Carry geometry as geometry. GeoPBF is a compact binary container for geospatial features, with Gint — a GPU-readable topology layer for instant point-in-polygon identify, shared-edge topology and choropleth painting. Converts GeoJSON / Shapefile / KML / K

GeoPBF topological editor as a map gadget: initEditor(map, opts). Edits on the sphere (great-circle edges, rotations, small circles), @style annotations shared with the viewer (geopbf/edit/draw), large-file mode on GintBUF — the editor half of the geopbf

Serverless, dependency-free 3D globe of Japan for any web page — GSI vector tiles and MLIT PLATEAU buildings drawn on a true sphere with WebGPU/WebGL2. No API keys, no billing, no servers.
