When a satellite observes Earth, its sensor does not capture only a single point directly beneath the spacecraft. Instead, it records a continuous strip of the Earth’s surface as the satellite moves along its orbit. The width of this observed…
Earth has a curved surface, but most maps are displayed on a flat screen or sheet of paper. Map projection is the mathematical method used to transform Earth’s three-dimensional surface into a two-dimensional map. Turning a Globe into a Flat…
Open-pit mines are not designed as one continuous vertical wall. Instead, their slopes are constructed in a series of stepped levels called benches. But why are these benches necessary? 01 — Structuring the Pit Wall Benches divide the overall pit…
A hillshade map is a terrain visualization technique that uses simulated light and shadows to make the shape of the Earth’s surface easier to understand. By representing elevation through brightness and darkness, hillshade creates a three-dimensional appearance from digital elevation…
Drone mapping has become an important method for surveying, inspection, and spatial data collection. However, the quality of the results does not depend only on the drone and its sensors. Weather conditions can also have a significant impact on flight…
Satellite altimetry is a remote sensing technique that uses radar pulses to measure the distance between an orbiting satellite and Earth’s surface. By combining these measurements with the satellite’s precise position, scientists can determine surface elevation with remarkable accuracy. One…
High-accuracy positioning is essential in drone surveying, especially when the collected data will be used for mapping, engineering, construction, or mining applications. Two technologies commonly used to improve drone positioning accuracy are RTK (Real-Time Kinematic) and PPK (Post-Processed Kinematic). What…
In mining operations, extracted materials do not always move directly from the mine to processing facilities or transportation points. A stockpile serves as a temporary storage area where mined materials are collected, organized, and managed before moving to the next…
A Digital Elevation Model (DEM) is a digital representation of elevation across the Earth’s surface. By converting terrain height into structured geographic data, DEMs allow mountains, valleys, slopes, and other landforms to be measured and analyzed digitally. Turning Elevation into…
