Strat Mobile is a program for iOS devices that enables you to measure and record stratigraphic sections right on your iPhone or iPad. Some of the basic tasks that one can perform with the app include: • Real time plotting of the stratigraphic section as it is being measured. • Measure sections using your know eye height as the “Jacob Staff” by sighting down dip through the device camera. The thickness of the measured interval, of course, depends directly on the dip (as well as your eye height). • Measure sections using a traditional Jacob Staff. The device can determine the strike and dip of the bedding for you with the tap of a button • Measure sections using a tape measure. You enter the tape azimuth, slope, start and end point, as well as the strike and dip of bedding, and the device will calculate the correct thickness automatically. • Automatically record, latitude, longitude, time and date for every interval measured • You can define an unlimited number of lithology types (with corresponding colors and widths) to draw your section and tag your observations • Provide basic statistics on the section measured, including the thicknesses and percentages of each lithology • See the locations of entire sections, measured intervals, and samples on a satellite image or road map. • Provide basic input and output of data using standard iOS conventions Will work on iPhones or iPads. The program will work on iPads lacking a cellular data connection but those devices have fewer sensors and thus cannot be used in automatic data collection mode.
