      Basic survey using "Polygon" with Autel EVO Max4T XE

      How to setup and survey with Max4T XE

      🔷 Step-by-Step: Polygon Mission Planning (EVO Max 4T XE)

      1. Access Polygon Mission Interface

      • From the main flight screen, tap the “Polygon” icon in the toolbar or Shortcuts.

      2. Create the Polygon Area

      • Tap the center point of your target area on the map to generate an initial square.

      • Use the “+” icons to add more corners and reshape the area.

      • Drag the white points to adjust size and shape.

      • Use the cross-arrow icon to reposition the entire polygon.

      3. Set Mission Parameters

      Once the area is defined, a menu will appear:

      • Gimbal Model and Camera Lens: Choose the payload(s) to use.

      • Mission Name: Name your mission.

      • Altitude: Set flight altitude (20–800m or ft, depending on unit format).

      • Relative Height: Adjust based on takeoff elevation.

      • Flight Speed: Set operational speed.

      • Finish Action: Select what happens after mission ends (Auto RTH or Hover).

      • Signal Loss Action: Choose behavior on disconnection (Continue or Auto RTH).

      4. Advanced Settings (Optional)

      Configure for data quality or coverage:

      • Front Overlap / Side Overlap (10–90%)

      • Main Course Angle

      • Gimbal Pitch

      • Double Grid (adds 90° second pass)

      • Route Extension

      • Elevation Optimization

      • Coordinated Turns (smooth arcs instead of hard corners)

      5. Review and Pre-Flight Check

      • Tap the ✔ check icon to open the Pre-Flight Check.

      • Confirm status:

        • Battery

        • GNSS

        • SD Card

        • Obstacle Avoidance Settings

      ➤ To configure Obstacle Avoidance:

      • Tap Menu (☰) → Settings → OA (Obstacle Avoidance)

        • Enable/Disable obstacle sensors: Forward, Backward, Up, Down

        • Set behavior: Bypass, Brake, or Off

        • Adjust Detection Range to customize how far the aircraft looks for obstacles

      Tip: Use Brake in tight spaces for safety. Use Bypass in open terrain to maintain mission flow.

      6. Execute the Mission

      • Tap “Slide to Takeoff”.

      • The aircraft will rise to mission altitude and begin flying the polygon scan path.

      7. Pause or Exit

      • Use onscreen icons to:

        • Pause: Hover in place

        • Exit: Return to home (Auto RTH)

       

      Something to remember, on the Autel app, it will only let you map 500 acres at a time.
