# Extensions

This section displays the extensions that add specific functionality to JMap Cloud projects.

Each extension is displayed as a card containing the following information:

* Extension name
* Publisher organization
* Version
* Description of available features
* Representative image
* Link for additional information

A toggle switch allows you to enable or disable each extension globally for your organization.

{% hint style="info" %}
For extensions to be available in **JMap NG applications**, they must be activated at two levels:

* **Organization level**: Activation makes the extension available for projects. This is done in this section: **Organization / Extensions**.
* **Project level**: Activation makes the extension available in the JMap NG application. This is done in the **Extensions** tab of the **Projects / Extensions** section.
  {% endhint %}

## Available Extensions

Available extensions and connectors may change over time.

### Dashboard

This extension displays metrics related to map data in the form of charts. Metrics are calculated from a data layer and are dynamic, meaning they are updated in real time to reflect the values of the data displayed as the user navigates the map.

### Geoselec

This extension allows users to identify available aerial images and photographs for an area of the map selected in the JMap NG application. The images are provided by [Geoselec](https://geoselec.com/en/). Their characteristics are displayed within the extension, and users can explore them. A link connects the extension to the Geoselec catalog for acquisition.

### Jakartowns

This extension opens a window for browsing data and panoramic images provided by the Jakartowns tool from [Jakarto](https://www.jakarto.com/).

### NG Configuration

This extension allows JavaScript developers to customize the mapping interfaces of the JMap NG application.

### Terrain

This extension enables the use of digital terrain model (DTM) data to perform analyses such as slope calculation, elevation, cut-and-fill volumes, and cross-sections for areas selected by the user in a JMap NG application.
