Due to limited land resources, efficient land-use management has become a pressing issue in Taiwan. During the past decade, a number of different land-use / land-cover change detection systems have been developed to assist in land use management. In response to utilizing administrative resources effectively, the National Land Surveying and Mapping Center (NLSC) was commissioned by the Ministry of the Interior to integrate the heterogeneous land-use monitoring system into a national scale land-use monitoring project titled “The Integration of Land-use Monitoring”. This project coordinates the existing resource plans from the Construction and Planning Agency (CPA), Water Resources Agency (WRA), and Soil and Water Conservation Bureau (SWCB). Regular, multi-temporal and large scale monitoring are conducted to detect the land-use change in this project. This project constructed a series of on-line systems to deal with related notification and report processes for land change areas. With limited human resources and manpower, field investigators can now use the change detection and field investigation data to manage land properties efficiently. The purpose of this study is to demonstrate the standard notification and investigation processes. Through the integration system the authorized units can increase their effectiveness by using the analysis results for land management and even disaster prevention. Furthermore, the units can now refer to the data and information when carrying out comprehensive plans on land-use management and decision-making for national policies in the most economical and cost-effective work process. In conclusion, the integration system will continually provide useful data and information as auxiliary references for the authorities on national land management policy.
