 description=Processes geological meso-structures
 about=geocouche is a GGIS plugin for processing the orientations of geological structures, based on the module apsg by Ondrej Lexa. Currently, it can: a) calculate the angles between planes stored in a layer and a reference plane, and b) create stereonets from plane/pole data stored in a point layer or directly as texts.
