If you get lost or in an emergency, YOU NEED A MAP! A map that covers the entire USA, all 50 states. A map that works everywhere even without a cell phone signal. A map that shows not just roads but also terrain, streams, lakes and other landmarks. Note: If you would prefer a small app that caches online maps covering the entire world, please see the More by GrangerFX section below and try the free Scenic Map app. Get You Need A Map if you want an offline map the entire USA as a single large download. The paid apps have built in maps with full resolution terrain. Your iPhone has a great online map but all it takes is one wrong turn and you could find yourself lost with no cell phone signal. What is the fastest way back to the highway? Should you go forwards or back? Is there a better road just a short distance away? Is there a raging stream or an steep cliff between you and the road? YOU NEED A MAP! You Need A Map is a huge application. It has to be. It contains every mountain, hill, stream, lake, pond, freeway, highway, local road and track. In addition it contains many buildings, trails, railways, points of interest and polygon features. It has everything you need to find out where you are and what is around you anywhere in the USA. Most navigation apps on the iPhone and iPad must transfer all their maps from servers on the internet. This can be slow in areas with only 2G coverage or completely unavailable in wilderness areas where a map would be most useful. You Need A Map solves this problem by storing maps directly on your iPhone or iPad. This extremely fast high quality software renderer is the first of its kind for mobile devices. If you do have a cellular or WiFi internet connect, Satellite image overlays add breathtaking detail and realism to the maps (tap preset 2 or 4 when Online Map is enabled). You can use them as you travel to see what is hidden from view at ground level. This takes moving maps to a whole new level. Tap the arrow in the toolbar to enable GPS tracking. As you move, you will generate a track file which you can replay. You can also import GPX tracks generated in other programs and play them. While recording or playing a track, the map will be centered on the current location and rotated towards the direction of travel and rendered in 2D or 3D with silky smooth animation. When playing a track, you can speed up, slow down, pause, restart or skip to the end. Send your GPX tracks to other apps or email them. Want to learn more about a map feature? Click the target icon and center it under the compass rose to display its name, feature type, urban area, state, elevation and coordinates. You will also see a bearing line back to your current GPS location or from your location to a selected waypoint. The status will display the direction and distance along with the map and GPS elevation, the track length, and your current speed and direction of travel You Need A Map uses the same code as Scenic Map and has most of the same features. These include many map customization options, customizable waypoints, direction and bearing information, a smooth scrolling moving map display while driving or flying, city search and much more. You can also get the full feature set of Scenic Map with an in-app purchase including the new online maps of the entire world. Documentation, detailed coverage maps, installation guide and blog are available on ScenicMap.com You Need A Map covers the entire USA including all 50 states Map data © OpenStreetMap and contributors under the Open Database License You Need A Map supports GPS tracking while the app is in the background. Caution: Continued use of GPS running in the background can dramatically decrease battery life.

Download USGS topographic maps of the United States and use them offline, with no account and no subscription. Topo Maps US is built for people who go where cell service doesn't: hikers, backpackers, hunters, anglers, paddlers, mountain bikers, geocachers, and anyone who wants a real topographic map in their pocket. MAPS Choose from three USGS map layers: standard topographic, aerial imagery with a topographic overlay, or plain aerial imagery. OFFLINE Tap the map squares you want and download them before you leave. Downloaded maps work with no Internet connection and use no cell data in the field. TRAILS AND POINTS OF INTEREST BUILT IN Every map download includes the trails, summits, lakes, campsites, and other named places in that area from OpenStreetMap, so you can search them by name while you're offline. TRAIL RECORDING Record where you go. Recorded trails show your path on the map with distance, elapsed time, and average speed. Recording stops automatically when you start driving, and any drive at the start or end of a trail is trimmed off. ELEVATION PROFILES Every recorded or imported trail gets an elevation profile with distance labels and color-coded grade shading. Drag along the chart to see the matching point on the map, its elevation, and the time you passed it. FLAGS Mark your current location or any spot on the map. Flags record coordinates and elevation, and you can add notes and organize them by color: geocaches, trailheads, summits, camps, and so on. NAVIGATION Pick a flag and follow the direction arrow, driven by your compass heading, with the distance remaining. Handy for geocaching and for finding your way back to camp or the car. LOCATION See where you are on the map, your elevation, speed, and the accuracy of the GPS fix. MEASURE Trace a route on the map to measure its distance, then save it as a trail to follow later. IMPORT AND SHARE Import trails and waypoints from GPX files and geocache LOC files. Share your flags and trails by email, Messages, or AirDrop as standard GPX files that work with any GPS unit or mapping software. Back up your maps and data to a computer over Wi-Fi. Designed for iPhone and iPad. Note: Continued use of GPS in the background can noticeably reduce battery life.
