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…
Synthetic Aperture Radar (SAR) is a remote sensing technology that uses microwave radar signals to observe Earth’s surface. Unlike optical satellites that depend on sunlight, SAR actively transmits signals and records their reflections, allowing observations day and night and even…
Volcanic eruptions can rapidly change the landscape around a volcano. Ash, lava, and other volcanic materials may cover large areas, making it difficult to assess the extent of the impact through direct observation alone. Satellite imagery provides an efficient way…
