Detailed Features and Capabilities

High-Resolution Mapping: Mavic 3E

The Mavic 3E is designed for precision and efficiency in mapping and surveying. It features a 4/3 CMOS 20-megapixel camera with a mechanical shutter, ideal for capturing high-resolution aerial photographs. This drone is capable of generating precise maps and 3D models of surveyed areas, essential for accurate land use planning, construction, and environmental assessments.

The Mavic 3E, combined with the RTK accessory, provides centimeter-level accuracy for survey-grade results. This capability is critical for creating detailed topographic maps and 3D models, facilitating planning, design, and environmental assessments with high precision.

Advanced Thermal Imaging: Mavic 3T

The Mavic 3T, while not suitable for precise surveying even with an RTK module, excels in thermal imaging. It features a high-resolution thermal camera (640 x 512 @ 30Hz) that can detect overheating components, leaks, and energy inefficiencies. This makes it invaluable for inspections in low-light conditions, nighttime operations, and environments where visual inspection is challenging.

Flight Time and Portability

Both the Mavic 3E and Mavic 3T offer a flight time of up to 45 minutes, ensuring prolonged operational efficiency. Their compact, foldable designs make them highly portable, allowing for easy deployment in various locations. The drones can be quickly deployed, making them ideal for rapid response scenarios.

Zoom Capabilities

Both models boast a 56x hybrid zoom camera, enabling detailed inspections from a distance. This feature is particularly useful for infrastructure inspections, allowing operators to identify minor defects without needing to get too close to the target. The Mavic 3E’s wide camera has a 24mm equivalent focal length and 20 MP resolution, providing high-detail imaging crucial for detailed surveys.

Advanced Smart Features

The Mavic 3 Enterprise series includes several smart features that enhance operational efficiency and data accuracy:

• Split-Screen Thermal: The M3T supports 28× continuous side-by-side zoom, facilitating comparisons between RGB and thermal data.
• Point & Area Temperature Measurement: The M3T provides high-temperature alerts, color palettes, and isotherms.
• Corridor Mission Planning: Create automated flight missions for sites and pipelines by drawing a line on the map, which the software divides into mappable segments.
• Real-Time Terrain Follow: Automatically adjusts altitude when mapping areas with elevation variations without needing external elevation data.
• Smart Oblique Capture: The gimbal rotates in three directions to collect all photos needed for high-precision 3D modeling.
• Live Mission Recording: Record mission actions such as aircraft movement and gimbal orientation for future automated flights.

Applications in Various Sectors

Surveying and Mapping

• Mavic 3E: Ideal for capturing detailed aerial photographs for topographic surveys and generating accurate maps and 3D models. Its advanced positioning systems, including the RTK module, enable precise georeferencing, making it suitable for detailed land use planning and environmental assessments.
• Mavic 3T: Not suitable for precise surveying tasks due to its focus on thermal imaging.

Asset Inspection

• Mavic 3E: High-resolution camera allows for the identification of minor defects in assets, contributing to more accurate and comprehensive inspections. It is particularly useful for infrastructure inspections where high detail is required.
