Building-Generalization plugin allows the user to correct angle of buildings to 90 degrees, and aligns all loaded buildings to nearest road.
Using this plugin, you are able to modify the angles of all buildings from the current layer to 90 degrees . One thing to note is the fact that are corrected only the angles with the value between 84-96 degrees . Also, after this step, the buildings are aligned with the closest road(way) .If the road is shorter than the current building, that building is not aligned.
All you have to do is one of this :
- If there is no layer created yet, select File -> New Layer . This will create a blank layer that you can edit .
- select File -> Open, then navigate to your file, select it and click the "Open" button .
- Select File -> Download from OSM
- After this, go to Tools and press " Building Generalization " - there's no need to select data from the map before pressing this menu item, because all the buildings are automatically edited .
