How do you all deal with the differences in the topo maps from way back to when more recent and the differences in the location of older buildings that might not show up late... IE I have been looking at topos from 1899.. see a building on the map... but its gone by say 1920.. the "scale" I guess you can say stays the same from the 1899 map to the 1920 map but when you get to the 40s time frame, the maps are closer in scale to the rest of the maps from 1940 ish to present day.. what are your techniques in locating these places
