Hawley Square 6th August 2001 (12:30 - 14:30)
Digital plot on paper

A detailed survey of Hawley Square was undertaken to produce a plan drawing. An instrument called an electronic total station was used to collect the detail survey information. An electronic total station is a combination of a theodolite instrument (for measuring horizontal and vertical angles) and an electromagnetic distance measuring instrument (EDM). The information (angles and distances) collected for all the detail points in the square (e.g. trees, paths and walls etc) was recorded on the electronic total station’s on-board memory card. This information was later downloaded onto a computer at the IESSG and was edited using a software package to produce a raw plan of the square. The raw plan was transferred into an autocad software package to produce the final enhanced plan drawing.
