Yeah, this is what I've been waiting for! Topo Maps for iPad has full-resolution quads (the real USGS 24K maps with collars, not from Terraserver), and it can stitch them together when you run off the edge. Simple map management, both low- and high-resolution versions of each quad, elevation shading and coloring options, all tied together with a clean user interface. The iPad's big screen really makes a difference. I've been using some iPhone topo apps that look OK at 2X, but -WOW- this made-for-iPad app really shines! You can save on disk space by loading low-res maps for looking at gross details, then download the high-res map where or when you need it. Done with the high-res map? Click a button and it instantly downgrades to the low-res version to save space (or erase it entirely). The high-res maps are the real deal: print-quality copies of the USGS DRG TIFF originals; no JPEG artifacts here! The "iPad Screenshots" above don't do these maps justice. The pictures there are mostly high level, and lots of products look good like that. But if you're planning a cross-country hike, you want to zoom right in to see the same dots as on a printed topo--and, with this app, you can! If you want real topo maps, this is the app for that.

This app does provide you with topological maps as advertised and it does so fairly well. My reason for only three stars is that the app description misleadingly says "great for hikers". It is great for experienced hikers who just need a topological map, however, NOT for the casual hikers who expected to see hiking trails on these maps. There are very few visible on them, at least here in the Seattle area. If that's the reason why you wish to purchase it (it was mine), my recommendation is don't. If you just need topological maps of your area, then go ahead.

Great app for all geospatial iPad people

It's been my favorite iPhone app for some time and as expected it's even better on the iPad's larger screen. The program is responsive on the iPhone, but of course it's even faster on the iPad. Just like the iPhone version, downloading USGS quads is easy and convenient and the maps look great. Also, the developer has been very responsive to suggestions. Buy it.

Thank you so much, Phil! I am so glad you made this iPad version of your app. It's very handy to have these maps. Can't thank you enough!

This is the best topographical map app you can get! The cost alone is cheaper than buying one usgs topo map from the store and you can download all of them, yes that's right all of them for no extra charge. The great thing too is that you can zoom all the way in as well and they hold up (great resolution). It also has a shaded relief view which is really helpful to give you an overall idea of the land when you are zoomed out. The previous reviewer only gave it 3 stars as it seems they are not familiar with the usgs 7.5 minute topographical maps (not topological as they called them). If the maps are missing a newer trail that is not on the usgs topo map that is because the usgs hasn't updated it. I can see this as being a problem but if you buy a usgs topo map from the store it will be the same thing. This is not the app developers fault. If you can read a map and use usgs maps then this is the best app out there that you can get!
