I struggled with this lab to the point of frustration. I could not for the life of me figure out how to remove the bright blue grid lines. I tried it over Spring Break with no success then and same old, same old now.
This exercise was much easier than the past labs. My building layer is displayed at 50% transparency. My Total RMS error for uwf_n file was 5.15757 and 1.97119 for the uwf_s file.
