Digital Forestry Grid in China Xu Zhang, Guang Deng Research Institute of Forest Resource Information Techniques Chinese Academy of Forestry 2007/10/16

Digital Forestry Grid Application Grid of Forest Resources and Forestry Eco-project Information (No. 2002AA104230),which is abbreviated as Digital Forestry Application Grid(namely DFG in short). Financed by high performance computer and core software item of national advanced technology R&D project Research Programs.

Digital Forestry Grid Presided by Research Institute of Forest Resource Information Techniques of Chinese Academy of Forestry Collaborates with Tsinghua University and China Remote Sensing Satellite Ground Station November October 2005 Be a component of the Chinese National GRID(CNGRID)

Protection and Development of China s Forest Resources (1999~2003), The Sixth National Forest Inventory( ) ; Forest area million ha 18.21%; Coverage is 18.21% ; Standing volume is million cubic meter

Protection and Development of China s Forest Resources Commercial forest million ha, with 5513 million cubic meter 5326 ; Plantation million ha 1505 million cubic meter.

Protection and Development of Chinas Forest Resources 7000 Total investment > RMB 700 billion Yuan. 97% Cover around 97% of Chinas counties 7000 Plantation > 70 million ha. Natural Forest Protection Program or Logging Ban

Protection and Development of Chinas Forest Resources Key Shelterbelts Programs in Such Regions as the Three North and the Middle and Lower Reaches of the basin of Yangtze River Conversion of Cropland to Forest and Grassland Program Sandification Control Program for Areas in the Vicinity of Beijing

Wildlife Conservation and Nature Reserve Development Program Protection and Development of Chinas Forest Resources

Fast-growing and High- yielding Timber Plantations Effectively improve capability to supply legal-source timber Protection and Development of Chinas Forest Resources

What is DFGs 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.

Structure of DFG Database design Application Development and Running Document s And other Resource s Forest Resource and Forest Project Data DFG process Service Interface Forestry Basic Data 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 11 th five-year program ( )for wide scope Be test bed of WGISSs 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 resource service, spatial information analysis service, online statistic computing service
