Hilbert's curve
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. WebMar 17, 2009 · The square in the Hilbert plot in Figure 1C consists of 2 8 × 2 8 pixels, i.e. the data vector is folded into the square according to the 8-th iteration of the Hilbert curve.. Due to this highly symmetric construction principle, a regularly or randomly spaced arrangement of peaks results in a pattern that appears regular or random, allowing us to infer …

WebNov 28, 2016 · At the n th level, we see that the square is broken into 4 n subsquares and the polygonal approximation to the ultimate space-filling curve consists of 4 n − 1 segments of length 1 / 2 n. Thus, the length of the approximating curve at stage n is ( 4 n − 1) / 2 n. This same approach can be used to find the length of the three-dimensional ...
