST

[bertt]

Hi, I'm creating a map by using HTTP POST to /api/v2/maps. payload sample:

{
  "title": "testmap",
  "abstract": "testmap",
  "data": {
    "map": {
      "projection": "EPSG:3857",
      "units": "m",
      "zoom": 5,
      "center": {
        "x": 517164.3275252839,
        "y": 6842056.397470128,
        "crs": "EPSG:3857"
      },
      "maxExtent": [
        462271.7796363245,
        6796328.352314704,
        572680.2784587856,
        6887664.30256273
      ],

I'm expecting that the thumbnail shows only the maxExtent area, but it shows the whole world:

Q: Is there a way to get a correct thumbnail when using HTTP POST?

[giohappy]

maxExtent has no effect on the thumbnail extent.
The extent of the thumbnail is obtained by the extent of the maplayers (from GeoNode datasets) contained in the map.

ok clear, if I try a map with only 1 dataset (a wms layer behind the scenes), it still shows the whole world as thumbnail.

In the metadata of the dataset it shows the correct bounding box:

Hi @bertt the thumbnail is not automatically re-calculated every time you save the map, but it needs to be re-set manually.
To do it, open the map properties and on the top click on the "set map as an image"

In this way, the image on the top become an interactive map and you can re-select the thumbnail as you prefer
