SURVEYING EQUIPMENT ENTERS THE ELECTRONIC AGE

The article describes developments in electronic engineering, such as the laser and microprocessor, and their application in civil engineering. The two basic types of laser used are the helium-neon gas laser found in tunnelling and pipe alignment equipment, and the solid-state laser diode which emits infra-red pulses and is found in electronic distance measuring (edm) instruments. The microprocessor, which forms the central processor unit of a microcomputer, forms part of equipment designed to compute horizontal distances from measured slope distances and is also used to program laser alignment instruments. The article also describes solid-state survey equipment, which integrates survey data with map production, in which computer-drawn maps automatically show details of a site under examination. /TRRL/
