Some of the YKL rasters intentionally do not align or have the same extent. These rasters were not snapped to a common raster per the authors' discretion. Please review selected rasters prior to use. These varying alignments are a result of the use of differing source data sets and all products derived from them. We recommend that users snap or align rasters as best suits their own projects. - This file was created using the MesoMap system which consists of an integrated set of atmospheric simulation models, databases, and computers and storage systems. At the core of MesoMap is MASS (Mesoscale Atmospheric Simulation System), a numerical weather model, which simulates the physics of the atmosphere. MASS is coupled...
This raster represents development change agents (CAs) in the Mojave Basin and Range Ecoregion for the current (circa 2010). In the scenario-based assessment of conservation elements (CEs), this raster has been developed to represent CAs in a clear, combined format and to answer the management questions (MQs) such as, where do CAs intersect CEs? The raster contains 19 classes which represent different types of human infrastructure on the landscape. Some types are easily defined, precise footprints (pipelines, roads, energy development areas) while others are broader land cover types derived from spatial models (development, mining and refuse areas). During the construction of the layer, we observed that many CAs...

This data depicts infrastructure locations in Alaska as digitized primarily from 1:24,000, 1:63,360, and 1:250,000 USGS quadrangles. The source document that represented the newest information and best geographic location was used to capture the data. All infrastructure from the primary source document was digitized and then supplemented with the information from other source documents for additional or updated infrastructure or attributes.In addition, ISER added major rivers (those being named in the Anadromous streams catalog and > 150 km in length) and the historic Iditarod Trails for additional reference.

This dataset contains the future wind energy risk data layer, which was derived from NREL windenergy data across the ecoregion.
This data set contains current and proposed wind turbine tower locations for the Middle Rockies ecoregion. The level of accuracy of these data is unknown. No associated metadata was provided with this data layer.
This data set contains potential threat based on proximity to electrical transmission lines and cellular and wind turbine towers for the Greater Sage-Grouse in the Northwest Plains Ecoregion. This data set contains categorical values based on distances away from transmission lines and towers.
Powerlines in the western United States. Data was obtained from the ICEBMP existing utility corridors data set. These data were reprojected to USA_Contiguous_Albers_Equal_Area_Conic_USGS_version and clipped to the MAR REA boundary.
