Analyze the unique advantages of UAV remote sensing technology and discuss the feasibility of using UAV remote sensing for rapid detailed investigation of land -use.Study on the UAV remote sensing data and then expound the data processing technology . Summarize the work process of rapid detailed investigation of land -use based on the UAV remote sensing and GIS technology and fo-cus on the land information extraction , analyze the advantage of the classification method of object -oriented remote sensing image . According to the requirement of rapid detailed investigation of land -use, the building of the land-use database is analyzed deeply . This paper describe database storage structure , spatio-temporal data model and the feedback of land -use detailed investigation , which avoids the data redundancy issues and increase the proportion of valid information in the database .
