Study on spatial data dynamic integration and application based on GML

Based on the analysis of GML data format and geometry elements of GML,a GML-based spatial data dynamic integration framework was presented and the integration process was discussed.(Taking) forest data in Sui-an town,Zhangpu county,Fujian province as a case study,a GML-based dynamic integration system was implemented.It showed that GML could deliver high quality vector data on the web and dynamic integration of spatial data using GML was the most effective method to spatial data transfers,exchange and integration in the present network environments.
