Ancillary Data

The ancillary products include a variety of data layers used in model components, or for depicting the geographic extents for which products were scaled, or for general purposes such as visual display of the model.

Version numbers used by DSL: 
3.x represents our first regional dataset as used in Natures network and is still used on some ancillary data that isn’t dependent on landcover.
5.x represents the updates released in 2020, primarily in landcover which then affected most other products.
6.x is used only for species and is compatible with 5.x landcover but also includes updated climate data thus making the species products different than the 5.x species.
