WMT I Implications

• Increased capability, flexibility, choice of
  web-based tools
• Access and exploit a wide variety of geodata
  on-demand
• Access and maintain only the data you care about
• Increased government, business, and consumer use
  of spatial data and tools in decision-making
• Unique public/private partnerships and
  collaborative teaming
• Testbed approach accelerates the standards
  development process

3
Web-based Mapping Vision WMT I Goals
Web servers and map viewer clients interact to

• Discover, access and retrieve views from
  multiple servers

• Display multiple layers of geographic data
  within a single web application

• Query and update

• Provide interface for visualization, Decision
  Support, etc.

• Support geocoded raster, vector, matrix, and
  other data

4
WMT I Specifications for Open Web Mapping

• GetMap - Specifies communication protocols to
  merge many web map views into one view.
• GetCapabilities - Explains what a map server can
  do (so integrators know what to ask for).
• GetFeatureInfo - Specifies how to ask for more
  information about web map features.

General Focus for WMT II

• Expand web mapping services capability to meet a
  broader cross-section of community needs
• Get more federal data on-line using WMT protocols
• Implement Pilot Projects that put the WMT
  protocols in context in various US communities

6
Web Mapping Testbed Spiral II Specific Focus
Areas

• Finalize and publish the first three open
  technology protocols standards (March 2000)
• GetFeatureInfo
• GetMap
• GetCapabilities
• Legends and Symbology

7
Web Mapping Testbed Spiral II Specific Focus
Areas (contd)

• Getmap with vector packaging
• WMT I was largely a raster (e.g. GIF) format
  activity
• Need vector feature data to enable smart
  applications
• Tight integration with Catalog Services
• Increased emphasis to make federal agency servers
  available via WMT protocols
• WMT protocol Tool Kits
• How to implement protocols on map servers

8
Web Mapping Testbed Spiral II Specific Focus
Areas (contd)

• Update /Create capability
• Initial capability to update data stores behind
  map servers
• Coverage Data Access
• Extending vector feature data access capability
  to imagery and raster data
• Get information at a specific point in the image
  (i.e. average temperature at a specific location)

9
Web Mapping Testbed IISpecific Focus
Areas(contd)

• Pilot activities
• Deploy WMT I/II capabilities in programs of
  interest to sponsoring organizations
• Red River Basin (Corps)
• FGDC will seek proposals from 3-4 communities in
  the US via FGDC Cooperative Assistance Program -
  direct community involvement in WMT
• Other Sponsor Selected Project site(s)

10
FGDC Cooperative Assistance Programs

• The Cooperative Assistance Program has been used
  to encourage NSDI practices within US
  communities
• Tuned each year to
• emphasize different areas
• of NSDI (framework,
• Metadata, Clearinghouse)
• Seed funding only, intent
• is for communities to
• become self-sustaining
• 2000 program will include
• WMT II focus

11
WMT II Schedule
