Geoportal Server: Open Source Software for Data Discovery and More [1]
Submitted by superadmin on Wed, 2012-02-01 09:07The goal of this session is to introduce Geoportal Server as one of the data discovery and access services from different communities among NODC, NGDC, and EPA.
-
ESRI GIS portal toolkit -> Geoportal Server ( Christine White (ESRI) [6])
- Highly configurable
- Built on existing OSS platforms
- Active development
-
NODC use of Geoportal for Integration/Interoperation, John Relph, NODC [7], Ken Casey, NODC [8], Li, Jeff (NODC) [9]
-
Archival work - human and machine interfaces
- Target access to archives through various software services
- Need for service integration and organization
- Geoportal fills this need
-
Machine-to-machine communication via REST URL
-
Applications can construct individual URLs to pull targeted data
- Metadata selections, but custom coding often needed for unique datasets
- This lends itself to an agile archive which can conform to many different data/metadata requests
-
Dynamic, metadata created Web Accessible Folders (WAFs)
- Brief Access Records merged with FGDC XML generates live archive WAF
-
Applications can construct individual URLs to pull targeted data
-
Archival work - human and machine interfaces
-
NODC Collections WAF
- Collection level records, with HTML for Google harvesting
-
Data.gov/Geospatial One-Stop WAFs
- Immediately downloadable WAF only
-
NODC Geoportal Server Usability Test for first-time users
- Most use was scientific research
- Many different countries
- Spatial search had highest difficulty, free text and web interface tasks were also problematic
- Indicated that the map locator needs work, as well as text search, default syntax, and ontology services were needed
- Additional data visualization needed
- Move for Geoportal to use ISO19115-2 metadata
-
NGDC use of Geoportal David Neufeld (NGDC) [10]
-
Mixed content, WAF centric
-
Common Property Meanings to create shared concepts
- Simplifies search modifications, custom links to data
-
Common Property Meanings to create shared concepts
-
Improving metadata content
- Must work with data providers
- Metadata report card, based on metadata conventions
- Federated searches
-
Mixed content, WAF centric
-
Collaborations
- Information sharing
- GEO-IDE Wiki [11]
- Locator services
- Google code shared repository possible
-
EPA use of Geoportal David Parrish (EPA) [12]
- Environmental Dataset Gatewaty (EDG) [13]
- v 1.0 of Geoportal customized for EPA needs
- Public demand drives division of Air, Water, Waste categories
- Selection of data by region, type, owner
- Code for searches available to be imbedded in third party webpages
- Separation between public and private datasets
- Automation of data.gov records/inventory/formatting
- Metrics for data requests, world map of requests by country, metadata
- Clip N Ship
- Enhanced metrics, web services, web services and metadata
- Outreach and sharing of tech
