I have some data that is similar to rainfall, ie. a latitude, longitude, and a Z number. It is in a point layer that is a nice clean point grid. Many Z numbers are missing in this grid.
I want to interpolate to find reasonable Z numbers. TIN, IDW,or other methods. I do not want to go into a Raster first then back out the intersections from the raster onto the point grid.
I can perform an interpolation in QGIS, but it generates a raster which I'm wanting to avoid. The goal is to perform all computation within PostgreSQL for production purposes.
Is this possible?
