ABSTRACT
In recent years, as the development of infrastructure, the number of projects is growing.
Mapping project is playing the role of basis and irreplaceable. Data processing is especially
important in mapping project.
The purpose of the research project is solve the problem of control systern intelligent
data processing .The main topics of the project .The topic mainly studies the data structure of
work and ;automaticlly search of the minimal independence
circuit and shortest conforms to route; automatic calculation of approximate coordinates;
caculation of observationequation coefficient; position and calculation of normal
equation; adjust value’s caculation and accuracy assess and eliminate gross; variance
component estimate; computer graphics scale and coordinate system’s setting; exhibition spot
