     1) '''ST_AsRaster''' takes a geometry and converts it to a raster.
 
-    2) '''ST_Interpolate''' takes a point (e.g. filtered lidar points) or line geometry (e.g. digitized topo lines) coverage to interpolate pixels values between geometries. There are numerous methods of [http://en.wikipedia.org/wiki/Interpolation interpolation] and it would nice to have a generic method so we can use all of them, but we’re first targeting [http://en.wikipedia.org/wiki/Bilinear_interpolation bilinear interpolation], which will fill most needs and lay the ground for other methods. For reference, you might want to check an implementation in [http://apps.nrbook.com/empanel/index.html Numerical Recipes (chap. 3)]
