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…
Modern agriculture increasingly relies on more than observations made directly from the ground. Satellite imagery provides a broader perspective, allowing agricultural areas to be monitored efficiently across large and often difficult-to-access regions. Satellites can capture information about crops, soil, vegetation,…
How Do We Know a Mine Is Safe? Mining is an inherently complex environment where ground conditions, weather, and operational activities can change continuously. So, how do mining teams know when an area is safe to operate? The answer lies…
A map is more than a visual representation of a place. Its reliability depends on how accurately real-world information is collected, processed, positioned, and presented. From the quality of the original data to the methods used for measurement, every stage…
