In QGIS I would like to get the closest points to each building I have already selected. I have layer for points (low tension poles) as well as layer for buildings, I selected some buildings which are quite many and wish to get the closest point (pole) to each building I have selected.
Is there any plugin or faster process I can use to solve the issue?
You can use the NNJoin Plugin to do this job but just make sure that your join layer is a projected CRS.
"Join attributes by nearest" will do what you want:
Takes an input vector layer and creates a new vector layer with additional fields in its attribute table. The output features will contain the selected attributes from the nearest feature, along with new attributes for the distance to the near feature, the index of the feature, and the coordinates of the closest point on the input feature (feature_x, feature_y) to the matched nearest feature, and the coordinates of the closet point on the matched feature (nearest_x, nearest_y).
Looking through the "Processing Toolbox" I see there is a Distance Tool called v.distance. It seems it will calculate the nearest elemanet in a vector map from a defined "From" to a defined "To" vector layer. Here is a snip from help file:
v.distancefinds 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'. A new vector map may be created where lines connecting nearest points on features are written
