I am developing a geoprocessing service.
I have a set of randomly dispersed points with known z-values and am using interpolation with a TIN to determine z-values at unknown locations.
The point sets are huge, so I would like to select a subset of surrounding points from the unknown location from which to generate a TIN.
I can buffer at fixed distances (say 10 km), however the nearest point at times may be 500 km away.
I would like a method that would allow me to buffer out from a given location, until I have a sufficient set of surrounding points to generate a TIN. A buffer tool by fixed number of points, not distance.
Any suggestions?
