I much prefer kriging, which seems to better model sparse areas. https://en.wikipedia.org/wiki/Kriging https://en.wikipedia.org/wiki/Kriging too bad there are no image comparisons for those methods. Main difference - instead of sum of distances with cutoff, you make sum of values weighted by distances for each map point.
- plopz 8y agoWhat you describe sounds more like idw than kriging.
- yetihehe 8y agoIndeed, I've started with nice images on web which were described as "kriging", then went on to page about kriging, seen some general ideas and implemented what I thought would be fast, simple and work. That way I had something which looked right for my application (visualising district heating temperatures in city), but only now I know how it's really called. Still better looking that heatmap.
