What are the iOS map-viewing apps that are compatible with the largest number of file formats for topographic maps and trail maps? (such as those found on the USGS website)

It looks like Maps n Trax could help:
From the description, this looks like something you could use. An user guide can be found here. NB: im am not affiliated with them.
