Thanks, Simon! Från: postgis-users [mailto:[email protected]] För Simon Norris Skickat: den 30 augusti 2019 18:14 Till: PostGIS Users Discussion Ämne: Re: [postgis-users] breake lines
You probably want ST_Split(). If you are working with your previous example, one way to avoid precision problems after applying the split might be to use the linear referencing funtions to shrink the lines by your preferred tolerance. In case you haven't already seen it, this illustrates the numerical precision difficulty: https://observablehq.com/@mourner/non-robust-arithmetic-as-art On Aug 30, 2019, at 1:51 AM, [email protected]<mailto:[email protected]> wrote: Hi, What PostGIS command do I use to breake linestrings or multilinestrings using another “breaking” table including linestrings or multilinestrings, without erasing any points or adding anything from the “braking” layer?
