A WIRELESS DIGITAL COMPASS FOR FIELD GEOLOGY
The wireless digital compass allows multiple orientation measurements to be collected quickly and easily at a given location. Data can be read off the display or sent wirelessly to a hand-held computer where the data can be automatically stored in a geographical information system database and can be associated with the current position. The wireless digital compass can also permit data collection in situations of limited mobility such as while taking a measurement at a hard to reach location, or while enabling a person of limited mobility to make a measurement without needing to directly read a small display on the device.
Design and implementation issues include custom software development, wireless data transmission hardware integration, a simple user interface including visual feedback, ergonomic form factor, and a rugged weatherproof package. Technical details as well as a hardware demonstration will be presented.
