SE Coastal Network Water Quality Inventory & Monitoring Program Database Development Wade Sheldon & John Carpenter Dept. of Marine Sciences University of Georgia
2
Project Background NPS identified need to compile information on long-term monitoring of water quality in SE coastal waters In Fall 2007 we proposed to: Conduct workshop to gather input, info on regional activities Compile database of long-term monitoring program metadata Produce report summarizing monitoring in region Develop interactive web applications for querying database
3
Database Design Process - Research Reviewed other environmental monitoring database efforts International: GTOS TEMS (http://www.fao.org/gtos/tems/) Regional: Gulf of Maine Council on the Marine Environment (http://restoration.gulfofmaine.org/) OOS, regional consortia (SECOORA), … Reviewed monitoring program/observation metadata standards MMI (http://marinemetadata.org/) – various schemas, drafts EPA STORET (parameters) – legacy metadata NEIEN (EPA/States/Tribes) Environmental Data Standards Council (2006 standards/schemas) Water Quality Exchange (WQX) – STORET replacement NWQMC - Water Quality Data Elements
4
Database Design Process - Evaluation Concluded huge amount of work going on to standardize and coordinate metadata/data exchange Regional consortia, EON/IOOS New NSF programs (INTEROP, FEON) Differences in approaches, progress Detailed schemas & standards -> basic metadata content recommendations without implementation tools -> plans in development Some controlled vocabularies, but not widely applied Common threads Geospatial query/visualization (Google Maps API common) Thematic searches at varying granularity (topics, programs, parameter types)
5
Database Design Process - Approach Decide on initial scope NPS goal: Water Quality monitoring in SE coastal zone (NC,SC,GA,FL) Geographic bounds Initial monitoring programs to target Design, prototype relational database to support thematic and geospatial queries for targeted content Support relevant metadata content standards (EDSC, NWQMC) Flexibility for adding new metadata fields, varying completeness Support varying granularity in searches (broad-to-narrow), hierarchies
6
Geographic Scope: Defining the Coastal Zone
8
Initial Monitoring Programs USGS National Water Information System Large amount of relevant, long-term data (water quality, streamflow, groundwater) Excellent support for data mining (XML reports, RDB data) Use STORET parameter codes (basic groupings, units, methods) NOAA National Estuarine Research Reserve SWMP Relevant, medium-long-term data Support for mining stations, parameters via SOAP EPA STORET Problem: many sites without locations, complete metadata “In house” programs (GCE-LTER, NPS)
9
Prototype Relational Database Draft completed in May 2008, implemented in SQL Server 2000 Basic structure: Research Projects Monitoring Programs Monitoring Stations/Sites Parameters/Methods Scalable metadata model used for projects, monitoring programs Some fixed fields (title, desc., dates, web url) Additional editable lists of available fields with web display options Developed administrative forms (MS Access) Prototype web interfaces under development (demo’d here)
11
Administrative Forms – Metadata Fields
12
Administrative Forms – Projects
13
Web Forms Interface
14
Next Steps Gather workshop feedback on: Overall approach Metadata content to survey Queries, output formats to support Controlled vocabularies, hierarchies for parameters Complete web interfaces for interactive input, queries, map display Solicit metadata from other groups Continue to develop automated ingestion approaches XML/XSLT/SOAP Spreadsheet templates Prepare NPS report
15
Map Visualizations – Draft Google Earth Display
16
Spatial Query – Google Maps & Place Names
