4501.2 - Research on Integrated Vector and Raster Data Organization Model Design Under the Distributed Environment

Tuesday, July 4

Location: Delaware A

With the combination and development of geographic information technology and computer network technology, geographic information services based on global framework demand for more efficient massive data management, the traditional single center relational database management mode is unable to meet the requirements. Since the distributed file systems, semi-structured databases and relational database technology have complementary advantages to each other, a new technical method for efficient management of massive data is developed. In order to achieve high effective geospatial data management, this paper presented an integrated architecture oriented to the storage and management of geospatial data in distributed environment, designed user – oriented massive geospatial data integration model and distributed storage organization model . In this model, a technical route combining the NoSQL database and relational database is adopted, and a layered + partitioned data model and multi-level index mechanism for the rapid access of massive data is designed, so it can realizes the integrated management of vector and raster data in distributed environment. An experiment system is set up in the experiment environment, which realizes vector data and raster data management model. TB-level data are used to conduct experiments of data loading, index creation and concurrent data access efficiency, compared with the traditional data model, the model in the data management capacity, processing speed and access efficiency have greatly improved. The results show that the model can support parallel operation in distributed environment, with a higher data management capability will offer an effective solution to massive data management in distributed environment.
