Is there a possibility to determine the longest side of a polygon with QGIS? As I need to do that for hundreds of polygons I would prefer an automized method (like a plugin).
So far my idea was:
- transforming a polygon into a line
- cut it on the vertices
- measure the length
- here I became stuck, how to become the longest line without checking the whole bunch of lines one by one?
looking forward to your answer
