Point coordinates to polygon – part II

In my previous article, I showed how you can convert point coordinates into a polygon vector layer in QGIS. So how about GRASS GIS? Like in my previous post, let’s assume you have a text file with two columns with the coordinates. With the v.in.ascii function you can import this text file as a point layer. Next, you can use v.hull or v.delaunay to create polygon layers.

With a little bit more work, you can convert the above mentioned text file into a ASCII vector file.
