Surveying and Plotting Method for the River Channel Section Based on the Total Station and CASS

The watercourse section surveying has become more and more important in engineering reconnaissance nowadays, and based on ever urgent social demand for watercourse section surveying, the paper analyzed the subject of how to improve the watercourse section surveying and plotting efficiency. Through studying the opposite side surveying procedure inside the total station and the section surveying and graph plotting method in CASS, an integration of field and office working pattern for section surveying was summarized. The result shows that the working pattern can greatly improve the heretofore less uncultured section surveying and plotting method. Finally it's concluded that the integration of field and office working pattern for section surveying can effectively increase the section surveying and plotting efficiency.
