The WATERS Web and Database services provide open interfaces to complex analyses. These services make extensive use of NHDPlus and referenced program data in the Reach Address Database, and also integrate other WATERS program data. Designed as loosely coupled modular units, the services are developed in a common architecture.
The WATERS Database Services require users to be on the EPA network and to have a TSMSS ID and schema password. Database Services provide users with the advantage of deploying applications within EPA that can take advantage of direct database call functionality.
|Service Name||HTTP Service||Database Service|
|Event Indexing Service
The Event Indexing Service allows users to dynamically index features against NHDPlus hydrology to create RAD-ready events.
|Point Indexing Service
Service providing point indexing via distance or NHDPlus flow direction raindrop indexing to NHDPlus features.
Advanced query function to find water feature names and provide general location information for NHDPlus features.
|Upstream/Downstream Search Service
The Upstream/Downstream Search service is designed to provide standard traversal and event discovery functions upon the NHDPlus stream network.
The Navigation service provides standard stream traversal on the NHDPlus stream network.
|Navigation Delineation Service
Service providing basin or other feature type delineation based upon navigation results.
|RAD Event Info Service
Service providing detailed information on Reach Address Database events.
Query services returning small non-spatial result sets of WATERS data.
|Results Queue Service
Service for managing asynchronous processing of other WATERS services.
|Spatial Assignment Service
Service providing spatial interaction information for a given geometry using various layers within WATERS.
WATERS mapping services provide access to feature layers via ESRI and Open Geospatial Consortium Exitservice formats. Users can consume WATERS datasets using client applications such as ArcGIS Desktop, Bing Maps, Google Maps, Leaflet, Google Earth and/or ArcGIS Explorer. Developers can utilize these services to incorporate WATERS feature layers into their own mapping applications. Specific information about the mapping services are documented on the WATERS Mapping Services web page.
WATERS provides an opt in/out mailing list which allows partners to stay informed about announcements related to WATERS. Announcements include but are not limited to new service offerings, changes to existing services, etc. If you would like to join the mailing list, please send an e-mail to firstname.lastname@example.org or use the Contact Us web page.
