Topo Maps US vs MyCloudBase

Download and view topographic maps covering the United States. Topographic maps are useful for recreational activities such as hiking, canoeing, camping, fishing, mountain biking, geocaching, and exploring. MAPS Choose from 2 map sources: USGS standard topographic or USGS hybrid topographic. OFFLINE Download maps for areas of interest to view them later when you don't have Internet access or you don't want to use cell data. TRACKING Use location tracking to show where you are on the map, your elevation, and the accuracy of the GPS signal. FLAGS Flags are included with map downloads. Add flags (waypoints) to the map to mark your current location or other locations. Import flags from other sources using GPX files and geocache LOC files. Share flags with others using email or AirDrop. Organize your flag types by color, for example, geocaches, trailheads, and summits. TRAILS Trails are included with map downloads. Import trails (tracks) using GPX files you find on the Internet or from your personal GPS track collection. Share trails with others using email or AirDrop. Organize your trail types by color, for example, mountain bike trails, hiking trails, and OHV trails. TRAIL RECORDING Record your own trails to show where you've been on the map, follow them later, and share with others. ELEVATION PROFILE Recorded trails include an elevation profile (distance/elevation chart). NAVIGATION Navigate to a flag by following the direction arrow that uses your compass heading. Useful for geocaching. MEASURE Measure the distance between points on the map. Note: Continued use of GPS running in the background can dramatically decrease battery life.

Learning to fly cross-country? This tool helps you answer the most important question: "Can I make it to that cloud?" MyCloudBase is a simple rangefinder that helps glider pilots—especially those new to cross-country flying—develop better distance judgment. Point your camera at a cloud base, and instantly see how far it is and how much altitude you'll lose getting there. WHY NEW XC PILOTS LOVE IT When you're starting out in cross-country soaring, estimating distances is hard. Clouds that look close might be 10 miles away. MyCloudBase takes the guesswork out by giving you real numbers you can use to make better decisions. "That cloud is 4.2 miles away" "I'll lose 1,850 feet getting there" "At my glide ratio, I can make it" Over time, you'll start calibrating your own eyes and building the intuition that experienced pilots have. HOW IT WORKS Set your cloudbase altitude (ask a towpilot or check the forecast) Set your glide ratio (start conservative—maybe 25:1 or 30:1) Point your phone at a cloud base Read the distance and altitude loss Decide: go for it, or find something closer? The green "Reachable Terrain" box shows you everything within gliding range. If the cloud base is inside the box, you can theoretically reach it. BEGINNER-FRIENDLY FEATURES Large, Easy Controls - Big picker wheels you can adjust with gloves on or in turbulence No Complex Setup - Just two settings: cloudbase height and your glide ratio Works Offline - No cell signal needed—works anywhere you fly Pre-Calibrated - Accurate right out of the box for most iPhones Visual Horizon Line - See exactly where level is, helping you understand pitch angles TIPS FOR NEW PILOTS Be conservative with your glide ratio. Your glider's best L/D might be 38:1, but in real conditions with headwinds and sink, 25:1-30:1 is more realistic. Use it on the ground first. Practice pointing at clouds from the airfield to get comfortable with the interface. Cross-check with your variometer. MyCloudBase is a planning aid, not a replacement for your instruments. A LEARNING TOOL MyCloudBase won't fly the glider for you, but it will help you learn one of the most important cross-country skills: knowing what you can reach and what you can't. With practice, you'll start making these estimates on your own—and that's when the real fun begins. Built by a glider pilot. Tested by glider pilots. Made for pilots who are ready to leave the pattern and explore.
