【Abstract】 This paper incorporated with wireless communication, high precision GPS position, and electrical map technologies, studied how to develop navigation and surveying system fitted for Yellow-River cross-section surveying based on PDA. Integrating the electrical map navigation and high precision GPS position technologies, it is convenient for looking the position of cross-section and known points. Realizing the real-time storing, computing, entering database, and so on for cross-section data, it’s good for the scene check and data safe.更多还原
