Web Services USGS/EPA Collaboration

Transcription

1 Web Services USGS/EPA Collaboration June 11, 2008 Dwane Young, U.S. EPA; Jon Scott, USGS; Dorinda Gellenbeck,, USGS; Nate Booth, USGS NJ Water Monitoring Council Meeting 1

2 USGS NWIS* & STORET Over Time 1960s: NWPCA (WATSTORE) 1972 EPA created NWIS* Data copied from NWIS to STORET Legacy STORET 2003: USGS / EPA Agreement 2007: Water- Quality 1999: Modern STORET Data Exchange * USGS National Water Information System 2

3 Overview Working together to develop a common suite of web services Focus: sharing of water monitoring data via a common format and common terminology USEPA initial web services are now available USGS web services are in final testing for initial services 3

4 Relevance Efficiency - more with less New capabilities Data mining Reporting to other systems Support monitoring networks Shared applications OMB mandate Now... momentum towards a community of water-quality information 4

5 Why Now? Business: Water-quality data standards (NWQMC) Move towards monitoring network partnerships Technical: Industry move towards data and process sharing Technology standards 5

6 What is a Web Service? USGS Internet (XML) EPA Computer-to-computer Uses Input parameters and outputs XML Can be used in multiple ways by many applications 6

7 A common web service example Weather Network Weatherbug is an example that many are familiar with This is all done via a Web Service Returns XML Input Parameter: Zip Code Weatherbug translates XML into information for the task bar 7

8 An example using Monitoring Data 8

9 XML Google Earth (KML) 9

10 So What? Web Services allow for more accessibility to the data. No longer limited to EPA or USGS interfaces for interacting with the data. Web Services makes a STORET/NWIS collaboration possible. 10

11 So What? (cont d) Web services can: potentially serve as feeds for other state reporting or analysis databases provide a commonly formatted dataset for data analysis and modeling serve as the backbone for project data applications (mashups( mashups) 11

12 Water-Quality Web Services Initial Tasks Design a common data format based on USEPA WQX Map Parameter Codes to EPA s s Substance Registry System Translate other data elements: Site Type, Media and Chemical Groups Develop common services for serving Sites, Samples and Results 12

13 Data Translation PCODE SRS Name Units Fraction Temperature Basis Statistical Basis Time Basis Weight Basis Particle Size Substance Registry System 13

14 What Web Services are planned? Four core services are being developed: Stations service provides specific station information Results service provides results for modeling, analysis, and decision making Watershed/Station Catalog service provides summary information on what data are available Project Catalog service provides summary information by projects based on an input of min/max latitude/longitude 14

15 What s s Next Testing of services with both USEPA and USGS active Expect to release this year A common portal for interacting with these services Additional design for sediment and groundwater Inventory (Data Discovery) and summary services by: Site, Geographic Area, Watershed, Project 15

16 Future Dealing with duplicated data Common spatial framework: NHDPlus Web services support: software libraries and format translators Portal and analytical applications Definition and official approval of a Catalog/Inventory schema 16

17 Portals The Vision USGS Internet EPA EN Node Web Services Station Services Inventory Services Result Services Small Provider State 17

18 Take-home points WQX is the standard language for these services Two types of services available WQX EN Services (used primarily for data QA and visualization of submitted data, incorporating the EN security model). Water Quality Web Services (EPA/USGS Public services used for accessing the whole suite of water quality data available). Both types of services should be available via the Exchange Network Opportunity to define what a catalog/inventory schema would look like in order to build towards a future vision 18
