Abstract:

According to the integration difficulties of the multi-sources mass isomerism and distribution 4G geological spatial data, the merits of three commonly used technologies of federated-database middleware and data-warehouse is demenstrated, geoscience data integration and management model based on data warehouse and middleware is proposed; with 10 minerals of baishan mining area in Jilin province in 2005 year as data sources, the SOA(ServiceOriented Architecture) is designed based on SQL(Structured Query Language) Server to verify. The results show that the architecture is suitable for heterogeneous distribution and network transmission condition, can satisfy the requirement of data update fast and real-time consistency condition, and is easy to implement on cloud platform.

Key words: 4G geological spatial data, data integration technology, data warehouse
