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/
