Hello all friends,
I want to arrange all these phisical points into a logical map, but how many rows and column are not known in advance, we just know:
1. seperation can be given, for example stepX(width) =390.7，StepY(heigh) =318.8
2. some of the points' posX and posY are scaned several times, so deleting redundant data needed.
What's the method to solve this problem?
posX posY
60346 79682.2
59928.4 78089.2
60724 79044.4
61484.2 78085.9
59948.7 79045.6
61479 77767.5
60339.5 79365.1
56052.5 79061.7
56030.9 78113.6
56428.6 78425.4
56436.5 78745.9
57201.8 78106.2

57613.9 79700.8
56840.8 79699.7
57989.3 78739.6
58778.9 79692
58772 79048.6
58004.9 79692.7
56057.1 79703.9
57224.6 79381.9
56821.8 78747.1
56422.6 78111.7

58383.6 79060.5
56444.7 79384.2
57587.1 78109.3

Below is a small example to demostrate this case, just with hundreds of points
