4. Feasibility of The National Map to Drive Web-Based Environmental Models The National Map as a source of parametric values The National Map as a source of parametric values Agricultural Non-Point Source (AGNPS) Pollution Model as a test case Agricultural Non-Point Source (AGNPS) Pollution Model as a test case AGNPS Data Generator (ADGen) AGNPS Data Generator (ADGen)

5. The National Map A synthesis of data, tools, and applications A synthesis of data, tools, and applications Seamless, continuously maintained, nationally consistent base geographic data Seamless, continuously maintained, nationally consistent base geographic data Partnerships Partnerships 24/7 on the Web 24/7 on the Web Source for products Source for products The United States’ geographic information infrastructure The United States’ geographic information infrastructure

6. The National Map: Data Content Orthorectified imageryOrthorectified imagery Land characterizationLand characterization ElevationElevation Vector layers:Vector layers:  Transportation  Hydrography  Structures  Boundaries Geographic namesGeographic names

7. The National Map System Architecture

8. The National Map Catalog There is only one The National Map Catalog There is only one The National Map Catalog It represents the set of all Web services that are being evaluated or have been approved as part of The National Map It represents the set of all Web services that are being evaluated or have been approved as part of The National Map There are many applications, partners, service providers, standards, teams, and business processes interacting with the one The National Map Catalog There are many applications, partners, service providers, standards, teams, and business processes interacting with the one The National Map Catalog

9. Viewer Application USGS Web Map Service Partner WMS 1 Partner WMS 2 Partner WMS n Product Generation Application Every application uses the Catalog to select the appropriate Web Services Data comes from Partner provided Web Services Partner Application The National Map CATALOG

10. The National Map Viewer The Viewer is the first application to use the catalog service The Viewer is the first application to use the catalog servicehttp://nmviewogc.cr.usgs.gov The Viewer has some very advanced behavior because of the logic implemented in the Catalog The Viewer has some very advanced behavior because of the logic implemented in the Catalog Any catalog-based application could take advantage of this advanced behavior Any catalog-based application could take advantage of this advanced behavior

11. The National Map as a source of parametric values National Elevation Dataset (NED) National Elevation Dataset (NED) And derived parameters: slope, aspect, landforms, etc. And derived parameters: slope, aspect, landforms, etc. For Natural Process Models For Natural Process Models Surface Runoff, Wildfires, Erosion, Sediment Transport, etc. Surface Runoff, Wildfires, Erosion, Sediment Transport, etc.

12. AGNPS Pollution Model as a test case Runoff, Erosion, Nutrient Transport Runoff, Erosion, Nutrient Transport Focused on Agricultural Watersheds Focused on Agricultural Watersheds

14. ADGen An ERDAS Imagine GIS -– AGNPS Interface An ERDAS Imagine GIS -– AGNPS Interface Elevation, Land Cover, and Soils as sources Elevation, Land Cover, and Soils as sources Derive the necessary 22 input parameters to the model Derive the necessary 22 input parameters to the model

21. Proof-of-Concept Web Modeling Application or Controller App Uses The National Map Viewer Uses The National Map Viewer User defined Area of Interest User defined Area of Interest Query, Download, and Pass to ADGen Query, Download, and Pass to ADGen AGNPS -> Model Output AGNPS -> Model Output Controller App (controlAp) Controller App (controlAp) orchestrate, monitor, and report orchestrate, monitor, and report

22. controlAp initially emulated or “hard-coded” User Define AOI Query Download ADGEN AGNPS output

23. controlAp Next Step User Define AOI Query Download ANY Environmental Model API or “Environmental Model” Web Service

24. Conclusions The National Map is ideally suited to act as an agent for web-based environmental models The National Map is ideally suited to act as an agent for web-based environmental models The National Map will be the US’ geographic information infrastructure The National Map will be the US’ geographic information infrastructure While the Viewer is the primary user interface for The National Map, the Catalog is the critical infrastructure behind the scene While the Viewer is the primary user interface for The National Map, the Catalog is the critical infrastructure behind the scene AGNPS as a test case AGNPS as a test case ADGen, the Imagine GIS Interface ADGen, the Imagine GIS Interface controlAP design demonstrates web modeling application or “modeling” web service concept controlAP design demonstrates web modeling application or “modeling” web service concept
