This brings the public’s confusions and land disputation. There are many map information commonly used in local land offices, including cadastral maps, orthophoto map, cadastral investigation form, map of land survey, map of urban planning, digital map of doorplate, and status map etc; however, these map information are separated in various system, and cannot search those maps in one system. This wastes a lot of time in cadastral survey. For solving previous problems, this study from surveyor’s view plans―cadastral survey map data integration system‖ by using e-GNSS. In order to build up consistent coordinates and building time points, the system integrates land survey information and results with cadastral maps, and makes maintenance easier. This study takes the section of Annan and Anbei of Kouhu Township in Yunlin County as the experiment area to estimate the effectiveness of ―cadastral survey map data integration system‖ for cadastral survey.Comparing to the traditional land survey procedures, the system will preprocess land survey inquiries and field works. In existing cases, it can further simplify the procedures of land survey and increase efficiency.
