# 2 Plan Your Drone Flight
**Using DJI Pilot for Flight Planning.**
1. **Access the Flight Planning Menu:** On the DJI Pilot app, tap on the "Flight Route" icon and choose "Photogrammetry Flight."
**2.Define Flight Area:** On the map interface, draw and edit the boundaries of the area you want to capture for photogrammetry.
**3.Configure Flight Parameters:** Once the flight area is defined, navigate to the "Parameter Settings" panel on the right side of the remote controller screen. Systematically set each parameter according to your specific photogrammetry mission requirements.
**Recommended Photogrammetry Parameters:**
Select the drone model：
**Flight Height:** Set the“Route Altitude” 、Safe Takeoff Altitude”.
To prevent drone crashes, follow these guidelines for route planning and operation:
Plan a safe route: Consider the terrain and obstacles in the survey area. Set the flight height to 1.5 times the height of the tallest object to ensure ample clearance.
Suggestion: The two Altitude values are consistent to avoid safety accidents.
**Setting Return To Home:**
**Side Overlap:** Set the side overlap to 80%. This ensures sufficient image overlap for effective 3D reconstruction, capturing detailed information from different angles.
**Forward Overlap:** Set the forward overlap to 70%. This provides adequate overlap between images along the flight path, ensuring complete coverage of the target area without unnecessary redundancy.
**Maintain signal strength:** Ensure real-time signal transmission throughout the flight. Based on the DJI Mavic 3 Enterprise's transmission capabilities and the terrain features, establish an appropriate survey range. Maintain a minimum of two signal bars during data acquisition. (Refer to the diagram for DJI Mavic 3 Enterprise's transmission performance.)
**4.After setting the photogrammetry parameters, upload the flight path to the drone using the drone controller.**
Click the Save button to save the route parameter settings.
Click the“Create-Area-Route” button to upload the planned route to the drone
Turn on “Max Flight Distance” button.
Click the start button and the drone will automatically take off and execute the course.

## 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, and the optional `goal` query parameter:
```
GET https://docs.get3d.ai/user-help-center/get3d-reaction/beginners-guide/3-.1-real-time-modeling/3.1.1-project-configuration/2-plan-your-drone-flight.md?ask=&goal=
```
`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
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.
