Orthomosaic Maps
Utilizing drone mapping technology is a cost-efficient way to measure stockpile volumetric measurements in mines and quarries, as it can obtain data from multiple sources. Drone images are joined together to create orthomosaic maps that provide 2D geo information with high resolution accuracy. These map combine digital surface models (DSMs) with Digital Terrain Models (DTMs), allowing for slope monitoring applications like landslide mitigation or prevention. Drones offer access to useful facts not available through other traditional techniques of measurement, making them the optimal choice when seeking accurate readings on specific sites.
Point Clouds
Point clouds are collections of data points in 3D space used for drone mapping. They can be applied to generate three-dimensional models and measure distances, areas, and volumes on a survey site. This is done by recording the exact coordinates for each point within the cloud from aerial imagery taken with drones or their cameras. Despite being Accurate, inaccuracies may come into play due to resolution problems associated with either drone camera quality or environment factors like wind speed etc..
