In ArcGIS Pro, you can author and share web tile layers that are stored as items in your active portal. These web layers are useful when you need to expose a map or layer on the web for the visualization of relatively static data. The privilege to publish hosted tile layers is required to share a web tile layer.
When sharing a tile layer to ArcGIS Enterprise, the data option Copy all data must first be selected to be able to select Tile as the Layer Type.
Share a web tile layer using the default configuration
- To share a web tile layer with the default ArcGIS Online/Bing Maps/Google Maps tiling scheme, do one of the following:
- Share the map and all its layers as a web layer. On the Share tab, in the Share As group, click Publish Web Layer .
- Share selected layers from the map as a web layer. Select the layers in the Contents pane. Right-click the selected layers, point to the Sharing menu, and click Share As Web Layer .
The Share As Web Layer pane appears.
- Provide a name for the web layer.
- Complete the Summary and Tags fields.
- If you are sharing to ArcGIS Enterprise, select Copy all data.
- For Layer Type, click Tile.
- Use the Folder menu to specify where the web layer will be stored in your portal content. The web layer is stored in the root of your content by default. Optionally click the Browse button to create a folder or choose an existing one. You can also type the name of the desired folder in the text box.
- Specify how the web layer will be shared:
- My Organization—This option allows your content to be shared with all authenticated users in the organization.
- Everyone—This option makes your content public. Anyone can access and see it.
- Groups—You can share your content with groups you belong to and their members.
- Optionally click the Content tab to view the new web layer that will be created and all its components.
- Click Analyze to check for any errors or issues. You must resolve all errors. If any issues are discovered, they appear on the Messages tab. Right-click each message to get more information, read the help for the error or warning, and access suggested fixes.
- Once validated, click Publish to share your web layer using the default configuration.
- Once the web layer has been successfully published, you can do the following:
- Click the Jobs button to view the cache generation status of the published web tile layer in the Job Status pane.
- Click the Manage the web layer link to view the cache status or manage tiles for the web tile layer through your portal.
Configure a web tile layer
You can configure your web tile layer prior to publishing to specify a tiling scheme, the level of detail to cache, and if the cache is built automatically or manually on the server or built locally.
Antialiasing options, set for the application on the Display tab on the Options dialog box, are applied when you publish a web tile layer. The default antialiasing mode is Best.
- Click the Configuration tab. If your active portal is ArcGIS Enterprise, click Configure Web Layer Properties to access the configurable properties.
- Choose a Tiling Scheme that defines the 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 256 by 256 pixels. Scale levels for caching range from zero to 23. 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.
WGS 1984 Geographic Coordinate System, Version 2
A tiling scheme based on the WGS 1984 Geographic Coordinate System. The coordinate system of the web layer is reprojected on the fly to WGS 1984 Geographic Coordinate System. The default tile width and height is 256 by 256 pixels. Scale levels for caching range from zero to 22. When you initialize a new cache, ArcGIS Pro examines the layers in your map 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 tile 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, with the exception of antialiasing. Antialiasing options set for the application are used.
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 scene.
Web tile layers that are published when a web map is shared will automatically use the tiling scheme associated with the web map's basemap.
In ArcGIS Pro 1.1 and 1.2, a previous version of the WGS 1984 Geographic Coordinate System tiling scheme was available. An improved version of this tiling scheme, with higher registration accuracy at higher resolutions (detailed scales), has replaced the old tiling scheme, and is called WGS 1984 Geographic Coordinate System, Version 2.
Cached web layers that use the old tiling scheme cannot be displayed with tile layers that use the new tiling scheme in certain clients due to differences in the tiling schemes. If you need to continue using the old tiling scheme, choose Existing cached map/image service for your Tiling Scheme and browse to a service that uses the old tiling scheme.
- Use the sliders to set the Levels of Detail property. ArcGIS Pro examines the dependencies in your map or layer and attempts to suggest a minimum and maximum range of scales for caching. Depending on your map or layer, you may want to forego caching some of the extremely large or small scales in your tiling scheme.
- Choose when and where to build the cache. The default setting is to build the cache automatically on the server. Use the reported Estimated cache size to help you make this choice.
Cache automatically on the server
If the cache is small, it is easiest to build the whole cache automatically. This is the default setting.
Cache manually on the server
If the cache is large, it is wise to build the cache manually in phases, caching the largest scales at selected areas of interest that are most likely to be visited. You can manually build the cache from the ArcGIS Online website or ArcGIS Enterprise website.
If you want to minimize the number of credits consumed when sharing to ArcGIS Online or if you want to reduce the number of resources used when sharing to ArcGIS Enterprise, use this option. When using this option, the cache is temporarily saved as a tile package that is then uploaded and unpackaged automatically.
- If you chose to Cache locally, you can modify the Temp cache location if the default staging location does not have enough disk space for the temporary tile package.
- Optionally, select the Allow clients to export cache tiles check box to allow clients to download map tiles for offline use.
- Specify a value to limit how many tiles can be downloaded in a single request using the Limit export to parameter.
