# Custom Spatial Data Sources

You can create a custom spatial data source directly in JMap Cloud Portal, without a file and without using the API. This is useful for work groups to enable field data collection, for example.

In the **Data Sources** tab of the Data Sources section, open the **Create Data Source** menu and select **Custom Spatial Data Source**.

The window that opens allows you to configure the DS parameters.

When you click **Create**, the empty spatial DS is created and displayed in the data sources table.

## Data Source Settings

The following are the parameters for a custom DS:

<table data-header-hidden><thead><tr><th width="168"></th><th></th></tr></thead><tbody><tr><td>Name </td><td>Give a name to the spatial data source. There are no naming restrictions for resources (DS, projects, map layers) in JMap Cloud.</td></tr><tr><td>CRS</td><td>Coordinate Reference System. Select the data's projection system.</td></tr><tr><td>Attributes</td><td>Click <strong>+</strong> to add attributes to the DS. <br>Give the attribute a name. Select the attribute type. Check the box if the attribute should be indexed. <br>During DS creation, you can delete attributes using the delete icon.<br>Attributes must be indexed to be used in simple searches in JMap NG.<br>When the data source data is edited, indexes are updated automatically. When the data source is deleted, the indexes are deleted.</td></tr><tr><td>Link Attribute</td><td>Optional<br>Select the attribute used to link the source's elements to documents or <a href="/pages/WWwDeCdThcthSzXHVmhL">attachments</a>, or to establish other types of links. It should generally be unique and non-null. <br><strong>Note:</strong> If the linking attribute is modified after attachments have been added, those attachments will be deleted.</td></tr><tr><td>Description</td><td>Optional<br>You can add a description of the data source.</td></tr><tr><td>Tags</td><td>Optional<br>You can add tags that can be used to sort or filter DS. Tags are available for use with all resources (DS, projects, layers).</td></tr><tr><td>Share with My Organization</td><td>Optional<br>Check this option to automatically share your data source with organization members. Members will have <strong>View</strong> and <strong>Extract Data</strong> permissions. You can modify these in the Data Source <a href="/pages/HKcddfpuASlPKukD8et5">Permissions</a> section.</td></tr></tbody></table>
