R-tree and its varieties are the main indiecs in spatial databases. With the increasing large amount of spatial data and its complexity, traditional database management methods' processing time grows rapidly. In this paper we present a novel spatial index method that takes advantage of the parallel distributed storage system by using the Hilbert curve and MapReduce computation model. The experiment...
For human survival and sustainable development, it is urgent to improve the environment, maintain ecological balance. In order to obtain more rich and timely data, satisfy environmental monitoring and management of pollution treatment needs, we put forward the environmental monitoring and management mode based on " Cloud Computing " in networked today, which realizing the spatial data sharing...
With the increasing application of spatial information system, spatial information integration and sharing are in great urgency. In this paper, a model and a schema of spatial information integration based on REST style are proposed, the feasibility is verified. It provides the spatial information integration with a completely new solution.
During the period of increasingly economic competition, how to reduce the cost of logistics has become the focus of attention.The TPL(Third-Part-Logistics) Geospatial Information Services platform Based on SOA. Taking advantage of the SOA style, it presents different logistics enterprises the integration of information resources from distributed heterogeneous multiple source systems. By sharing and...
Improving the ability of disaster prevention and reduction is a major task which our society faces. When a disaster occurs, the freely flowing of the heterogeneous distributed spatial information and the efficient integrated sharing are the important guarantee of disaster prevention and reduction. In this paper, a new integrated idea and proposal is proposed, which is based on the Service Oriented...
It has comes to be the center stage that how to take advantage of Spatial information to reduce the cost of logistic and improve the efficiency. Based on Web Processing Service Specification, multipartite logistics information and services are integrated, the WPS-based third logistics geospatial information service pattern is built, a solution to different logistics is proposed that can help them...
