Model Render Web
A 3D view of the Earth in a web browser, rendered from the global
elevation model (GDEM) data on the shared /datasets volume —
the ETOPO 2022 global relief model maintained by the
model-elevation-earth project.
Status
- Status: active.
- Data source: ETOPO 2022 (land elevation + seafloor bathymetry),
15-arcsecond GeoTIFF tiles on
/datasets/dataset-etopo-2022/. - Render: a WebGL globe — whole-globe view with a 2x detail option, and regional zoom that streams tile-pyramid detail on demand (down to 0.04 degrees per pixel).
- Live dataset state: see the dashboard.
How it works
The project reads the GDEM tiles from the shared datasets volume and
derives browser-ready assets: global hypsometric textures (0.5 and 0.25
degrees) and an equirectangular tile pyramid (z1..z5) with an index. The
globe page renders the Earth in 3D and, when zoomed, fetches only the
visible window's tiles at the matching zoom level. The approach is decided
in documents/05-render-approach.md.
