Supported data types
The following data types are supported in Sites:
- Feature layer
- Map layer
- Image layer
- CSV files
- Web maps
Sites does not currently support raster layers within map services.
Improve data quality
To optimize the usability of your data in Sites, it is important that your data be complete with an accessible title, description, attribute aliases, license, and tags.
- Title—For individual layers, change the title in your Enterprise portal to be clear and informative. For layers within map or feature services, change the title locally, and publish the service with clean titles. Sites will remove any underscores in your title.
- Description—Change the description in your Enterprise portal. Layers within map or feature services will take the description of the entire service. If you do not enter a description, Sites will automatically provide Description not provided
- Field aliases—Change complex GIS data field names to a more user-friendly description of the content of the field. Dataset downloads will supply the field name, but not the field alias.
- Tags—Tags help users discover your datasets through searches. For individual layers, add tags in your Enterprise portal. All layers within map and feature services will have the same tags as set for the entire service in your Enterprise portal.
- Thumbnails—Enterprise portal item thumbnails will appear beside the dataset in the search results. All layers within map and feature services will have the same thumbnail.
- Structured Metadata—Add official metadata files to your Enterprise portal item and users can access it via Sites.
Sites downloads will change the data schema so that all values will be within the signed range of integer values that can be stored in 32 bits. This means that field lengths, field precision, and scale may be altered in the download. The data itself will not change.
Only the following HTML tags will be respected in the Description and License fields on Sites. Text in other tags will appear in-line: 'h3', 'h4', 'h5', 'h6', 'img', 'blockquote', 'p', 'a', 'ul', 'ol', 'nl', 'li', 'b', 'i', 'strong', 'em', 'strike', 'code', 'hr', 'br', 'div', 'table', 'thead', 'caption', 'tbody', 'tr', 'th', 'td', 'pre'.
Services must be registered to your Enterprise portal to be added to a site. When working with map and feature services, you can register services containing multiple layers, or register the individual layers themselves. Layers from federated services will be in your Enterprise portal automatically.
Register services with multiple layers
This is a quicker way of getting your data live, but it gives you less control over search results and an item's metadata. All layers within the service will have the same description and the same tags, and all layers will appear in search results when a tag or the service name is called.
Register individual layers
Individual layers provide greater control over the item's metadata—you can edit individual titles and descriptions within your Enterprise portal. Each layer will have different tags as set in your Enterprise portal, which will provide better search results for the end user.
To learn more about registering services and service configuration, see Server configuration details.
Add additional download files
All (vector) datasets are automatically available for download as CSV files, KML files, and shapefiles and accessible in the GeoJSON and GeoService APIs. You can add additional download files or related documents by adding custom distributions to the dataset's structured metadata. This is a good way to support CAD file download formats or file geodatabases for nonhosted feature services. Additional download files that you add in the metadata will appear as options in the download section of the dataset page on Sites.
To add additional download files, follow these steps:
- On the item page in the home application, click Metadata.
Note:If you do not see a metadata button, you must have an administrator enable metadata for your portal.
- On the metadata form, click Distribution.
- On the Online Resource page that appears, click the plus sign.
- Enter a URL to your download file or external related link.
- Enter a name for the file. This name will appear on ArcGIS Sites.
- Change the Function parameter to Download.
You can add as many additional download files as you want by repeating steps 3 through 6.
Entering additional distributions in the metadata will expose the entire metadata to the user in Sites. Datasets are encouraged to have complete, structured metadata.
