Yes!!!! for each river I have an ID:
x y ID
531607,8642 3406573,946 3518
530567,965 3401814,358 460664
531187,9049 3401014,427 537535
531187,9049 3401014,427 537535
530567,965 3401814,358 460664
529428,0755 3400194,498 616208
528728,1434 3399374,569 694934
528728,1434 3399374,569 694934
528268,188 3399074,595 723726
526928,3179 3398014,687 825472
533027,7265 3392115,198 1392472
533027,7265 3392115,198 1392472
534247,6082 3390675,322 1530845
534247,6082 3390675,322 1530845
As you can see some lat-lon has just 1 ID (just one point shows that
river) some has 2 or 3 or more how I can classify and impose idl to
just connect this points together?
Any help?
Cheers
