Discussion created by sgautam on Feb 8, 2013
hello everyone,
could someone please help me in this problem? I need to create a buffer of 200m around a point. i already have a shapefile for this point. I want to make a circle of radius 200m. then i want to divide this circle into eight equal parts i.e 45 degrees. i want to overlay this circle into my satellite image and extract the values from each line. if possible how do i get each line as separare shape file. any help should be appreciate. thank you very much
