DESCRIPTION. v.distance finds the nearest element in vector map ( to ) for elements in vector map ( from ). Various information about the vectors’ relationships (distance, category, etc.) may be uploaded to the attribute table attached to the first vector map, or printed to ‘stdout’.
Note: A new GRASS GIS stable version has been released: GRASS GIS 7.8, available here. Updated manual page: here. NAME v.net.distance – Computes shortest distance via the network between the given sets of features.
11/29/2017 · I’m not sure why this is not working for you. Can I suggest to try in GRASS itself, standalone. Once you have it working there, then switch back to the QGIS Processing framework. Note that the output layer from v.distance is just the connector lines between the from points layer to the to lines layer. So assuming you have columns: edgeid in the points layer and id in the lines layer, and.

Pertama, Anda akan membawa polyline dan layer titik ke GRASS menggunakan modul v.in.ogr di GRASS Toolbox. Kemudian cari modul v.distance. Vektor Dari dan Ke jelas merupakan titik dan garis. Kemudian pilih Jarak ke titik terdekat … di sepanjang fitur linear.
e.g. Grass v.distance , as the output is a string and needs to be handled differently.. thats one Im stuck on specifically
