2010 WSWG Activities  Web service training  EGIS Brownbag Series Geospatial Web Services Web mapping applications for science  ITEM 2010 Data Integration Track  Web service landscape survey  FY 2010 Funding: 0.00$

ITEM Data Integration Track  Geospatial Web Services 101  Introducing Web Services for ArcGIS Desktop Users: David McCulloch  USGS Water Web Services: Present and Future: Mark D Hamill  Open-source technologies for geospatial web services: Peter N. Schweitzer  Web Mapping For Science  SPARROW DSS tool: Nate Booth  Using ArcGIS Server to Generate Tile Overlays for Google Maps API Web Mapping Applications: David MCCulloch  Geoscience web applications: Connecting services to interfaces effectively: Peter N. Schweitzer

Training Impressions  Tremendous interest  Standing room only: ITEM and Brownbags  Technical and collaborative  Excellent for community building  Disconnect between USGS IT and USGS ‘data’ people

Web Services Survey  Mid December-January  A Broad-brush overview  Not an inventory or registry  Goals  Foundation for “web services” community Identify good “stories”  Starting point for (potential) future inventory  May help guide best practices Develop web service rules Steer bureau-wide education and support “Voluntary survey to describe the landscape of web services within the USGS”

Implementation

Results  30 Respondents  131 web service “collections” totaling 600+ individual services  31 collections (90 services) not registered with data.gov, GOS, etc..  Types  Geospatial (544 out of 600 services) Geoprocessing (Elevation Slope Aspect)  Geocoders  A couple of “tabular” services

Platforms

Specs

Survey Shortfalls  Not an inventory  Not directly usable for discovery  Not comprehensive  Statistics may mislead us  What is a web service?  Websites, applications, etc…  Wikified results  Good for humans, not so much for automation  Manual maintenance required

Whats Next

Best Practices Information Sharing Collaboration Sharing Stories Who Inventories Standards WMS WFS ArcGIS (That’s a lot…how do we proceed?)

Collaboration/Sharing/Community  We want you!!! (broader involvement)  Story telling/sharing before each meeting  Peer support  Continue leveraging CDI Wiki  ArcGIS developers My USGS Community

 Continue Enterprise-GIS sponsored brown bags  Alphabet soup documentation Training and Education

Identify and Document Best Practices  Web services  How to setup services for… Mapping Applications Interoperability  OGC (WMS, WFS etc…) getCapabilities requirements  ArcGIS REST  Best practices for documenting (metadata) services  FGDC, Services Directory, getCapabilities  CDI metadata community

General Issues and Questions  Pragmatism/Realism  We have ‘day jobs’  (geospatial) blinders  Integrated discussions with other groups  Documenting web services = WSWG + MWG  Consider lessons learned/remaining questions from DI Development Project  WSWG Directions  Need the community (you) to help guide
