Got a PDF of a topographical map? Is that map 110 x 80 inches. None of the document readers in the App store can view and scroll your map with ease? We can, we are happy to work with Map files that are as large as 110 inches or 3 meters wide.

Say for example the USA Forestry Service Maps at http://www.fs.fed.us/maps which are 80 by 110 inches unfolded. Other PDF readers optimized for 8.5 by 11 inch page sizes just crash and burn when given such a map, or scrolling becomes ugly.

Many governments like Canada provide free maps http://atlas.nrcan.gc.ca

Or as an expert use http://mapbox.com to create your own specialized maps.

Note we dont supply the Maps you must find those, in PDF, TIFF or JPEG/PNG formats, but once you have them, then you can view them with ease. True off line viewing, no internet needed once you have given us the Map

So bring your OWN Maps for true, fast, effortless off-line viewing. Remember 24 hour support is available from the Support button!

We use our accelerated PDF viewing logic, and combined with our TIFF decoder we can deal most image formats. Expanding on our LargeViewer technology then means size is not a problem.

*** Bonus *** because of that we are a general purpose lightning fast PDF Reader, and can read FAXES too. So we are many apps in one.

With our integrated passive caching Dropbox Support you can host maps on your Dropbox account then read them from all your iOS devices, even when you dont have internet access.

Dont forget our OS-X helper app for LargeViewer

Pros and cons of Large Maps app for iPhone and iPad

Large Maps app good for

I never expected to ever be able to open some of my highest resolution topographicals. Who on earth has ever heard of opening a 3ftx4ft high res map on their phone? Its true: theres an app for everything. 5 stars for letting me open these and then scroll them faster than my useless laptop.
Its great their website points to our government of canada website for downloading free maps. I found the North Cicumpolar region map so detailed an so interesting, no wonder the U S A wants to change the northern boundaries to match their political economical desires. This maps was impossible to view in i.books. I had to restore my iPad after attempting to see it in i.books as it entered an endless crash me loop. Just like they claims you can view any sized map, at least anyone I could lay my hands on with this app. Some are *wall* sized!

Some bad moments

Ive had to lug maps into the kootenay mountains for surveying before, and believe you me, it isnt fun. Getting the digital maps we get to load on the iphone has been, of course, impossible. This little baby does that, and once loaded, it does it fast. I can get the detail right down to each individual power pole and well. A great app.
Wow I was blown away by the Maps found in the United Nations Environment Programme website like the Biodiversity loss: state and scenarios 2006 and 2050. In the past trying to view that on my iPhone was impossible. It might only be 5MB but when you zoomed in things turned into sloppy thick oil movements, and forget about scrolling, sometimes the tiling just never quiet, blurry, clear, blurry clear. This app brings up a crystal clear image and you can scroll about as fast as you can twist your finger. Just like they promised. Best thing for me is the Dropbox support because I can stuff the maps into the cloud, then I discovered they cache it locally so I can view things on the bus on my iPad without 3G. Just a wonderful feature.
Not sure why anyone would want to buy those apps that bundle up a single map for the same price as this one. With this app and some time in Google I can find maps for everywhere, and load them into my dropbox account or into local storage. More more cost effective, besides all the other apps seem to deal just with 24x18 inch paper sizes, not the WALL size 36MB PDF files this one is happy to work with and scrolling is soo painful with those other apps. PS bonus I discovered it reads TIF based FAX files too, feature creep I guess.
Google says there are like a million free maps out there, but until this app dealing with your normal topographical map on the iPad was a disaster. fuzzy drawing, fade in, scroll pain, crash, boom. This app is so slick, prerender magic and you can zoom scroll no problems. Best of all I can use Dropbox or the itunes connection feature to move maps around. Bonus I realized the Dropbox panel caches downloaded maps so I dont need 3G in the field to get a map up.
I just get errors and freezeups while trying to open a some topo tiffs imported via itunes. Very clunky interface. Useless.
When purchasing this App I was looking for more of a GPS App. I dident realize you had to up load the maps on to my Itunes and I am unapble to do this without an I-pad or phone. Please refund my account so I can sontinue to search for I am looking for. Thank you so very much Nancy A.Greene
