A masterpiece of precision and artistry: Guillaume Henri Dufour’s Topographische Karte der Schweiz (1833–1863). Created at an impressive 1:100,000 scale, this 25-sheet national map set a new standard for scientific cartography in the 19th century. Steel-engraved with extraordinary detail, it uses delicate hachures to sculpt the Alps in three dimensions—capturing Switzerland’s dramatic terrain with remarkable clarity. Centered on the Bern Observatory and produced during a period of rapid technological progress, the map supported military planning, infrastructure, and national unity.

I built "Avalanche Map" as a desktop app with @glazeapp to plan ski touring adventures! The Glaze agent just figured out how to pull the latest avalanche report from the official Swedish avalanche website - including detailed topo shading and slope angles. It supports 3d maps and can filter map output by the aspects affected by today's danger. Building niche software like this with just a few prompts is great

#MakingMapsPretty I’m developing a #QGIS tool to generalize and smooth a DEM, then generate a shaded relief and matching contour lines, all adapted to the selected level of generalization. Azimuth, height, Z-factor, and contour interval are controlled with a single click.
