Hi,

 

I have created a web map and the spatial reference in the web map data when I request the specific item is (presumably based on the base layer spatial reference?):

    "spatialReference": {
        "wkid": 102100,
        "latestWkid": 3857
    }

 

but the extent in the web map content item is:

        "extent": [[105.533276992,
        -43.6430919145],
        [159.105442464,
        -9.23004701800001]]

What is the spatial reference of the extent? Is it EPSG:4326 and if so is this always the case for web maps? I could not find a definitive reference for this.

 

Cheers,
Chris Mugdan
