TOTAL ACCURACY WITH GROUND BASED SURVEY

Kern E1 and E2 electronic theodolites are being used by West Sussex CC for the production of ground survey models instead of aerial surveys, which, because of increasing costs, poor accuracy and low levels of detailed information on surface features, have made the method unattractive. An evaluation of alternatives showed that the total station of electronic theodolite, electronic distance meter and automatic data recorder provided the best solution. Once a ground survey has been completed, the data are processed on a mini-computer using the Moss survey programs. Data are converted into a digital ground model incorporating all the features noted by the surveyor. A design model can then be overlaid electronically on the ground model and ground survey drawing and grass seeding areas can be estimated from this overlay. By using the system with a remote receiver, horizontal distance, elevation difference as well as horizontal and vertical angle can be displayed on the remote receiver making setting out far easier and quicker.
