Stereonet Mobile

Stereonet Mobile is designed to help you collect, visualize, and analyze geological orientation data on the go. It is a companion to my Stereonet program for desktop computers, but it can also be used to measure orientations on the outcrop. The app has the following features:

  • Provide automatic data entry as a geologist's compass by reading the iOS device orientation and converting it to strike and dip of planes and/or trend and plunge of lines. It is the only geology compass app that can record the strike and dip of planes using the sighting method and the device camera.

  • Provide manual data entry via either tapping and dragging on the stereonet or by typing values into text fields

  • Plot one group of lines and one group of planes, though individual observations can be tagged and filtered as the user wishes.

  • Carry out basic calculations such as: rotations about any axis, planes from poles or poles from planes, measure angles between lines and between planes, and basic slope stability calculations

  • Plot mean vectors, cylindrical best fits, rose diagrams, and contour lines.

  • View the plots from any orientation, not just looking straight down into the lower hemisphere

  • Stamp each entry with time date and, if enabled by the user, location. See the location of a datum in the iOS Maps program

  • Show realtime changes to the stereonet projection to help students understand the geometry of the device better

  • Provide basic input and output of data using standard iOS conventions

  • Work on both iPhones or iPads, both in portrait mode only. The program will work on iPods or iPads lacking a cellular data connection but those devices have fewer sensors and thus cannot be used in automatic data collection mode.

  • Integrated with the StraboSpot online structure and tectonics database. Make your measurements in Stereonet Mobile and upload them directly to your StraboSpot account.
