After we have done the drone survey of the project area for Ortho image and Digital Surface Model. All the Field survey work conducted on presence of Mining officials, Revenue Officials and Lessee.

Drone Data Processing and Mapping Drone Mapping:

Drone mapping, also known as aerial mapping or photogrammetry, is a method of creating accurate maps, models, and surveys using unmanned aerial vehicles (UAVs) equipped with cameras or sensors.
The process involves several steps:
Mission Planning: Determine the area to be mapped and plan the flight mission. Consider factors such as weather conditions, airspace restrictions, and flight parameters.
Equipment Setup: Prepare the drone and its payload, ensuring the camera or sensor is properly calibrated and functioning correctly. Set up ground control points (GCPs) if high-precision mapping is required.
