NSDI Framework - Missouri Spatial Data Information Service
The NSDI Framework Data Survey presented by: Tim Haithcoat University of Missouri Columbia From materials of: David Painter 1998 NSDI Partnership Kick-Off Meeting Charleston, SC Current Situation for Geospatial Data Nationally there is a need for several basic themes of data Where data exists, it is not widely used or shared due to its being undiscoverable Where data is needed, it does not exist, is incomplete, or out of date 2 Commonly Used Data Themes Q1: Do you use these themes of digital data? (If no, do you foresee that you might need them?) 100 90 80 70 60 50 40 30 20 10 0 Currently Use Need 3 Commonly Used Data Themes Q2: If you use digital data, do you have a substantial need for better data? Boundaries Parcels Elevations NO YES Cultural Water Transportation 0 10 20 30 40 50 60 70 80 90 100 4 1998 North American GIS Market Media Insurance State & Federal Gov't Logistics Telecommunication Construction Other Agriculture Utilities Local Government $0 $100 $200 $300 (in millions) $400 $500 $600 5 What is the framework? Data backbone for the NSDI • Data • Procedures • Technology A way to facilitate: • • • • • Production of geographic data Use of geographic data Reduction of operating costs Improve service Decision making 6 Framework Concept Within a geographic area, organizations that produce and use geospatial data Collaboratively build and maintain commonly used “framework” data To provide a common base for many uses Organizational Functions State Agencies Local Agencies Regional Agencies Federal Agencies Utilities Private Companies Governmental Units Hydrography Geodetic Control Cadastral Transportation Spatial Analysis Elevation • Data development, maintenance & integration • Data access • Data management • Coordination • Executive guidance • Resource management • Monitoring & response Digital orthoimagery Boundaries Base for Other Data Finished Maps Primary Purposes for Framework Provide a foundation to which spatial information and attributes can be added. Provide a base on which other themes can be compiled Provide the Spatial Reference for results of an analysis. 8 Provide foundation for linking spatial information and attributes Concentration of chemical X 0.0 1.0 0.3 0.0 0.7 0.7 1.0 0.0 0.3 1.0 0.7 0.7 0.0 1.0 Concentration of chemical X 9 Provide a base on which to compile other themes O1 R2 R3 U7 G1 10 Show the position of the results of an analysis Air Quality Analysis Toxic Release Inventory Wind Vectors Industry Location Demographics Areas having poor air quality 11 What Layers of Information are Currently Included? Geodetic control Digital orthoimagery Elevation data Transportation Hydrography Governmental units Cadastral (reference system and public 12 parcels) Technical Characteristics Feature-based, minimum attribution Unique feature identifiers Transactional updating Common means of referencing position Integration: • horizontally, vertically & thematically Multiple resolutions Distributed data holding Archival and use of historic data 13 Approach Provides For Data Maintenance Through Transactions Provides a means to: • Allow the update of data holdings without risking/compromising existing data investments • Minimize the effort required to update a data holding 0.3 1.0 0.7 0.7 0.0 1.0 14 Organization A Organization B Organizational Functions necessary to build & operate the framework Data Development & Maintenance Data Integration Data Access Data Management Executive Guidance Resource Management Monitoring & Response 15 Business Context “to be widely used and useful” Avoid restrictive practices: • No exclusive distribution arrangements that inhibit timely and equitable access • Avoid restrictions on reuse or redistribution of data • Charges set to recover cost of service only. Availability in nonproprietary format(s). Conform to standards. 16 Efforts to Extend Framework NSDI Partnership Program CAP & FDPP 44 projects to date 17 Efforts to Extend Framework NSGIC Survey in progress of “framework like” data available at state/local levels 18 Guide on “How to get started” Framework Introduction and Guide 19 http://www.fgdc.gov/framework/frameworkintroguide/ Characteristics for building a successful framework Based on common interests and needs Implement current “best business practices” Built from the ground up Based on good organizational selfassessment Being pro-active; know change factors, customers & opportunities 23
