Efficient classification of billions of points into complex geographic regions using hierarchical triangular mesh
We present a case study about the spatial indexing and regional classification of billions of geographic coordinates from geo-tagged social network data using Hierarchical Triangular Mesh (HTM) implemented for Microsoft SQL Server.
