USGIN Metadata Wizard released

Submitted by admin on Mon, 07/19/2010 - 11:42am

The USGIN Metadata Wizard is a metadata-format agnostic metadata creation web-tool that exports its generic, minimum metadata model into various metadata formats and standards such FGDC XML, and ISO 19139 XML files. The goal of the tool is to make new metadata creation as simple as possible while still supporting several metadata standards. Give it a try at http://mw.usgin.org

USGIN Catalog and Data Services website released

Submitted by wgrunberg on Thu, 04/15/2010 - 2:40pm

The USGIN Catalog and Data Services website (http://catalog.usgin.org) hosts several geospatial metadata catalog (CSW) and geospatial data services (WMS, WFS, WCS) implementations and clients. Although the site functions as a showcase of USGIN service implementations, the Catalog Service for the Web service (CSW - http://catalog.usgin.org/geonetwork/srv/en/csw) is a primary metadata node for the U.S. Geospatial Information Network.

Available services and clients at this time:

USGIN Document Repository released

Submitted by wgrunberg on Thu, 04/15/2010 - 11:23am

The USGIN Document Repository is an effort to create a document archiving, management, and discovery system that fulfills minimum USGIN ISO 19139 metadata requirements. The Drupal CMS based site is under active development and has the following goals and requirements:

  • Upload files that have not been put on the web yet and generate metadata for them
  • Add links to resources that are already on the web and generate metadata for them
  • Automatically generate ISO 19139 dataset metadata XML records
  • Offer an as easy-as-possible way to enter minimum ISO 19139 metadata
  • Use Search Engine Optimization to expose content to the web
  • Offer some nice way to search the repository
  • Offer a minimal but intuitive workflow for repository management
  • Find an easy way of submitting spatial extent coordinates
  • Remain flexible to adapt to new and changing metadata input and presentation needs

USGIN ISO 19139 Profile

Summary:

USGIN profile for using ISO19139 xml schema for ISO 19115 and ISO 19119 spatial metadata. ISO 19115 is a metadata standard for spatial dataset and spatial dataset series. ISO 19119 is a metadata standard for spatial services. The USGIN profile for ISO 19139 is based on the North American Profile (NAP).

Introduction:

A key component of a distributed information network is a catalog system, a collection of resources that allow data and service providers to register resources, and data consumers to locate and use those resources. Currently, many online catalogs are web pages with collections of URLs for services, or services are discovered accidently or by word of mouth. The vision is to enable a web client (portal) to search across one or more metadata registries without having to configure the client individually for each of the registries that will be searched. Thus, metadata providers can focus on data development, without having to also develop web clients to enable search of that metadata.

AASG NSF Interoperability Project

Type: 
Project

One of the major projects currently developing US Geoscience Information Network capabilities is named the Geoscience Information Network (NSF GIN).  This project provides funding to assemble key modules and adopt standards and protocols to build an interoperable national Geoscience Information Network (“GIN”) that already has strong community engagement and broad consensus. The GIN is being developed in the context of national and international communities for enhanced global geospatial data interoperability. In an NSF-sponsored workshop, the nation's geological surveys agreed to the development of a na-tional Geoscience Information Network (GIN) that is distributed, interoperable, uses open source standards and common protocols, respects and acknowledges data ownership, fosters communi-ties of practice to grow, and facilitates development of new web services and clients. Geological surveys have an estimated 2,000 – 3,000 databases that represent one of the largest, long-term information resources on the geology of the United States and collectively constitute a national geoscience data “backbone” for research and applications.

GeoSciML WFS architecture

Interoperable OGC Web Feature Services based on the GeoSciML Schema require specification of numerous aspects of the network architecture to enable clients to interact successfully with any profile-based server.

A 'global' GeoSciML WFS architecture profile will be inherited as the framework for more specific GeoSciML feature services like Fault, GeolgoicUnit, MappedFeature, GeologicMap package, and others that may be developed.  This profile is thus viewed as a parent profile to these other more specific profiles.
