* Note : This app uses built-in magnetometer, so iPod Touch does not provides direction of structure/device.

GeoID is a professional tool for measuring and analyzing geological structures. This application includes geological compass, stereographic projection, instability analysis and wireless data sharing.

• Features
- The clinometer works with all attitude of the device and enables user to measure any structure
- A stability indicator in the clinometer maximizes its accuracy
- Provides many options including notation type, measurement interval, avarage calculation, projection type, etc.
- Can input data manually using several input methods
- Immediate projection and analysis of selected project
- Provides stereonet-based slope stability analysis
- Supports zooming while plotting/analyzing
- Wireless data transferring via Bluetooth and E-mail
- Generates analysis reports with stereonet images and sends them by e-mail
- Supports all iOS devices
