LiDAR drones emit laser pulses towards the ground and measure the time it takes for the light to return after hitting various surfaces. This data is used to create highly accurate 3D models of the terrain, vegetation, buildings, and other objects within the surveyed area.

Digital representation of the bare ground surface without any objects such as buildings, vegetation, or infrastructure. It provides detailed information about the elevation, slope, and topography of the terrain across a specific area.

The process of orthorectification involves aligning the image pixels to a known map projection and terrain model, resulting in a visually accurate representation of the Earth's surface

Refers to the study and representation of the shape, elevation, and features of the Earth's surface, including natural and artificial elements such as mountains, valleys, rivers, lakes, and human-made structures.
