this is the mex equivalent of the usa usgs topo maps used by hikers etc- the most of the usa is mapped out to 1:24000 scale- without checking is 1 inch per 2000 feet- in usa 24000 scale replacing such things as 62500 scale so hikers so sometimes try to grab 62500 scale or even 250000 scale before such maps are out of print
bc they give a larger area perspective
