Webquick note for anyone who might be following the post: line.project(p) measures the projection point along the line from the starting node-coordinate given in the argument of LineString() method. But np = line.interpolate(line.project(p)) gives the POINT (5 7) as in global coordinates, not from the start of the line. Here the line started from (0,0). So it … WebJan 2, 2024 · Equation of a line: A x + B y + C = 0 Point on this line: D 1 ( x 1, y 1) How to find coordinates of points D 2 ( x 2, y 2) and D 3 ( x 3, y 3) lying at distance r from point D 1 on this line? geometry analytic-geometry Share Cite Follow asked Jan 2, 2024 at 13:13 Valeriy 117 6 Add a comment 2 Answers Sorted by: 1
