Tile table. tile = side length [m], cells = number of grid cells per tile (relief wavelength ≈ tile/cells), relief = relief amplitude [m], road_width [m]; flat within flat m of the road, blending back to relief over blend m (★flat is the width at which the ground does not rise above the road even when a triangle of the ground grid overlaps the road: half the road width + the grid diagonal — for a 10 m grid 3.5 + 14.1 ≈ 18 m; with 6 m the road was buried in the ground), p_road = probability that a road crosses an edge, jitter = offset of the in-tile junction (as a fraction of the tile side), seed = world seed.
