Der Datensatz „Physiographic Diversity“ (Physiografische Vielfalt) enthält einen Index für die Vielfalt physiografischer Typen. Er wurde anhand des Shannon-Diversitätsindex in mehreren Maßstäben (km) berechnet: 115,8, 89,9, 35,5, 13,1, 5,6, 2,8 und 1,2. Sie basiert auf dem 10‑m-NED-DEM des USGS (in EE als USGS/NED verfügbar).
Die Datasets „Ecologically Relevant Geomorphology“ (ERGo) von Conservation Science Partners (CSP), „Landforms“ und „Physiography“ enthalten detaillierte, mehrskalige Daten zu Landformen und physiografischen (auch als Landfacetten bezeichneten) Mustern. Obwohl diese Daten viele potenzielle Verwendungsmöglichkeiten haben, war der ursprüngliche Zweck, eine ökologisch relevante Klassifizierung und Karte von Landformen und physiografischen Klassen zu entwickeln, die für die Planung der Klimaanpassung geeignet sind. Da zukünftige Klimabedingungen mit großer Unsicherheit behaftet sind und die ökologischen Reaktionen noch unsicherer sind, bietet die Bereitstellung von Informationen darüber, was sich wahrscheinlich nicht ändern wird, eine solide Grundlage für die Entwicklung robuster Klimaanpassungspläne. Die Quantifizierung dieser Landschaftsmerkmale hängt von der Auflösung ab. Daher stellen wir die höchstmögliche Auflösung bereit, die angesichts des Umfangs und der Merkmale eines bestimmten Index möglich ist.

It was calculated using the Shannon diversity index at\nmultiple scales (km): 115.8, 89.9, 35.5, 13.1, 5.6, 2.8, and 1.2. It is\nbased on the USGS's 10m NED DEM (available in EE as USGS/NED).\n\nThe Conservation Science Partners (CSP) Ecologically Relevant Geomorphology\n(ERGo) Datasets, Landforms and Physiography contain detailed, multi-scale\ndata on landforms and physiographic (aka land facet) patterns. Although\nthere are many potential uses of these data, the original purpose for these\ndata was to develop an ecologically relevant classification and map of\nlandforms and physiographic classes that are suitable for climate adaptation\nplanning. Because there is large uncertainty associated with future climate\nconditions and even more uncertainty around ecological responses, providing\ninformation about what is unlikely to change offers a strong foundation for\nmanagers to build robust climate adaptation plans. The quantification of\nthese features of the landscape is sensitive to the resolution, so we\nprovide the highest resolution possible given the extent and characteristics\nof a given index.\n\n### Bands\n\n\n**Pixel Size**\n\n270 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|------|-----|-----|------------|-------------------------|\n| `b1` | 0 | 1 | meters | Physiographic diversity |\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.
