Maintaining Visual Line of Sight (VLOS) is a fundamental requirement for safe and legal drone operations. But how far can you see your drone under...
Definition PPK stands for Post-Processed Kinematic, a high-precision positioning technique used in drone mapping and surveying. PPK corrects GPS data after a flight using post-processing software...
Definition PSM stands for Photogrammetric Surface Model, a 3D representation of the Earth’s surface derived from photogrammetry, the process of extracting measurements from photographs. PSMs capture...
Definition A Mobile Mapping System (MMS) is a technology that integrates LiDAR, GPS, IMU, and imaging sensors to capture highly accurate geospatial data in motion. Mounted...
Aerial mapping with drones is a game-changer for industries like agriculture, construction, and land surveying. However, optimizing coverage for accuracy and efficiency requires careful planning. The...
Definition The Leaf Area Index (LAI) is a dimensionless ratio that represents the total one-sided leaf surface area per unit of ground area. It is a...
Definition A Digital Terrain Model (DTM) is a representation of the Earth’s bare-ground surface, excluding vegetation, buildings, and other above-ground objects. It provides a detailed elevation...
Definition A Digital Surface Model (DSM) represents the Earth’s surface, including natural and man-made features such as buildings, vegetation, and infrastructure. Unlike a Digital Elevation Model...
Definition A Digital Elevation Model (DEM) is a 3D representation of terrain elevation data, typically generated from satellite imagery, LiDAR scans, or photogrammetric drone mapping. DEMs...
