I have two layers, one which contains a polygon, and one which contains contours. Unfortunately, they have different projections.
I want to label the contours with their elevations BUT I only want the labels to be displayed within the bounds of the polygon (a site buffer), rather than all over the map.
Is it possible to do so? Will I have to make both layers the same projection, and clip the contour layer?
I've read through some of the other related answers here, but none seem to be right for what I am trying to do.
