Food safety has become an increasingly important issue to which our nationals pay much attention in recent years. In order to improve national food safety and strengthen monitoring of pollution sources, this project takes inventory of farmland, factory and environmental monitoring data from the Ministry of Economic Affairs, the Council of Agriculture, the Ministry of Interior, and the Environmental Protection Administration as the basic information for integrated applications. Through the collection of information on the possible sources of water pollution or waste pollution of agricultural land and the distribution of irrigation and drainage channels, the geographic information system is further applied to understand the affected area of agricultural land producing food crops. Query application service for data analysis results is planned based on GIS technology to provide spatial visual inspection. Through map positioning, one can query and view the surrounding environmental monitoring information according to administrative district, address, land registration, coordinates, or name of the factory, etc., and one can also use the monitoring conditions to query the spatial distribution of observation stations; through the comparison of aerial images of different years, it is also possible to learn about the changes of the landscape. Through this project, the purpose and relevance of waterbody and pollution source inspection (monitoring) items are also studied and analyzed, and value-added application functions such as estimation and early warning of agricultural land pollution range are evaluated.
