I am working with QGIS and I have two different polygons, one with municipalities and another with conservation units (from Brazil).
I need find out which Conservation units falls within 50 km from every municipality.
It would be great to create a new polygon layer only with municipalities that are close to a Conservation Unit and with an attribute called UCs that contains every Conservation Units within a 50 km distance (but also keeping the original municipalities attributes).
Have I made myself clear?
I'm using QGIS because it seems easier , but, latter on, I will read this data from R. If the calculations are performed better with R, it would be better for me.
