I'm very new to QGIS and would like to create a vector layer and populate it with a number of polygons defined by the latitude and longitude of their vertices in degrees.
I have a base map which is raster, and QGIS seems to display the coordinates of points on this map in a metric format. I'm also fairly happy with the concept of creating a .csv file in WKT format.
My question is, how do I define the vector layer in such a way that it reads the vertices in degrees, not some metric projection?
I'm guessing I have to choose the projection of my vector layer correctly. If so, how do I do that, and which projection is correct for that?
