Vertige horizontal
Plugin ID: 686
This plugin automatically detects horizontal and vertical lines using linestring vector layer as inputs.
Different thresholds can be set :
50% (0.5) is the default value for vertical and horizontal detections.
It means that to be detected as vertical a line has to be half wide than high.
Remainder is detected as diagonal (with a large threshold : 90% as default value).
This plugin is a very basic spatial analysis of networks.
As result, a new field hori_verti is created and reflects the detection : v for vertical, h for horizontal, d as diagonal, u as undefined.
