Source: Copernicus DEM GLO-30 Public, AWS COG 2021 release.
Nominal source resolution: 30 metres (a digital surface model, not a survey).
Tile: Copernicus_DSM_COG_10_N45_00_E007_00_DEM
Center: 45.97638889 N, 7.65861111 E.
Area: 6.4 x 4.2 km, north up, UTM zone 32N (EPSG:32632).
Vertical datum: EGM2008, metres.

Processing: bilinear reprojection to a 25 m display grid, 50 m elevation
contours, major contours every 200 m, subpixel path simplification. Border
opacity fades for composition; no invented hills or height exaggeration.
The 25 m resampling does not increase the original measurement resolution.
The sampled grid maximum is approximately 4324 m. This gridded surface model
does not reproduce the surveyed summit height. No surveyed summit height is
claimed by the homepage illustration.

Only an SVG is loaded by the web page. The original cropped samples,
projected samples, source coordinates and SHA-256 checksums are saved in
tools/data/matterhorn-dem.npz and tools/data/matterhorn-dem.json.
