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…
In today’s era of spatial data and remote sensing, mapping the Earth’s surface has gone far beyond traditional paper maps. Technology allows us to create detailed 3D representations of terrain using digital elevation data. Three models commonly used in digital…
Maps are essential tools for understanding our world. But not all maps are created the same. Two of the most commonly used types are topographic maps and thematic maps. At first glance, they may look similar—but they serve very different…
Landslides are not just natural disasters—they are often predictable events if we know how to read the terrain. One of the most reliable tools for this is topographic analysis using contour and slope maps. In regions with heavy rainfall and…
In an era where land use is highly contested and environmental concerns are urgent, mining can no longer operate in the dark. While extractive industries provide key resources for economies, they also pose significant risks to ecosystems, water sources, and…
When looking at satellite imagery, the colors you see are not just aesthetic choices—they carry meaning. From red forests to black lakes and orange landscapes, satellite images are powerful tools for monitoring environmental change. But what do these colors actually…
