Every week here at Geo Week News, we have been highlighting some of our favorite stories from around the internet that cover the geospatial, 3D, and AEC industries. Whether it’s a fascinating case study, insights from an industry thought leader, or deep dives into new tools, there is never any shortage of great writing and storytelling in this industry. So, below you can find links to three stories that we loved this week.
Mapping some of the world’s highest tropical glaciers
Wim van Wegen | GIM International
In a GIM International interview, explorer Klaus Thymann describes how Project Pressure used Trimble GNSS and drone photogrammetry to build the first high-precision 3D models of tropical glaciers in Uganda’s Rwenzori Mountains and Indonesia’s Puncak Jaya, hauling gear by hand to nearly 5,000 meters and waiting out days of cloud for a 90-minute flying window. The data shows Puncak Jaya’s ice has retreated 95 percent since 2002 and that Africa’s last glacier could vanish between 2030 and 2040, and Thymann is releasing it royalty-free so local researchers can track the change with consumer drones.
Agentic AI Has to Know Where It Is
Staff Writer | XyHt
Esri’s Ismael Chivite explains why AI assistants, which help GIS professionals work faster, are a different category from agentic AI, which is deliberately limited in scope so non-technical users can query geospatial data without making bad calls. He also covers how the Model Context Protocol keeps general-purpose AI agents from ignoring geography, how Esri’s weekly AI governance board vets every feature before it ships, and why agentic licensing is still unsettled.
Sydney student makes first map of Martian soils

University of Sydney PhD student Daniel Irving has built the first global classification system and map of Martian soils, sorting nearly 800 million locations into 2,000 soil classes he calls “areths.” As a proof of concept, the study scored each class for plant-growing potential and found the most promising one, Nohibareth, covers just 0.14 percent of the planet’s surface, mainly in the mid-latitudes around Tharsis, central Arabia Terra, and Elysium Planitia.
