Query: Using Table Valued Functions in SQL Server 2005 To Implement a Spatial
  Data Library   This article explains how to add spatial search functions (point-near-point
and point in polygon) to Microsoft SQL Server 2005 using C# and table-valued
functions. It is possible to use this library to add spatial search to your
application without writing any special code. The library implements the
public-domain C# Hierarchical Triangular Mesh (HTM) algorithms from Johns
Hopkins University. That C# library is connected to SQL Server 2005 via a set
of scalar-valued and table-valued functions. These functions act as a spatial
index.
