Its sort of confusing trying to put things in perspective. I have troubles trying to line up the anomolies with the areas ,ie; Zona incognito, Zona Central. On different 2d images they are in different places, for example; on pg 84 /187 it shows the area as Zona Incognito on line L4250N, Zona Incognito is not here, its way to the South. So, some of these are labled wrong and it makes it hard to assign the anomolies with the Zona,s. You can still get the picture, but use only the plot lines to put you in the appropriate Zones. You cant just get the picture by looking at individual slides,(or at least I couldn,t) you have to click the images quick to look at them like a moving picture. There is some other mislabling also, but you can correct it if you look hard enough.
