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?
This is a simple way to find the center of lines in QGis: Vector > Analysis > Mean Coordinates
This worked very nice and fast.
Points are created in another shapefile, and the attribute table already comes with the coordinates along with the Unique ID field you selected earlier.
I tried before to convert the lines into polygons, then extracting the polygon centroids, but the new solution is one step shorter.
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.
use feature vertices to point in arcmap : Arctoolbox => data management tools => Features => Feature Vertices to point => select mid point type .
