QGIS 3 Lesson 4 - Using the AND Operator to Select Areas of Our Raster

Hi and welcome to Lesson 4 in DMAD - Marine Mammals Research Association's third free QGIS course. This course is for intermediate users and assumes previous knowledge. If you're new to GIS or haven't used it for a while then I suggest flicking through a few of our previous lessons. The angle of slope is often really important to look at in terms of survey design as generally speaking we want to run perpendicular to it. In today's lesson we're going to use the AND operator in the raster calculator to refine our raster.
