The land survey system is an important system in our country.It is an important means to comprehensively verify and check the country's land resources and is a major investigation of national conditions.The land change survey is an annual standing work conducted on the basis of the land survey.Its purpose is to comprehensively check the annual changes in land use and update the land survey database to ensure the current situation of the land survey results.Through land survey and land change survey,it is possible to comprehensively ascertain the current state of land use throughout the country,master the accurate data on land foundations,provide strong data support for the country's land work,and improve land survey,monitoring,and statistical systems,and strengthen land resources information service,so to meet the needs of economic and social development and land resources management.In the land change survey,the authenticity and reliability of the data are an important prerequisite for ensuring the quality of the database.The quality of the data will directly affect the results of the land change survey of this year.Therefore,only under the premise that the data is true and reliable,the results of the land change survey can be used to update the database of the land survey.In order to ensure the authenticity and reliability of the survey data,a field verification link has been set up in the annual land change survey.However,the current field verification adopts manual verification methods,which leads to tight schedules and heavy tasks.This leads to low efficiency and many mistakes.Besides,the verification process is greatly disturbed by human factors,which makes it difficult to ensure the reliability of the field verification results.Aiming at the problems above,this paper has designed the land change survey field verification system,which has carried out a comprehensive demand analysis and detailed system design for the system.The system has been implemented based on the development of mobile intelligent terminals,adding multiple features to the system related to the field verification.The system focuses on the control of the authenticity of the data.As a result,the system makes it possible to improve the authenticity and reliability of the field verification results,to reduce the work of field verification staff,to accelerate the progress of field verification,and to provide strong technical support for land change survey.
