Hi and welcome to the Lesson 14a in DMAD - Marine Mammals Research Association's second free QGIS course. This course if for beginners to intermediates. In the last lesson we looked at how we can make make our buffers look a little nicer without physically altering them,however, we can also do this in a more simple way, especially if we don't want any overlap in our layers. To follow along you'll need to use the water files below with a 1km buffer. Not sure how? Complete QGIS 2 Lesson 7 to find out! (www.dmad.org.tr/qgis-2-lesson-7).
