L'ensemble de données ALOS Landform fournit des classes de formes de relief créées en combinant les ensembles de données Continuous Heat-Insolation Load Index (CHILI) et multi-scale Topographic Position Index (mTPI). Il est basé sur le MNE DEM de l'USGS à 10 mètres (disponible dans EE sous USGS/NED).
Les ensembles de données, les reliefs et la physiographie (également appelés facettes terrestres) de la Conservation Science Partners (CSP) Ecologically Relevant Geomorphology (ERGo) contiennent des données détaillées et multiscalaires sur les reliefs et les modèles physiographiques. Bien que ces données puissent être utilisées de nombreuses façons, leur objectif initial était de développer une classification et une carte écologiquement pertinentes des formes de relief et des classes physiographiques adaptées à la planification de l'adaptation au changement climatique. Étant donné la grande incertitude associée aux futures conditions climatiques et l'incertitude encore plus grande concernant les réponses écologiques, fournir des informations sur ce qui est peu susceptible de changer constitue une base solide pour permettre aux gestionnaires d'élaborer des plans d'adaptation au changement climatique robustes. La quantification de ces caractéristiques du paysage est sensible à la résolution. Nous fournissons donc la résolution la plus élevée possible compte tenu de l'étendue et des caractéristiques d'un indice donné.

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\n10 meters\n\n**Bands**\n\n| Name | Pixel Size | Description |\n|------------|------------|------------------------------|\n| `constant` | meters | NED-derived landform classes |\n\n**constant Class Table**\n\n| Value | Color | Description |\n|-------|---------|--------------------|\n| 11 | #141414 | Peak/ridge (warm) |\n| 12 | #383838 | Peak/ridge |\n| 13 | #808080 | Peak/ridge (cool) |\n| 14 | #ebeb8f | Mountain/divide |\n| 15 | #f7d311 | Cliff |\n| 21 | #aa0000 | Upper slope (warm) |\n| 22 | #d89382 | Upper slope |\n| 23 | #ddc9c9 | Upper slope (cool) |\n| 24 | #dccdce | Upper slope (flat) |\n| 31 | #1c6330 | Lower slope (warm) |\n| 32 | #68aa63 | Lower slope |\n| 33 | #b5c98e | Lower slope (cool) |\n| 34 | #e1f0e5 | Lower slope (flat) |\n| 41 | #a975ba | Valley |\n| 42 | #6f198c | Valley (narrow) |\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.
