This morning, we released a wee enhancement to Digimap for Schools to extend the functionality of the buffer tool. You’ve been able to buffer points, creating circles of a fixed size, for a while now but users immediately wanted to be able to buffer lines as well. We’ve now enhanced the buffer tool to include buffering of lines. This enables you to enclose a digitised line with a polygon. The buffered polygon is created by specifying a distance from the line to use. The resulting buffer shows all areas within that distance from the line.
Buffering lines is very useful when investigating various subjects such as seeing which areas will be effected by the development of new road, plotting exclusion zones along rivers and ecological corridors or investigating areas that would be effected by a flooded river.
Go and have a play, it is easy to use and great fun!
