1, outlining the composition of the Digital Mapping System
Collection, input, storage, management, computing, the output
2, total station primarily by which of these components and the total station's classification?
Consists of two parts: data collection equipment, process control equipment.
Category: building block type, the overall style
3, in the total station specifications in the 3 +2 ppm * d, the significance of each parameter?
3 represents the apparatus of fixed error, ppm is parts per million (several) means, D is the total station or a range finder measured the distance between the actual value, in units of km
4, outlining principles of infra-red range finder
Do not use time and using infra-red carrier phase of the phase difference to calculate the distance.
5 to understand the encoding-degree angle-measuring plate theory (Learn)
6, degree of understanding of the dynamic grating angle measuring plate theory (Learn)
7, using the formal measurement of total station before what should be set up?
A, test site, place, coordinates, elevation, equipment Gao B, measured from the direction of C, save the file name D, measurement mode
Measurement of pre-prepared are: a, battery installation and inspection b, vertical and horizontal dial indicator dial settings
                 c, dip angle display and use of automatic compensation for leveling d, instrument parameters and settings
8, outlining the implementation of the use of total station data collection steps and the settings?
See Supplementary
9, What is the baud rate
Data transfer rate
10, total station and computer data communications when the need to set which parameters
Baud rate, data bits, calibration bits, stop bits
