# Lidar Mapping

Lidar mapping uses airborne laser scanning to create highly accurate 3D point clouds of terrain, structures, and vegetation. Common applications include surveying, construction, infrastructure inspection, forestry, mining, and aggregates.

## Payload Options

### Flux LiDAR

Flux is Freefly's purpose-built lidar payload for Astro, featuring survey-grade accuracy with sensors from Livox, Hesai, or Ouster. It includes dual full-band GNSS receivers and advanced low-noise IMUs for precise georeferencing.

Key advantages:

* Quick setup and data capture
* On-site processing via iPad for immediate field verification
* Compatible with Astro, Astro Max, and Alta X Gen 2

### Hovermap ST-X and ST

The Emesent Hovermap lidars enable detailed point cloud creation and can operate in GPS-denied environments like tunnels, mines, and under bridges using real-time SLAM.

Key advantages:

* Passive mapping mode for open-air operations
* Assisted and autonomous flight modes for GPS-denied environments
* Real-time 3D modeling for obstacle avoidance

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.freeflysystems.com/ecosystem/workflows/lidar-mapping.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
