Digital Levels

The development of these levels became possible due to advances in microchip technology and image processing. The attributes of self-leveling instrumentation coupled with digital array photography and electronic image processing have generated a digital level that is very much close to being truly automatic. The instrument is operated in conjunction with a special bar-coded staff. 

This type of level has the same features as automatic levels, namely the eyepiece, the focusing knob, the compensator, the circular level bubble, tangent motion, the leveling screws and objective. This is in addition to the special features pertinent to it, i.e., a built-in solid-state “camera”, a storage module, a microprocessor, a display register and a control panel.
