Field Book a data gathering tool used in geodesy

Field Book was a portable handheld tool, which helped recording gathered geodesy information. User interface was consisted of a four line LCD and a 4×4 Keyboard. It was capable of recording information on more than 30,000 points. After gathering information, data could be transmitted to the PC where an application read the data and convert it to a CAD map. I did this as a bachelor research project in which I was responsible for building the hardware.
