How to detect overlapping linestrings in PostGIS? Perhaps this will help clarify. Let's assume I run 1 mile down the street and that is stored in r1. I have another table of previous runs in s1. I want to return all runs in s1 that overlap r1. I exclude s1 data not in r1 bounding box. Then, I use Contains on a buffered version of my run to detect s1 runs that are inside that buffer. Does that help? |
