Abstract
These years,with OUr national economy and the investment in basal establishment construct increasing,the highway has been developed rapidly,and many modem highways have being built in recent survey of these highways has many characters such as longer line,higher precision,short time and data sharing,.,we should add more technology content to the survey,design and construction ofthe highway to improve the modem level ofhighway’S construction-
The application of GPS to highway survey is a great technological revolution,and
its foreground is very paper studies mainly using static relative position of GPS tO build highly precise three—dimensional work of highway and using real—time kinematic position of GPS to locate and layout the same time,it
combines examples of highway survey to analyze and at the universal problem that projection distortion goes beyond the limits,this
paper brings forward that we should adopt the regional coordinate system based Gauss Projection and Lambert Projection according to tending towards and
allusion to the problem that public points are patible in of highway, the paper advances the test method using public points based two—dimensional restrict analysis of the height simulation model of ,the paper brings out dynamic adding power simulation arithmetic to improve methods
of RTK surveying and choosing of regional transform parameters are puts forward that various methods should be chose neatly in highway projects,and regional transform parameters should be updated dynamically in subsection,and
multifarious test methods should be applied synthetically to achieve full—scale quality control of RTK ,the paper advances concrete scheme about integration of highway survey.
Key words: GPS technology,RTK technology,Highway Survey,Lambert
Projection,Transform Parameter,Height simulation
