Splitting Geometries from Vertex Points with PostGIS

In this post, I will explain how you can get segments by LineString or Polygon geometry's vertex points.

You can use it if you have your own spatial table in your existing database. If you do not have a spatial table for testing, you can download the zip file I have shared below and use the patika.sql file in it.

Download ZIP • 20KB

If you open the patika.sql file with a Text Editor, you can create a spatial table by running the SQL codes in it in the Query Tool in the PgAdmin application.

After this step, all you have to do is run the SQL code below.

If you want to save this query as a different table, you can add "CREATE TABLE segments AS" to the beginning.

In case of a possible problem, you can write a comment below. I wish you success in your work.
