Abstract: In response to the problems of lagging map updates, low utilization of geographic information resources, scattered and disorderly agricultural data, and lack of effective crop traceability methods in farm management, a WebGIS-based farmland informatization and crop traceability system was constructed based on Django framework, OpenLayers map library, PostgreSQL database, PostGIS extension tool, and GeoServer platform. The system was based on data collection and farm map construction, and its main functions included map operation, land parcel information query, dynamic display of land parcel information, path planning, crop traceability, and one map of farm information resources. The system had the characteristics of convenient operation, easy maintenance, and easy scalability, and fully considered the unique attributes and regional differences of various farms in its design, with wide applicability. This system could achieve precise control of farm maps, efficient management and visualization of farm data, and obtain complete crop traceability records. Combined with WebGIS technology, the system provided a scientific and efficient operation management system for farm managers, effectively promoting the informationization and modernization of farms.
