Web elevation layer

You can author and share web elevation layers to ArcGIS Enterprise by sharing a web scene in ArcGIS Pro. Each elevation source in your scene's ground surface will be published as a separate web elevation layer. The privilege to publish server-based layers is required to share a web elevation layer.

Note:

The elevation surface properties Vertical exaggeration, Surface color, and Shade surface relative to the scene's light position are not maintained through the sharing process.

Share a web elevation layer

At this release, web elevation layers can only be shared to ArcGIS Enterprise within a web scene. For more information on sharing a web scene, see Share a web scene.

To share a web elevation layer to ArcGIS Online, a tile package is created and shared to ArcGIS Online. For more information, see Tile package.

Configure a web elevation layer

If your scene has a basemap layer, existing web elevation layers, or web tile layers, all new elevation layers will automatically use the tiling scheme defined by the existing service. For more information on tiling scheme requirements, see Basemap and elevation layers. The following workflow is specific to sharing a web elevation layer as part of a web scene and is not applicable to sharing a tile package.

  1. Click Configure Web Layer Properties Configure Web Layer Properties.
  2. Click the Configuration tab.
  3. Choose a Tiling Scheme that defines the desired scale levels, tile dimensions, and tile origin for the cache. These properties define where tile boundaries will exist and are important to match when overlaying caches. Tiling scheme options include the following:
    ArcGIS Online/Bing Maps/Google Maps

    This is the default tiling scheme. The coordinate system of the web layer is reprojected on the fly to WGS 1984 Web Mercator (Auxiliary Sphere) to ensure your web tile layer overlays with these online services. The default tile width and height is 256x256 pixels. Scale levels for caching range from 0–19. When you initialize a new cache, ArcGIS Pro examines the layers in your GIS resource and selects a default tile image format for you. If your GIS resource contains only vector layers, the default is PNG. If at least one raster layer is detected, the default is MIXED.

    Existing cached map/image service

    Use an existing hosted or ArcGIS Server web tile layer or an ArcGIS Server image service as the tiling scheme of your web elevation layer. When you choose this option, the tiling scheme XML file associated with the existing service is downloaded to C:\Users\USERPROFILE\My Documents\ArcGIS\TilingSchemes\Downloaded. ArcGIS Pro will honor the parameters specified in the existing service, with the exception of antialiasing. Antialiasing options set for the application are used.

    Tiling scheme file

    Import a custom tiling scheme XML file you have created that contains your preferred scales and settings. Use the Generate Map Server Cache Tiling Scheme geoprocessing tool to create a custom tiling scheme XML file. Additional tiling scheme files can also be imported from C:\Program Files\ArcGIS\Pro\Resources\TilingSchemes. The tile image format will default to PNG if the tile image format is not defined in the tiling scheme file. ArcGIS Pro will honor the parameters specified in the tiling scheme file.

    Auto-suggest

    A tiling scheme is suggested based on the coordinate system of your scene. The levels of detail defined in this tiling scheme are valid for a global extent, so datasets in the same coordinate system that are cached using this tiling scheme can be displayed together in the future. Although the tiling scheme is valid for a global extent, only the extent defined in the map properties will be cached.

    This option is only available when sharing a local scene.

    If you have a basemap, existing web elevation layer, or web tile layer in your scene, you cannot change the tiling scheme.

  4. Choose whether to Cache automatically on the server or Cache manually on the server.
  5. Optionally change the LERC Compression.

    The web elevation layer will be cached using LERC (Limited Error Raster Compression). Specify a tolerance value that represents the maximum allowable error per pixel in the units of the data. For example, if the dataset is in meters and you want to ensure accuracy within 10 cm, enter 0.1.

Considerations when sharing to older portals

Web elevation layers cannot be shared to Portal for ArcGIS 10.3.1 or later.
