Manage hosted feature layers

You can alter certain settings on a hosted feature (or table) layer, while others are set on individual layers in the hosted feature layer. The following sections describe how the layer owner, or an administrator, can manage the settings for a hosted feature layer and the layers it contains.

Tip:

When you enable the following settings, anyone who can access your hosted feature layer can use the functionality the settings impart. Take this into consideration when you share your layer.

  • Enable Sync (required for offline use and collaboration)—Use a hosted feature layer offline or in a collaboration.
  • Allow others to export to different formats—Export data from the hosted feature layer.
  • Enable attachments—Add attachments to features in hosted feature layers.

Also be aware that when you share a hosted feature layer with a shared update group, group members can manage many of the settings on the layer.

Rename layers

You can change the name of hosted feature layer items and layers inside hosted feature layers.

Changing the layer names in a hosted feature layer does not affect the names in any dependent hosted layers or views. Similarly, changing the dependent layer's item name or the names of the layers in the dependent layer does not change the names in the source hosted feature layer.

  1. Sign in to the organization as the owner of the hosted feature layer or as an administrator.
  2. Open the item details page for the hosted feature layer.
  3. Rename the layer.
    • To rename the hosted feature layer, click the Edit button next to the layer name on the Overview tab.
    • To rename a sublayer, open its item page by clicking the layer name under the Layers list on the Overview tab, and click the Edit button next to the sublayer name.
  4. Type a new name for the layer and click Save.

Manage settings for editing

As the owner of a hosted feature layer, or an administrator, you can alter settings on the feature layer that affect who can edit and what edits they can make. Other factors also affect who can edit. See Manage hosted feature layer editing for information about all the settings and factors that affect who can edit a hosted feature layer.

Allow data exports

As the owner of a hosted feature layer or an administrator, you can export data from the layer to a comma-separated values file (.csv), Microsoft Excel file, shapefile, file geodatabase feature class, GeoJSON file, feature collection, or Open Geospatial Consortium (OGC) GeoPackage file. You can also configure a hosted feature layer to allow others to export data from the layer when they access it in the portal.

Tip:

If you publish a hosted feature layer from ArcGIS Pro, you can configure the feature layer to allow data exports when you publish.

When users other than the owner or administrator export from a hosted feature layer view that has field or feature definitions applied, the exported file only contains those fields or features that the definition allows. When the owner or administrator exports, the definitions are not applied and the exported file contains all fields and features.

Follow these steps to allow others to export from a hosted feature layer or hosted feature layer view when they access the layer in the portal website:

  1. Sign in to the organization as the owner of the hosted feature layer or as an administrator.
  2. Open the item details page for the hosted feature layer.
  3. Click the Settings tab.
  4. Scroll to the Feature Layer Settings section.
  5. Click Allow others to export to different formats and click Save.

Now other members of your organization can export from the hosted feature layer.

Note:

This setting does not affect others' ability to export data from the underlying service. Even if you do not enable this export setting on your feature layer, anyone who accesses this layer in other clients—such as ArcGIS Pro or custom apps—can export data from it.

Allow attachments

You can allow editors to attach images and other files to individual features in a layer in a hosted feature layer. This allows you to associate documentation or photos to specific, relevant features. For example, a code compliance officer can attach a photo of the code violation for a specific address point, or a building inspector can include a PDF of a permit for a building feature.

Each hosted feature layer view inherits the attachment setting of the hosted feature layer from which it was created. By default, all view users can see the attachments inherited from the hosted feature layer. To control who has access to these attachments, you can hide the attachments in the hosted feature layer view.

Each file you attach to a feature can be a maximum size of 2 GB. To attach files larger than 2 GB, you can use the Upload Part and Add Attachment operations from ArcGIS REST API to do a multipart upload.

For a list of supported file types you can attach, see Edit tables.

Follow these steps to allow people to attach files to features in a layer in your hosted feature layer:

  1. Enable editing on the hosted feature layer.

    If you do not enable editing, users cannot add attachments to the layer.

  2. Open the feature layer's details page by clicking the layer on the My Content tab of the content page.
  3. Click the name of the layer in the Layers list on the Overview tab to open its details page.
  4. Click the Enable Attachments toggle button.

Now, when others edit the layer, they can attach files to individual features.

If you decide you no longer want any files to be attached to your layer, open the sublayer's details page and disable the toggle button next to Enable attachments. Be aware, though, that this removes all existing attachments from the layer and prevents people from adding any more attachments.

Hide attachments in views

Hide attachments in hosted feature layer views if a subset of users need access to the feature attributes, but they should not see or do not require access to the attachments.

For example, if the attachment contains sensitive information that only a few organization members should see, share the hosted feature layer with a group that contains those few members. Create a hosted feature layer view from the layer, hide the attachments, and share the view with a larger audience.

Follow these steps to hide attachments on individual layers in a hosted feature layer view:

  1. Sign in to the organization as the owner of the hosted feature layer view or as an administrator.
  2. Open the item details page for the hosted feature layer view.
  3. Locate the Layers list on the Overview tab and click the layer that has attachments you want to hide.
  4. Click the Hide attachments toggle button to prevent users of the hosted feature layer view from accessing the attachments on that layer.
  5. Repeat steps 2 and 3 for each layer that has attachments you don't want users to access through the view.

If you decide view users do need access to the attachments for one or more of the layers in the view, click the Show attachments link under the applicable layers on the Overview tab of the hosted feature layer view's details page.

Enable time settings

If you have a hosted feature layer that records different information for the same location based on a date and time, you can enable time settings on layers in a hosted feature layer. Once time settings are configured and you add the hosted feature layer to a map, you can configure time settings on the map and see what happened at a specific time or visualize patterns and trends that emerge as the data changes over time.

Overwrite hosted feature layers

To update the data in hosted feature layers published from a file geodatabase, shapefile, GeoJSON file, Microsoft Excel file, or .csv file, replace the data with data from an updated source file by clicking Update Data > Overwrite Entire Layer on the layer's item page. For example, if your hosted feature layer is public and you don't want it to be editable, or if another department regularly sends you data updates in a shapefile, you can overwrite the data in the hosted feature layer. This maintains the URL, layer properties you set on the hosted feature layer's item page, symbology, and pop-up configurations.

When you overwrite the data, both the source file and the hosted feature layer data are replaced with the data from the updated source file. If the source is a shapefile with metadata or a file geodatabase that contains feature classes with metadata, the portal adds or replaces the layer-level metadata in the hosted feature layer.

You must use the same source file type and schema when you overwrite a hosted feature layer.

If the Overwrite option isn't available, your hosted layer cannot be overwritten due to one of the following conditions:

  • It was published from a client other than the ArcGIS Enterprise portal. For example, if you published the hosted feature layer from ArcGIS Pro, overwrite the service from ArcGIS Pro.
  • It was published while the portal was at version 10.4.1 or earlier.
  • Synchronization is enabled on the hosted feature layer.
  • It's a hosted feature layer view rather than a primary hosted feature layer. To update the data in both the hosted feature layer view and hosted feature layer from which it was created, overwrite the hosted feature layer and the updates will be reflected in the view.
  • You deleted the associated source file.

Caution:

  • If editing is enabled on the hosted feature layer, any edits that were made to the layer data are replaced by the data from the updated source file.
  • The file, field, and feature class names must be the same as they were in the original file you uploaded.
  • The same fields and feature classes (in the case of file geodatabases) must be present in the updated file as were in the original file. For example, if you delete a feature class from the file geodatabase, or add a field to the shapefile or feature class, do not overwrite.
  • If you do overwrite and the fields and feature class names and schemas do not match, the feature layer and web maps that use the feature layer may not function as expected. If the source data schema has changed, or if you want to preserve the edits made through the hosted layer, load the shapefile, file geodatabase, Excel file, or .csv file as a new item and publish a new layer instead.
  • The data source and hosted layer must be owned by the same account. If you change the owner of one, change the owner of the other. If you do not, you can't overwrite the hosted layer.
  • If you altered the details of individual sublayers, those edits will be lost when you overwrite the hosted feature layer from a file or ArcGIS Pro.
  • The feature layer will be unavailable to other users for a brief time while the layer is overwritten.

Follow these steps to overwrite a hosted feature layer:

  1. Sign in to the organization as the owner of the hosted feature layer or as an administrator.
  2. Open the item details page for the hosted feature layer.
  3. Click Overwrite.
  4. Click Browse or Choose File (depending on your browser) and browse to the location of the source file on disk.
  5. Click Overwrite.

Append data to layers

The owner of a hosted feature layer or hosted spatiotemporal feature layer or the organization's administrator can append features to a layer in an existing hosted layer. This allows you to publish initial data, or even an empty hosted feature layer, and later add more data as it becomes available without having to overwrite the entire hosted feature layer. For example, if you have a number of employees who do inspections in the field and they gather that information in a .csv file or a custom app that writes to a shapefile, you can take the file from each inspector at the end of the day and update the hosted feature layer with the new data.

If the update file contains changes to features that are already published, you can also use the input file to update existing features. This requires that the layer and the file you use to load updates both contain a field of unique values that ArcGIS Enterprise can use to identify the feature to update. You can define a field in the sublayer of a hosted feature layer as unique from the Data tab of the layer's details page and use that field as an identifier, or use a global ID in one of the sublayers for a unique ID.

Caution:

You must ensure that the field values in the update file and the layer correctly and uniquely identify the feature to update. If the values do not, you can lose data when an update overwrites attributes for an existing feature. Update and append fails if you update results with nonunique values in a field you have identified as unique.

Field names, including the letter case, in the file you use must be identical to those in the existing feature layer. When you publish from a .csv or Microsoft Excel file that has field names with spaces, the field names in the hosted feature layer have underscores inserted between words. When you append, you must insert underscores in the field names in the file; otherwise, field names will not be identical.

You can use the following file formats to append or update data:

  • Shapefile (zipped)
  • A CSV file (.csv)—The spatial field must be provided in latitude and longitude coordinates.
  • Microsoft Excel file—The spatial field must be provided in latitude and longitude coordinates.

If your hosted feature layer is enabled for offline editing, you can only append features; you cannot update features.

Follow these steps to append and update features in a layer in a hosted feature layer:

  1. Sign in to the organization as the owner of the hosted feature layer or as an administrator.
  2. Open the item details page for the hosted feature layer.
  3. To open the details of a sublayer in the hosted feature layer, click the name of the sublayer in the Layers section of the Overview tab.
  4. Click Update Data > Append Data to Layer.
    Note:

    You can only add new data to a hosted feature layer that has synchronization or change tracking (Keep track of changes to the data (add, update, delete features)) enabled.

  5. Click Browse or Choose File (depending on your browser) and browse to the location of the source file on disk.
  6. If the file is a zipped file, choose the file format from the Contents drop-down list.
  7. Click Upload and Continue.

    When ArcGIS Enterprise finishes analyzing the input file, the Append Data dialog box appears.

  8. If the hosted feature layer contains multiple layers, choose the layer to which the data will be appended or updated.
  9. If the field names in your input file do not exactly match the fields in the layer, click Show field matching to map the fields from the file to the fields in the layer.

    The append operation drops fields that do not match.

  10. If you are only appending new features to the layer, click Apply Updates.

    ArcGIS Enterprise adds the new features to the layer. They are available in maps, scenes, and dependent WFS layers and hosted feature layer views as soon as updates are applied.

  11. If the input file contains updates you want to apply to existing features in the layer, follow these steps:
    1. Check Update existing features.
    2. Specify the fields in the input file and the layer that ArcGIS Enterprise can use to uniquely identify the features to update.
    3. To update the location of the existing features and nonspatial attributes, check Update geometry for existing features. If you do not check this option, ArcGIS Enterprise updates only the nonspatial attributes in each feature.

      Note:

      If the input file's geometry type (for example, points or lines) is different than that of the hosted feature layer, the only option available will be to update attributes for existing features.

    4. If you want the update to proceed even if the input file contains rows that are not in the layer, check Ignore features without a match.
    5. Click Apply Updates.

    ArcGIS Enterprise adds new features and updates the existing features based on your input. Changes and new features are available in maps, scenes, and dependent WFS layers and hosted feature layer views as soon as updates are applied.
