  1. The National Map Viewer

  2. The National Map Viewer is part of The National Map System

  3. However: The National Map is NOT the Viewer

  4. The National Map is a Relational Database

  6. Why A Relational Database?

  7. Internet Generic View of a Web Mapping Service Client

  8. Internet Generic View of a Web Mapping Service Query a Service using URL Syntax Client Service WMS

  9. Internet Source of Data Generic View of a Web Mapping Service Service Queries for GIS Data Client Service WMS

  10. Internet Source of Data Generic View of a Web Mapping Service Client Service WMS Response is Typically HTML or XML, but can be Text, Raster Images or other Formats

  11. Simple to Complex WMS Relationships

  28. State of Indiana Jill Saligoe-Simmel, Ph.D. Indiana Geographic Information Council, Inc. 317-234-2924 jsaligoe@iupu.edu www.in.gov/ingisi Who’s Who in The National MapPartner Registration Process US Geological Survey Charley Hickman, USGS Liaison to IN, MI, OH USGS Eastern Region Geog 614-430-7768 chickman@usgs.gov www.usgs.gov/ngpo

  29. State of Indiana Jill Saligoe-Simmel, Ph.D. Partner Registration Process US Geological Survey Charley Hickman, USGS Potential Partners? Indiana State Agency Local Government Academic Institution Regional Consortium Private Concern ER Catalog Support Team Reston, VA - Art Eckerson CR Catalog Support Team Rolla, MO – Larry Moore POCs

  30. Catalog Support Team Member Contacts Partner POC and Initiates Information Gathering: Data Types FGDC Metadata? WMS? OGC Compliant? URLs for: All WMSs Metadata Legends Public/Non-Public Layers Min/Max Scale for each Layer Data Layer Footprints Partner Information Page URL This is an Iterative Process

  31. Catalog Support Team Verifies all URLs Determines Classification of Data Layers to: TNM Themes ‘Other’ Categories Reviews Layer Scale and Symbology Reviews Place Names and Initiates GNIS Internal USGS Names Extraction Processes Reviews Metadata These Actions also Require Iteration with the Partner

  32. Catalog Support Team Initiates TNM Catalog Data Entry Process:

  33. Sample Oracle Screen from TNM Catalog

  34. Catalog Support Team Initiates TNM Catalog Data Entry Process: Establishes a Partner ID Number with CST in Rolla, MO Registers each WMS and Classify each Layer of the Service Tests in TNM (LIVE) Again, the Catalog Support Team Iterates with the Partner to Properly Register Partner Data in TNM Catalog

  35. Partner Assistance: Lacking FGDC Compliant Metadata? Catalog Support Teams (and Others) can Offer Assistance in Metadata Training, Some Metadata Content Entry (Caveat!! Contingent on Availability of Resources) No WMS? If Partner Plans to Move Toward a Local WMS Capability, Temporary Hosting and Serving of Data may be Possible via Indiana Map and/or USGS (More Caveats!!)

  36. Review > The National Map Catalog A Scalable, Relational Database that SimplifiesWMS Data Management Functions, and is Capable ofProviding Base Layer GIS Data to Multiple Applications

  38. Review > Who’s Who

  40. The Local Government Perspective Shaun Scholer, Wayne County GIS

  41. What's in it for YOU! • Integrate map data • Federal • State • Neighboring local government • Desktop applications running WMS plug-in • No more coping data • Broaden your user base

  42. What’s Required? • Web Service • ArcIMS - ESRI • MapGuide - Autodesk • WebMap – Intergraph • MapServer – open source • WMS service • Customize map • Metadata
