L'ensemble de données sur la physiographie représente l'intersection spatiale des couches de données sur les formes de relief (disponibles dans EE sous ERGo/1_0/US/landforms) et la lithologie (disponibles dans EE sous ERGo/1_0/US/lithology). Elle fournit 247 combinaisons uniques sur 270 possibles. Les valeurs de chaque type sont formées en concaténant les types de relief et de lithologie (par exemple, 1101 est une forme de relief "crête" sur une lithologie "carbonatée"). Cette couche de données est parfois appelée "facettes terrestres".
La couche des formes de relief est basée sur le modèle numérique d'élévation (DEM) NED 10 m de l'USGS (disponible dans EE sous USGS/NED). La couche lithologique n'est basée sur aucun MNE.
Cet ensemble de données n'est fourni que pour les États-Unis, en raison de la disponibilité de la couche de données lithologiques, bien que ces données soient probablement disponibles pour d'autres pays.

It provides 247 unique combinations\nout of a possible 270. The values for each type are formed by concatenating\nthe landform and lithology types (e.g., 1101 is \"Peak/ridge\" landform on\n\"carbonate\" lithology). This data layer is sometimes referred to as\ncharacterizing \"land facets\".\n\nThe landforms layer is based on the USGS's 10m NED DEM (available in EE\nas USGS/NED). The lithology layer is not basen on any DEM.\n\nThis dataset is provided just for the US, because of the availability\nof the lithology data layer, though these data are likely available for\nother countries.\n\n### Bands\n\n\n**Pixel Size**\n\n90 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|------------|------|------|------------|--------------------------------------|\n| `constant` | 1100 | 4220 | meters | Landforms and lithology intersection |\n\n### Terms of Use\n\n**Terms of Use**\n\n[CC-BY-NC-SA-4.0](https://spdx.org/licenses/CC-BY-NC-SA-4.0.html)\n\n### Citations\n\nCitations:\n\n- Theobald, D.
