Understanding of Surveying and mapping instruments, the classification of Surveying and mapping instruments, what are the commonly used surveying and mapping instruments?
The main instrument for manual mapping of large scale topographic maps on the ground. Composed of alidades, plate and the support member. If you add the electromagnetic wave distance measuring device in alidades, accelerate the progress of the work of Surveying and mapping.
Total stationTotal station by electronic theodolite, the electromagnetic wave range finder, micro computer, program module, memory and automatic recording device, fast electronic measuring instruments, recording distance and angle calculation, etc.. The total station instrument is suitable for engineering surveying and large scale topographic survey, speeding up the automation of ground survey, and tracking measurement of moving targets.
Gyro theodoliteA combination of gyroscopes and theodolites for measuring true azimuth. Gyro theodolite is mainly used for directional work of underground traverse measurement in mines and tunnels.
