This would also get adjoining tiles, to fill in missing points in the
case of the interpolation window overflowing the current tile. Thus treating the raster as a surface instead as discreet points. I
believe that this would be a good option to have available for DEMs in
particular. Would this be a welcomed edition to Postgis? I have one new feature that I am working on that would benefit having this baked in. I am considering bi-cubic and bi-linear interpolation options, should I consider any others. <br><br></div>Thanks,<br><br></div>Nathaniel Hunter Clay <br></div>
