The changes mentioned last week have been finalised, and a new version of Rocklogger posted to the Android Market. This update allows you to log from any orientation, rather than using strictly the pitch of the phone. Specifically, Rocklogger calculates the steepest angle for the dip angle, and uses the direction of that angle to calculate the new dip direction/strike. This is also shown graphically by a new symbol on the logging screen (pictured).
When taking a lineation, it is necessary to measure the dip of one specific axis, rather than the steepest angle. Thus, we have kept the old mode in the new version. To switch, just change plane types. By default, lineations and plunges use the old mode, now known as axial orientation. The rest use the new mode, known as Normal orientation. You can also specify which orientation you want when adding your own planes (paid only).
When logging in axial orientation, the symbol doesn’t rotate, it simply indicates which direction the phone is dipping (vertical line) and the strike (arrow).
Stereonet plotting is coming soon.
- Take a measurement from any orientation. The phone calculates the steepest angle for the dip angle, and uses the direction of that angle to calculate the new dip direction/strike.
- Live dip/strike symbol when logging, which points down, showing the direction of the steepest angle, and has an arrow indicating the strike.
- Choose whether to log in the new mode (normal orientation), or the old mode (axial orientation, which measures pitch only), by selecting the appropriate plane type. Eg you would still require the old mode when logging plunges and lineations, so select that plane type to log in axial mode.
- Specify axial or normal orientation when defining new plane types (paid only)
- Changes to the calibration screen to reflect the new features
- Additional improvements when scrolling through photos in the edit view
There was a small error when logging perfectly horizontally in dip & strike mode, which has now been updated in v1.31.
Support has been added to devices whose default orientation is landscape (eg tablets, Droid2 Global), so that they now display and record in the correct orientation.
Finally, the orientation sensor calibration has changed, and so all existing calibration data will be erased on upgrade.
- Fixed an error when logging perfectly horizontally in strike mode
- Changed the orientation sensor calibration screen back to displaying pitch and roll in degrees
- Other changes to the calibration, which means any existing calibration data will be erased on upgrade (you should re-calibrate if you wish)
- Fixed compatibility problems with devices whose default screen orientation is landscape (such as tablets). Rocklogger should now work correctly (rather than 90° out) in portrait orientation on these devices.
