Study on mine spatial data sharing model

Three-dimensional geological modeling is mainly based on mine spatial data,but most of them are isolated from each other.In order to facilitate data integration and collaborative accessing,this article researched the sharing model of mine spatial data.The model was build according to the characteristics of mine spatial data,web services and GML were used to integrated multi-source data and Ajax was used to shorten the response time of the system.After coordinate transformation,modeling,data conversion and a series of other operations,the result data were provided to the user,thus the system could facilitate mine spatial data sharing and make the system a good load balancing.
