Abstract

Structure of the system includes unit for finding spatial data, unit for asynchronous calling, load-balancing unit, fault-tolerance unit, unit of compression transmission and safe transmission, unit of safety authentication and userí»s authority etc. The unit for finding spatial data is divided to node container and door container for application. Unit for asynchronous calling sorts data information and calls the sorted data respectively. The load-balancing unit transfers data process to multiple servers to carry out jointly. Fault-tolerance unit manages service life cycle of Web service. The unit of compression transmission and safe transmission is in use for reducing network transmission flux and raising transmission efficiency. Unit of safety authentication and userí»s authority is in use for determining userí»s ID and authority etc. Advantages are: collecting and sharing special data resources geographical distributed, and synergistic treating requests of multiple data processed.

Description

Technical field

[0001] The invention relates to the field of geological surveys, in particular to a national geological spatial data grid service system. Background technique

[0002] For a long time, China has spent a lot of financial resources to obtain various underground and ground resource data and information, and has accumulated a considerable scale of digital spatial information resources. According to preliminary calculations, China's digital basic geological spatial information is about 1250 GB, of which 40% The construction has been completed and put into independent operation services, and a series of independent data collection, comprehensive processing, and service standards have been formed. However, because the space and attribute data in the spatial database are stored separately, the operation is isolated, which brings inconvenience to the application. Moreover, even zero-dimensional data is stored in small database systems such as ACCESS, DBASE, etc., which doe...
