What is DFG’s functions ?

Monitoring the types of forest resources Monitoring the progress and the effective

of forestry eco-construction projects Kinds of datasets from different resources

and times Synchronous update data Sharing information

Digital Forestry Grid

Be a specialized application grid which provides supports for forest resource management and forestry eco-construction projects.

DFG provides specialization grid resource management, business logic development and running engine of grid application.

Platform Structure and Runtime Environment

Digital Forestry Grid

Simultaneously construct multi-level forestry special application system for different purposes.

DFG integrates the data resources of forestry resources and forestry eco-construction projects in four levels of state, province, city and county, covering all kinds of data, such as satellite remote sensing images, spatial vector data, thematic attribute data and etc.

Digital Forestry Grid

As an application demonstration, the forest resource monitoring system and grain for green project analysis and management system have been developed for both state and provincial levels, which are important management tools for forestry resource management and forestry eco-construction projects.

Result of Data Confusion

Digital Forestry Grid

DFG can be put into used in different patterns. Firstly, it can be an independent system for

forestry-specialized computing environment. Secondly, it can be connected to share the

existing forestry information system and running environment by grid encapsulation the data, software, computer and storage devices distributed in forestry sector.

Goals for Long Term

Connecting with the other data grid Continue pushing DFG in the 11th five-year prog

ram (2006-2010)for wide scope Be test bed of WGISS’s technology Use more data grid technology for more stability How to management mass spatial information in

grid Try to provide more grid service, such as data r

esource service, spatial information analysis service, online statistic computing service
