Problems solved by technology

[0006] Existing methods each have their own focus, but often rely on specific GIS software, rely on specific operating systems, and cannot support clusters and parallel computing environments. These methods focus on database operations for geographic information, so they are not flexible enough, because the actual geographic information file formats and spatial computing needs are varied

Abstract

The invention discloses a method for building a distributed space computation service node and a gateway device for fusing various platforms to provide the space computation service. The method comprises the following steps: performing asynchronous call on space computing resources based on a Web service structure; according to the order of first in first out, responding to an event in a multithreading mode, and realizing corresponding functions of the event; configuring a connector actually connected with the computing resources through configuring a file, and realizing the connection with the actual computing resources. The owner of the space computing resources can simply provide the owned computing resources on different platforms and systems, and the space computing resources are subjected to servitization by a node building tool to form the space computing service with unified self-described interfaces.

Description

technical field [0001] The invention relates to a Web geographic information system (GIS) and a Web remote sensing technology, in particular to a method for constructing a distributed space computing service node and a gateway device. Background technique [0002] Although the existing development methods and systems based on geographic information network service framework have their own advantages and disadvantages, most of them depend on specific GIS software, and some even rely on specific operating systems, which cannot support cluster and parallel computing environments. [0003] The existing development technology based on the geographic information network service framework includes the database used to develop the geographic information system network service framework, and the database contains spatial data. In addition, the GIS web service framework provides a GIS web service to users. GIS-based functions are web services combined with geographic information syst...
