Ha ha, we did have a profile plot for dot matrix - probably based on digitized data from 1:250,000 maps. We used to have a gigantic room full of tapes with this data and if you crossed a map boundary, it would require many tape mounts, etc. - the good old days, but that sure beat taping the maps together, plotting the sites and hand picking the distances and elevations off the maps by hand. Basically the way that all microwave paths before the mid 80s were designed.
