PLANETARY SURFACE & SUBMERGED GEOMETRY
Terrain as Form & The Abyss
Cartologium asks: *Where is this terrain on the map?* Morphologium asks: *What is the differential geometry of this landscape?* By stripping the oceans and analyzing high-density USGS lidar and NOAA multibeam sonar, we decode how generative processes (ice, water, tectonics) produce distinct geometric signatures.
