Description: In an effort to integrate information from a wide range of data sets into a single spatially referenced grid that can be used as an annotated spatial index of data layers, facilitate data discovery, and enhance research, personnel at the Kansas Biological Survey at the University of Kansas developed the Nested Hexagon Framework (NHFv2). The NHFv2 is comprised of four nested spatial scale mapping units (1 km2 Hexagons, 7 km2 Cogs, 49 km2 Wheels, and 343 km2 Rings) and currently covers all of North and Central America, with the potential to be expanded to other global extents due to its unique hierarchical number system and spatial tiling based around 5 degree by 5 degree latitude and longitude tiles. Data can be referenced to any of the spatial scales (hex, cog, wheel, ring) depending on the spatial precision and/or sensitivity of the data. The NHFv2 allows for the sharing of information without revealing the raw spatial data or precise spatial locations so that users can quickly get a summary of the features and conditions present in a given cell. The original version of the NHF had a similar nested structure, but was based around mapping cells using miles instead of kilometers. To be better suited for scientific integration and international applications, the process framework was rebuilt around a one square kilometer hexagon grid and renamed as NHFv2 to keep it distinct.
