# Configuring Spatial Data Sources The spatial data source (SDS) configuration interface allows you to access information on a source as well as parameter configuration functions such as metadata, permissions, and attributes.


1	General information configured when creating the SDS.
2	SDS parameters configured when it was created. The hyperlink allows you to access the DB that contains the data.
3	Spatial information. The extent corresponds to the geographical extent of the elements contained in the SDS. When it has no elements, the values are equal to 0.
4	Update schedule. Displays scheduled updates for the SDS. Click the icon to set up an automated update.
5	JMap Cloud. This section allows you to share the vector SDS in the JMap Cloud platform. The section Sharing a vector SDS with JMap Cloud provides details on this function.
6	Attributes. This section presents a list of SDS attributes. Clicking on the name of an attribute will open a window, allowing you to configure its properties.
7	References. This section lists the projects and layers that use this SDS. A legend indicates which layers are referenced.
8	These buttons allow you to access to the Metadata and Permissions sections, to make the SDS editable (the button only appears for vector SDS), to delete it, update it or edit it.

In the case of raster SDS created from the GDAL library, the configuration interface allows you to add reference coordinate systems to the original projection system of the data. The [GDAL - Geospatial Data Abstraction Library](/e/administrator/jmap-server-administrator-manual/resources-spatial-data/raster-data-sources/gdal-geospatial-data-abstraction-library.md) section provides details on this topic.

## Attributes The attribute configuration window contains two tabs: **Metadata** and **Attribute sample**.


Metadata
Type	Indicates the attribute’s data type.
Dynamic	Indicates whether the attribute is dynamic.
SQL Type	Indicates the SQL type of the attribute data.
Indexed	Check this box to have the attribute indexed.
Title	You can change the title of the attribute. This icon allows you to provide the title in multiple languages.
Format pattern	Specify a format pattern for displaying SDS items. The pattern must follow the Java standards. This article offers more details: https://docs.oracle.com/javase/tutorial/i18n/format/decimalFormat.html.
Upon saving, recursively apply to associated layers…	By checking the appropriate boxes, you will apply the title and/or format pattern of the attribute to all layers that are associated with the SDS.

The **Attribute sample** tab displays the value of the attribute for a sample of SDS elements. This button ![](/files/YsEAtAwOlJgJxulcSGlg) in the **Attributes** section allows you to update the SDS statistics. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://docs-jmapserver-lima.k2geospatial.com/e/administrator/jmap-server-administrator-manual/resources-spatial-data/configuring-spatial-data-sources.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
