It focuses on topographic diversity (D), a measure of habitat variety based on temperature and moisture conditions. D is calculated using the multi-scale Topographic Position Index (mTPI) and the Continuous Heat-Insolation Load Index (CHILI), derived from the USGS's 10m NED DEM.

It expresses the logic that a higher variety of topo-climate\nniches should support higher diversity (especially plant) and support\nspecies persistence given climatic change.\n\nTo calculate D, the multi-scale Topographic Position Index (mTPI), being a\ndominant control of soil moisture (T), was used for measuring hillslope\nposition. The mTPI was combined with the square-root transform for\nmTPI\\\u003e0 (T') and with the standard deviation of the Continuous\nHeat-Insolation Load Index (CHILI), calculated at multiple scales (C') as:\nD = 1 - ((1-T') \\* (1-C'). It is based on the USGS's 10m NED DEM (available\nin 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\n90 meters\n\n**Bands**\n\n| Name | Min | Max | Pixel Size | Description |\n|------------|-----|-----|------------|-----------------------------------|\n| `constant` | 0\\* | 1\\* | meters | NED-derived topographic diversity |\n\n\\* estimated min or max value\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.
