I need to draw a polygon shape around Tobermory and Bunnehaven, (these are situated at the top of Figure 1 below. The issue I have with this image is that I am finding it hard to geo reference. As you can see I only have Northings and Westings? and I have no idea how to convert them or plot longitude or latitude within the
georeferencer tool. So, does anyone know how to provide longitude and latitudes for this figure?
If this is not possible is there a way to just copy the image onto QGIS and essentially draw around the shapes by
creating a new shapefile and selecting
polygon data. then with my drawn polygon, place it on my basemap?
