[postgis-users] Problem with EndPoint and Touches Functions

[Jonathan Aguero]

Dear List,

I created a point file with the EndPoint function from a line file. Then a
used the touches function to count how many line segments (from the line
file previously used to create the point file) touch each endpoint.
Surprisingly, some of the points have no line segments touching them. I am
guessing there is a problem with tolerances but how can I work it around?
