National GIS Sometimes called NSDI Vision and Technology

National GIS (Sometimes called NSDI) Vision and Technology Creating a Geospatial Framework for Collaborative Government Nat. GIS 1

Today GIS Is Very Valuable to Government Used in Many Integrated Applications Conservation Science/Modeling Land Management Natural Resources Congestion Pollution Energy Water Crime Defense/Security Agriculture/Forestry Economic Recovery Biodiversity Oceans Business Efficiency Global Warming Land Use Human Health Population Development Public Safety Urbanization National Security Emergency Management Logistics Humanitarian Relief Education Energy Facility Management Environmental Protection Law Enforcement Improving Planning, Management and Decision Making. . . Providing Critical Infrastructure Nat. GIS 2

Systematic Data Creation & Sharing. . . Has Been a Key to This Success Many Agencies Share Data as Part Of Their Core Mission ( Census Bureau / USGS / USDA. . . ) A Common Resource (Geodata. Gov) Data Clearinghouses Have Improved Access. . . But These Efforts Haven’t Resulted in a Geospatial Framework Nat. GIS 3

GIS Technology is Changing - Becoming Internet Focused Richer, Easier & More Pervasive New Styles, Patterns & Techniques New Services Web 2. 0 UGC Web Maps Real-Time Data Geodata Mashups Social Networks Mobile New Media Many Opportunities for Spreading Geography Everywhere euc 09

Governments Are Beginning to Create Geo-Services Providing Building Blocks of NSDI Standardized Open & Interoperable Easily Integrated Easy to Use Application Ready Using the Internet as a Platform Services Shared Geospatial Resources Moving from Data File Sharing to Creating Standards Based Services. . . Opening Access to Many New Users & Applications Abu Dhabi 5

Geo. Services will be Implemented Rapidly Supporting a Large Community of Users & Applications GIS Applications Gov. – Bus. Gov. – Citizen Gov. – Education Providing a Platform for NSDI GIS Services Integrating All Levels of Government. . . Supporting Open Access, Collaboration & Transparency Nat. GIS 6

A National GIS / NSDI Could Emerge A Distributed Network of Systems & Services Providing • • Quality Mapping Authoritative Data Analysis/Modeling Rich Applications . . . Integrating National, Regional & Municipal Geospatial Knowledge Nat. GIS 7

The Foundation Will be New Computing Paradigms Services Based Architecture GIS Servers / Services Sharing Mobility Web 2. 0 s—mash-ups Agility Cloud computing Extend enterprise & support real time Gov 2. 0 Integrate diverse content Efficiency and reliability

Natural Resource and Geo Spatial Information Foundation Database Exchange System Project Overview Goals And Major Content Implementation Plan Technical Architecture Application Models Nat. GIS 13

Project Overview China’s Central Government decided to develop a national System • Geospatial is one of “four information foundation databases” in China’s e-government – Essential in coming years – Needed for Economic growth and Social Development • A government regulation (2007 -17 “tenth-five” development cycle. . Facilitated and lead by the Development and Reform Commission, collaborating among related government organizations

信息��目建�及运行��体系 11 Sub Datacenters One Main Data Center— Natural Resource and Spatial Information Database Main Datacenter 1. Land mineral resource data center 2. Water resource data center 3. Resource and environment science data center 4. Ocean and oceanic satellite resource data center 5. Survey data center 6. Forest resource data center 7. Resource satellite data center 8. Satellite remote censoring data center 9. Climate and climate satellite data center 10. Military survey data center 11. Military space resource data center

Data Management Challenges • Collaborative development and maintenance the foundation data • Complexity of integrating spatial information • Diversity of data and service types • Database update is essential for mission critical applications

Major Goals and Contents • Promote the sharing and exchanging of information in government (Compliant with standards) • Establish one major datacenter and 11 sub datacenters • Provide the capability of information exchange and sharing services • Rely on government networking infrastructure • Provide services to the general public. • Support state level integrated decision making • Apply geospatial services to other e-government systems

Major Services • System Components – metadata sharing service – application services – database system – operating and management system
