# Tool Objective

The **Jakarto Data Downloader** is a tool that allows users to **select and download 3D point clouds** covering a specific region.

By downloading these point clouds, you obtain a **local copy** of the data, facilitating its use in other GIS software or [specialized applications](https://docs.jakarto.com/guide-data-downloader/en/file-download/integrating-downloaded-files-into-an-external-tool), independently of Jakarto's online services.

The files are provided in **COPC (Cloud Optimized Point Cloud)** format, an optimized extension of the **LAZ** format. This **compressed and structured** format allows for faster data access, especially for web dissemination use cases (such as [Jakartowns](https://app.gitbook.com/s/GtMh30Wh491RMXZjK9mg/jakartowns/raccourcis-clavier/general)), while remaining **compatible** with software that supports the LAZ format.
