Research on Land Area Surveying Technology and Land Information System Based on Beidou/GPS Dual Mode Positioning
In order to improve the accuracy of land area surveying,reduce measurement errors,and standardize the utilization and development of land resources,the Beidou/GPS dual-mode positioning technology is used as the core and support to design and research land area surveying technology.Based on this,the development of land information systems is carried out.By calculating the distance between satellite signals and receivers,land area surveying and error compensation,the design of surveying technology is completed.Based on surveying and mapping technology,the selection of measuring instruments,wireless communication deployment of land information,acquisition and transmission of positioning information,and database connection display of land information systems are carried out to achieve the development of the system.Through testing,it has been proven that the measurement results of the designed surveying and mapping technology have a small error compared to the actual results.This error can be ignored in practical work,and the measurement results can be regarded as the true results.At the same time,the comprehensive test results show that the system developed in this article can achieve the expected design standards and effects.
