 ## hexbin_4326
 
-Hexbin geometries generated in various grid spacing sizes.
+The hex grid collection is a series of hexagonal geometries and tables developed to help users view the national human settlement layers at different hexagonal aggregation levels outside of the conventional census boundaries.  The hex grid geometries were created in QGIS with the MMQGIS plugin using the Canadian boundary extents at various x grid spacings.  The reference tables are generated and contains information needed for aggregation purposes of the national human settlement layers up to the given hex grid geometry.
