[geos-devel] lbgeos intersect skips first coordinates

2021-07-14 Thread Hector Nunez
Hi, I found that the I use intersects the result shows that the first coordinates is not used.Here is a sample that I did using two same geometries that shows the issue.I tested similar code in Java using JTS and I don't have this issue. // SIMPLE SIMULATION OF THE PROBLEM USING
