Elevation can help with 3D visualizations by creating relief in your 3D scene. Elevation surfaces define height values across the extent of a map or scene. Other layers are usually draped on top of the elevation. In most cases, data for an elevation layer comes from an elevation service. Currently, tiled elevation layers are supported in the LERC format.
The following types of source URLs can be used to add an elevation layer and create relief in your ArcGIS Map:
- Item page URL
- Elevation service URL
Elevation tiles can also access data from LERC encoded tile packages stored locally.
A tile package is a single .tpk (or .tpkx) file containing tiles, and you can share the file as you would with any file. Compared with .tpk files, .tpkx files provide better performance on network shares and cloud store directories. The spatial reference of the elevation should match with the basemap and image tile layers. See Spatial references for more information about coordinate systems.
When you have multiple elevation sources, the last item added to the collection takes precedence and is displayed topmost in the Map Creator UI.
The Terrain 3D from ArcGIS Online and its spatial reference is Web Mercator (Auxiliary Sphere).
To use the default elevation source, click the Elevation tab, and select Terrain 3D.
To use custom elevation sources:
Click the Elevation tab, and select the Default Elevation or select Custom Elevation to set a custom elevation source in the panel.
- Click + Add New at the bottom right in the Elevation panel to open the pop-up window.
- Enter the online service URL for the elevation service or a local file package path in the Source field.
- Add the name of the source in the Name field.
- Click Add.
- Find the newly added elevation source in the Elevation panel.
- To use a
.tpkxfile package as an elevation source, use the absolute file path for the Source.
- To change the elevation source order, click ⋮ and select Move up or Move down.
- The elevation source at the top of the list has the highest priority.
- To change an additional elevation source name, click
