WATERS Web Services
• Public facing Web services for creating and applying NHD events and NHDPlus, including mapping services
– Enhanced from DB and SOAP to HTTP/REST – Code playground and javascript library– Transparency and efficiency for developers
• Visit www.epa.gov/waters/tools
• Performance concerns with EPA IT infrastructure!
• Access to framework geospatial datasets stored in the WATERS Database and to general purpose interactive service panels.
• Dialog boxes providing access to tools, services, and information, such as NHD feature name query, total waters, up/downstream navigation, watershed reports, ATTAINS reports, etc.
• Access to indexed water program features, with hyperlinks to additional attributes, and context sensitive analysis services, such as up/downstream navigation and watershed reports.

Geo Web Services Need to Perform
• Performance issues for large data volumes
• Boosting performance– Database tuning– Pre-computed network navigation attributes– Pre-computed results geometries– Cloud computing– Others?
