Current Digital Cadastral Surveying Method Research

Abstract:

Digital Cadastral is direct application results of digital mapping technology to cadastral surveying, which could enter cadastral management system directly to accomplish city digital cadastral databases to meet needs of information-based cadastral management and digital city. With discussion of common method and technology of digital mapping, system configuration and working mode of digital mapping system were presented firstly, and then concerned contents such as survey instruments, observation methods, data collection patterns and mapping software etc. were explored. Aiming at three widely used field digital mapping methods, working pattern and mapping mode of coding mapping method, sketch mapping method and electronic plate mapping method were compared, and then surveying precision, work efficiency and existing problems were analyzed. Subsequently, concrete working flow of digital Cadastral Surveying was layout. In the end, some corresponding conclusions were gained consequently and future development trend expectation was proposed.
