  1. Update for EPA GIS Workgroupon Superfund Geospatial Data Workgroup December 7, 2005

  2. Leadup Work: 1998 – 2003 • 1998: Preliminary work on a Superfund Geospatial Policy • Based on the Pipeline • Introduced several types of boundaries • Apparent boundary • Antecedent boundary • Security boundary • etc. • 2003/4: First version of current Superfund Geospatial Procedure • Recognized that NGDP is umbrella authority • Converted from Pipeline to data type orientation SGDP Workgroup Orientation: November 22, 2005

  3. Major Themes of SGDP • For all data types, carry through the NGDP data life cycle • Adopts Accuracy Tier structure of the NGDP • Defines roles and responsibilities of Geospatial Data Stewards • Defines Superfund-specific geospatial data specifications SGDP Workgroup Orientation: November 22, 2005

  4. Outline of SGDP SGDP Workgroup Orientation: November 22, 2005

  5. Site Points Site Entrance Site Centroid NPL Point Points (other) Sample Points Ground Water Surface Water Sediment Soil Site Boundaries Apparent Security Legal Antecedent Operable Unit Deleted/Non-deleted Investigation & Contaminant Areas Air Ground Water, Surface Water, Surface Area, Soils, Sediments Cleanup/Removal Institutional Controls Proposed Types of Superfund Geospatial Data SGDP Workgroup Orientation: November 22, 2005

  6. Section 7.4: How SGDP Handles Data Types SGDP Workgroup Orientation: November 22, 2005

  7. Section 7.5: Superfund Spatial Data Stewardship Program SGDP Workgroup Orientation: November 22, 2005

  8. Approach for Workgroup Review and Completion • OSRTI will provide coordination, contract support • Regions will act as technical leads for different sections of SGDP, based on data life-cycle* • Data Planning • Data Collection • Points • Boundaries • Processing/Documentation • Storage/Access • Maintenance/Retirement * Inconsistencies in data life cycle stages between SGDP and NGDP Guidance to be resolved during this task. SGDP Workgroup Orientation: November 22, 2005

  9. Proposed Schedule SGDP Workgroup Orientation: November 22, 2005
