I'm trying to create a points in the middle of polylines. The data is now in the form of shapefile. Is there an easy way to do this? Cheers, Sanna
use feature vertices to point in arcmap : Arctoolbox => data management tools => Features => Feature Vertices to point => select mid point type .
if you have qgis;
Computes the geometric center of a geometry, or equivalently, the center of mass of the geometry as a POINT. more info
it will return you centroid of your line then you can update or set it as new column or anything.
i hope it helps you...
