Surveying Instruments

A surveyor’s level: a revolving telescope on a tripod

It is fitted with cross hairs,

and spirit level

It is used by surveyors in finding points of identical elevation

Automatic digital level uses barcode technology

To get an elevation measurement from a special level rod

This produces a direct electonic reading and storage of data about elevation… Possible transcription errors are eliminated.

More expensive than a standard high quality automatic level. New digital levels have been further employed expanding their memory. When you have measured height and distance, all you have to do is aim a special code staff

Then you press a single key and the results are immediately shown on the LCD display. This way “digital” gets height and distance measurement very simple.

This system can be used as long as the cross hair is visible In low light conditions In very bright sunshine

These instruments have been designed to provide accurancy which doesn’t change in adverse environments
