Hallo Nicklas fortunately I have linestring version of the polygon, but it seems that the linestirings are not continuous. Does st_distance still apply? Or are there any postgis function to make the polyline continuous?

Then you can use st_distance to find the shortest distance between them. Hope that helps Nicklas 2009-10-01 Surya Tarigan wrote: > > Dear list, > > I have a river polygon with polygon length about 20 km. How can I query the minimum width of the river polygon.
