WebDec 7, 2024 · The only way to get polygons that encompass 100 addresses close to each other, is to sort the data spatially. It so happens that a property of the Hilbert Curve is that the closer two points exist along the curve, the closer their x/y coordinates are, and so I figured that I could sort addresses spatially by testing their position on a curve.

WebThe way this hilbert curve is generated and looks to be printed leaves a fractal pattern of seams that decrease in length as they depart from higher order grid pattern. So there is a big weak seam with just one bridge across it at the center of the surface in both cardinal directions, but each [1/4, 1/8, 1/16, etc.] division has double that ...
