Now available in a special "HD" version for iPad 2, Theodolite is a multi-function augmented reality app that serves as a compass, GPS, map, zoom camera, rangefinder, and two-axis inclinometer. Theodolite overlays real time information about position, altitude, bearing, and horizontal/vertical inclination on the iPad’s live camera image, like an electronic viewfinder. Uses are endless, and the app is great for hiking, boating, hunting, golf, sports, sightseeing, navigation, and finding your way around.
Theodolite has been featured numerous times in iTunes in "Rewind 2010: Hot Trends in Apps", "The World Around You", and "New and Noteworthy". It was the #1 selling Navigation app in December 2009 and September 2010. The app is used extensively by surveyors, geologists, architects, engineers, military personnel, and search and rescue workers around the world.
Theodolite lets you take geo-tagged camera images and screenshots directly from the app, with 2X and 4X digital zoom options, and buffered saves so you can keep shooting. You can choose to stamp geographical data and custom notes directly on the saved image for later reference. View your current position on the built in map view, with standard, satellite, and hybrid modes, compass rose, and bearings. Add and manage custom location markers right on the map.
The flagship of the series, Theodolite HD includes features for serious users like a reference angle mode, an A-B calculator for height, distance, heading, position, triangulation, and relative angles, data logging, e-mail export with KML data, system-wide clipboard integration, percent grade display, mil compass readout, optical rangefinders (including a mil-based reticle), colored lens filters to improve use in dark conditions and preserve night vision, military grid reference system (MGRS) coordinates, universal transverse Mercator (UTM) coordinates, and four latitude/longitude formats.
Theodolite HD requires an iPad 2 (see other apps in the Theodolite series — Free and Pro — for use on the iPhone and 4th generation iPod Touch). GPS functionality requires an iPad 2 with 3G. All models of the iPad 2 support compass and gyro use in the app, including compass-gyro fusion for accurate azimuth and bearing measurement.
