The ocean floor has long been a mystery to us, with its vast, unexplored depths and unique ecosystems. But beneath the waves lies a treasure trove of valuable minerals, including rare earths, copper, cobalt, and nickel. These minerals are crucial…
In recent years, the mining industry has entered a new era—Mining 4.0. This term refers to the integration of digital technologies, such as automation, drones, IoT, and data analytics, into mining operations. Just as previous industrial revolutions transformed manufacturing and…
Behind the sleek performance of modern technology—smartphones, electric vehicles, wind turbines—lie materials most people have never heard of: rare earth elements (REEs). Despite their name, these elements aren’t particularly rare in the Earth’s crust. What makes them “rare” is the…
Every day, satellites silently orbit above us, capturing detailed glimpses of our planet. But how do these machines in space actually take images of Earth—and how do those images end up in our hands? This article unpacks the journey: from…
As geospatial technologies evolve, professionals across industries face a common question: should we use drones or satellites for spatial data collection? This article provides a clear comparison between drones and satellites based on coverage, resolution, cost, and operational flexibility. Coverage:…
In the world of Earth observation, two major satellite missions stand out: Sentinel (from the European Space Agency) and Landsat (from NASA and USGS). Both provide open and free satellite imagery to monitor changes on the planet, but they differ…
In an era of climate uncertainty and resource challenges, satellite technology is playing a vital role in supporting those whose livelihoods depend on the earth and ocean. Farmers and fishers are leveraging data from above to make smarter, more sustainable…
Topographic maps have evolved significantly beyond traditional contour lines on paper. Today, advanced technologies enable us to generate high-resolution elevation data that support various applications, from disaster risk reduction to land-use planning. Three key tools driving this progress are LiDAR,…
Topographic visualization plays a crucial role in spatial analysis, especially when trying to understand the terrain of a given area. One of the most visually intuitive tools for this purpose is the hillshade map. But what is it, and how…
