A Portuguese-language notebook of open-data geospatial studies, maps, and methods focused on Angola, Portugal, Switzerland, and other places.

Landing page captured for the 2026-10-25 issue.

For: Readers of open-data geospatial studies
Worth noticing: The Luanda study names Landsat 9, ESA WorldCover, and spatial validation among its methods and sources.

Field notes

The collection covers three countries and separates full studies from shorter elevation notes. The featured Luanda entry lists Landsat 9, ESA WorldCover, and a regression with spatial validation; it also says dry grass heats about as much as the built area. A set of QGIS, Python, and SQL walkthroughs is marked as coming soon, rather than presented as available now.
