Transportation networks are comprised of land (e.g. highways, roads, secondary roads, forestry roads, and trails), air (e.g. airports and airstrips), and water (e.g. rivers). Communities in the FNSB and a few outlying communities are connected by roads, but many communities in the study area are only accessible by airplane, boat, or snowmachine in winter. Included in trails were those designated under the Revised Statute (RS) 2477 of the Mining Act of 1866 that granted public right-of-way across unreserved Federal land to guarantee access as land transferred to state or private ownership. Rights-of-way were created and granted under RS 2477 until its repeal in 1976. However, trails that existed in 1976 continue...

The Watershed Boundary Dataset (WBD) defines the areal extent of surface water drainage to a point, accounting for all land and surface areas. Watershed Boundaries are determined solely upon science-based hydrologic principles, not favoring any administrative boundaries or special projects, nor particular program or agency. The intent of defining Hydrologic Units (HU) for the Watershed Boundary Dataset is to establish a base-line drainage boundary framework, accounting for all land and surface areas. At a minimum, the WBD is being delineated and georeferenced to the USGS 1:24,000 scale topographic base map meeting National Map Accuracy Standards (NMAS). Hydrologic units are given a Hydrologic Unit Code (HUC). For...

The current (2015) and long-term future (2060) landscape condition model (LCM) was modified for Aquatic Coarse-Filter CEs to develop condition scores for both the stream network and individual 6th-level hydrologic units. Landscape condition is a measurement of the impact of the human footprint on a landscape. Human modifications were categorized into different levels of impact (site impact scores) based on the current state of knowledge about the impacts of specific human land uses. An artificial stream network was calculated from the USGS National Elevation Dataset 2 Arc Second Digital Elevation Model using TauDEM. The flow direction grid and LCM grids were used to create a condition-weighted contributing area...

Some of the CYR 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. - The National Land Cover Database 2001 Land Cover 2011 Edition layer is produced through a cooperative project conducted by the Multi-Resolution Land Characteristics (MRLC) Consortium.

It is similar in concept to growing degree days in that it provides an index of heat accumulation across the growing season. Unlike growing degree days, SWI is calculated based on monthly, not daily, means and there is no adjustment...
