I would like to extract the joint direction from a vector layer. Joints are best described 'relaxation fractures' found on rock outcrops are are easily visible if no vegetation exists. The orientation of joints can show the local stress directions caused by faulting or other tectonic activity.
I have identified an outcrop with visible joints and marked the dominant joints as a line within a vector layer - see image. Read lines are the joint directions.
. I can see the information I need in the 'Identify Features' option but cannot extract the X1,y1 and x2,y2 information to calculate azimuths.
Are there any plugins to extract azimuths of lines in a vector shapefile within a specified polygon (I would like to extract information within specified areas rather than creating many different 'joint' shapefiles).
Thanks for any help!
