Набор данных Physiography представляет собой пространственное пересечение слоёв данных о формах рельефа (доступных в EE как ERGo/1_0/US/landforms) и литологии (доступных в EE как ERGo/1_0/US/lithology). Он предоставляет 247 уникальных комбинаций из 270 возможных. Значения для каждого типа формируются путём объединения типов рельефа и литологии (например, 1101 — это тип рельефа «вершина/хребет» на основе литологии «карбонат»). Этот слой данных иногда называют характеризующим «грани рельефа».
Слой рельефа основан на 10-метровой цифровой модели рельефа NED Геологической службы США (доступной в странах Европы как USGS/NED). Слой литологии не основан ни на одной из цифровых моделей рельефа.
Этот набор данных предоставляется только для США из-за доступности слоя литологических данных, хотя эти данные, вероятно, доступны и для других стран.

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.
