About this map
The terrain is rendered from the Copernicus GLO-30 digital elevation model (ESA), masked to the US-DE boundary from geoBoundaries (gbOpen). Elevation statistics are computed directly from the model; peak names and researched facts are sourced and cited. See the methodology for the full pipeline.
Our area-weighted mean, computed from the Copernicus GLO-30 model, is 61 ft (18.5 m); the figure commonly cited elsewhere is 59 ft (18 m) (U.S. Geological Survey). Delaware's mean elevation is about 18 m; the page reports the area-weighted figure computed from the Copernicus GLO-30 model.
