Abstract： In order to realize digital urban planning， the digital urban planning model based on WebGIS （Web Geographic Information System） is put forward. The GIS big data analysis model of digital urban planning is constructed to integrate and schedule the WebGIS big data of digital urban planning. The statistical feature extraction model of urban planning based on WebGIS is established， and the spatial positioning in the process of digital urban planning is performed based on the method of spatial information point calibration. The WebGIS data detection of digital urban planning are performed by data fusion and fuzzy C?means clustering analysis， and the big data fusion scheduling model of digital urban spatial planning is established with the piecewise fitting method to realize digital urban planning. The software of digital urban planning model system is developed with [C/S] architecture and ARM embedded technology. The system includes WebGIS information acquisition model， bus control module， database module， human?computer interaction module and data processing terminal module. The simulation results show that the digital urban planning model design based on this method has good intelligence and strong ability to access and schedule the WebGIS data.
