Rocklogger is a geological tool for measuring the orientation of rock outcrops. It uses the phone's compass and orientation sensors to measure dip & dip direction, or dip & strike, in a single click.
GPS and magnetic field information can also be saved, along with details on the rock plane & type.
-Log dip & strike or dip & dip direction by placing the phone on the rock/plane in any orientation (using the rotating symbol and quick help features as guides). You can even use a wired headset as a remote control to log hard-to-reach surfaces (paid only)
-Plot logs on a map, with correct dip/strike symbols
-Plot logs on alternate basemaps from various sources including MapBox, zip files and the web (paid only)
-Plot poles or planes from logs on a stereonet, and interpret by touching the plot to find trends and intersections (paid only)
-Log the ambient magnetic field
-Launch the camera to take photos while logging. Notes and GPS data are saved to the log file. Photos are stored with the log file, and are automatically attached when you send a log via email from the browser screen
The log is saved to a .csv file, which can be sent to Excel / Mapinfo / etc for interpreting. Paid versions can also export KML files for use in Google Earth (Android or desktop version).
Taking the strike and dip of outcrops with a compass / declinometer usually takes a few minutes per rock. With Rocklogger, many measurements of an outcrop can be taken in seconds (in any orientation). It also works upside-down, eg for logging overhang in a mine.
The evaluation version is limited to saving 3 records per 3 minutes, and has the stereonet plotter, KML export and custom basemap features disabled. Rocklogger Unlocker is available for purchase to disable the evaluation version restrictions.
-Print logs and stereonet plots to PDF or other printers using Android print framework (4.4+, paid only)
-Save record remotely using button on a wired headset (paid only)
-Added some default map tile sources, and fixed a problem reading tile files from external sd cards on 4.4
-Added current location button and scale bar to map
