https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/elevation-profile-from-multiple-layers/m-p/1514884#M85191 <P>We have multiple (generally two) layers set for the Elevation widget as ground layer collection. There is only one ground profile displayed.&nbsp;We already figured out that it is possible to mix multiple layers, if one of the layers does not return any elevation value (e.g. outside of a country borders) the other one will be used for that part of the profile line.</P><P>Yet the documentation does not state how the profile is calculated if both layers <STRONG>do</STRONG> provide correct elevation results. Is it based on the order of the layers in the ground collection? So if the first layer has a value, the second layer won't be queried at all? We'd need an exact answer for this kind of situation.</P><P>Thanks!</P> Mon, 05 Aug 2024 11:52:50 GMT ImreZuber 2024-08-05T11:52:50Z https://community.esri.com/t5/arcgis-javascript-maps-sdk-questions/elevation-profile-from-multiple-layers/m-p/1514884#M85191 <P>We have multiple (generally two) layers set for the Elevation widget as ground layer collection.
