Description

Stereonet Mobile is designed to help you collect, visualize, and analyze geological orientation data. It is a companion to my Stereonet program for desktop computers. As such I have tried to incorporate the basic functionality of that program, taking into account the inherent limitations of mobile devices. Some of the basic tasks that one can perform with Stereonet Mobile include:

• 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 use augmented reality to 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 lines and planes, which can be tagged using one of as many user defined data types (e.g., bedding, cleavage, slickensides, etc.) as you want

• 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

• 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

• Works on iPhones or iPads. 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.

What's New

Version 3.3.0

v. 3.3.0 -- 2018.07.22

• Angle between lines now also reports the orientation of the plane that contains the two lines.

• Angle between planes now also reports the orientation of the line of intersection as well as the strikes and dips of the acute and obtuse angle bisectors.

• The app now has a view listing "best practices" for mobile device data collection which is accessible from the Settings View.

• Cosmetic bug fixes when using dip azimuth and dip format for planes: the data list view of planes is now labeled correctly.

• When using sighting down dip, the program now reports the dip azimuth and the dip, rather than the strike and dip, on the Sighting view, because that is what you are actually measuring when sighting down dip. However, strike and dip will be recorded if you have specified that format for planes. Likewise, sighting parallel to the strike always reports strike and dip because that is what you are physically measuring. If you have specified dip and dip azimuth, your measured planes will be displayed that way once you leave the screen.

Ratings and Reviews

Very nifty

Limbripper

I’m a student and this is extraordinarily useful, thank you for making this, will recommend to other students and staff

Oh my

I'm about to start a busy field season and this app is to become a critical part of it. I'll be mapping tension crack caves in Franciscan assemblage -- prime focus on joint orientation. Might even find the slope stability calculator useful! This'll be amazing.

Appears you must explicitly save data on the data screen else if the app shutdowns per iOS, you'll need to go to Open and load the recovery file. Best practice is to save your Project early and often!

Thank you for your review. You might be interested in our manuscript documenting the accuracy of iPhones as data collection devices, how Stereonet Mobile works internally, and best practices concerning their use, available at: http://www.geo.cornell.edu/geology/faculty/RWA/programs/submitted_ms.pdf

Yes, save early and often is always a good idea with computer software. When the program is started up, I could have it load the Recovery File automatically. By the way, all of the data in the program are saved whenever you tap the Save button in either the stereonet or the sighting view. Note that, if you erase data using the trash icon button in the data view, and then save a new measurement, the recovery file will have a single reading in it, i.e., only your most recent measurement. Another best practice: move your data files off of your phone as soon as possible and archive them on your desk/lap top.

Just Super!

Excellent tool for students! Note to other misfits: If you are terrible at visualizing, or simply just struggling with structural geology lab, download this! Read the manual, super easy to use. Input the data, see, understand, commit concept to memory. Thank you Professor Allmendinger!
