Azure Blob Storage

Connect to a bucket in Azure Blob Storage to browse and visualize your vector and/or raster data in Felt.

This feature is only available to customers on the Enterprise plan. To upgrade, contact sales.

1. Open New data source — from the workspace homepage, click + next to Data sources. Or from a map, click in the toolbar and choose + New data source.

2. Select Azure Blob Storage

3. Fill in the Connection Details

   1. Source Name: name of the source in Felt

   2. Blob Storage Endpoint: a URL to a bucket in Azure Blob Storage, such as https://my-account.blob.core.windows.net/my_bucket/my_prefix. If the URL contains a prefix (in this example, my_prefix), Felt will only search for objects that start with it.

   3. Credentials: see the following Authentication section below.

4. Click Connect

5. Once connected you will see a catalog of your data with previews for your new source

6. From here you can add any of these layers to your maps!

Authentication

For objects hosted in Azure Storage, provide a connection string to grant Felt access to your Azure storage account.

We recommend creating a dedicated Shared Access Signature (SAS) with only Read and List permissions. Shared Access Signatures may be created at both the storage account level and the individual container level.

Creating an account-level SAS

• In Azure Portal, navigate to Storage Accounts and click on the desired account.

• In the left-hand sidebar, open the Security + networking dropdown and click on Shared access signature.

• Create a new SAS with access to all services and resources, and limit permissions to only Read and List.

• Click on Generate SAS and connection string and copy the Connection string to paste into Felt.

Creating a container-level SAS

• In Azure Portal, navigate to Storage Accounts and click on the desired account.

• In the left-hand sidebar click on Storage browser, then click on Blob containers.

• Identify the desired container and click on the three dots (…) at the far right of its row, then click on Generate SAS.

• Create a new SAS with access to all services and resources, and limit permissions to only Read and List.

• Click on Generate SAS and connection string and copy the Connection string to paste into Felt.

When inputting the Azure Connection String into Felt there should be no additional spaces:

BlobEndpoint=https://my-account.blob.core.windows.net/;SharedAccessSignature={YOUR SHARED ACCESS STRING}

Supported file formats

Felt can read in spreadsheet, vector, and raster files from cloud storage connections. To see file formats supported see Files in our Upload Anything section.

To skip Felt's data processing and stream in large, high-resolution raster files as Cloud Optimized GeoTIFFs directly from your cloud source, see Raster infrastructure.

Raster metadata extraction

Felt can extract metadata properties from the filepaths to objects in your bucket. Learn more about Felt's Raster infrastructure feature in Organizing your raster data.
