## The Earth Systems Information Partnership (ESIP)

- The Federation of Earth Science Information Partners is a network of researchers and associated groups that collects, interprets and develops applications for satellite-generated Earth observation information. Founded in 1998 under a grant from NASA, the consortium includes more than 80 member organizations, spanning NASA and NOAA's data centers, government research laboratories, research universities, education resource providers, technology developers, and nonprofit and commercial enterprises.

## What is a Metadata Portal?

- Repository of _standards compliant metadata_ (FGDC, ISO) integrated into a discovery system, which provides metadata search and browse capabilities, a map viewing capability, and efficient linkages (2 clicks to content) to external content.

- _What is a Metadata Portal?_

## What is the ESIP Portal - “Earth Information Exchange?”

- A Metadata Portal which will provide a gateway for viewing, exploring and accessing earth science data, applications, and supporting documentation provided by the 80 plus ESIP member organizations.

- _What is the ESIP Portal - “Earth Information Exchange?”_

## What makes the Earth Information Exchange Unique?

-  An Earth Science data portal
-  Organized, maintained and administered by scientists
-  Efficient, standardized access to the comprehensive data resources of all ESIP partners (currently 80 and growing)
-  Access to a wide array of earth science content (web applications, reports, services, models, etc.)

- _What makes the Earth Information Exchange Unique?_

## What makes the Earth Information Exchange Unique? (cont)

-  Robust data search and discovery tools appropriate to earth science community
-  Custom, Science-focused visualization and analysis tools
-  Science data interoperability tools
-  Integration of FGDC Remote Sensing Extensions
-  An marketplace to foster the exchange of ideas, data, and information with the science community.

## ESIP & Geospatial One-Stop (GOS)

- What is GOS?
* **GOS is a geographic information system (GIS) portal known as the Geospatial One-Stop (GOS), that serves as a public gateway for improving access to geospatial information and data under the Geospatial One-Stop E-Government initiative.*
* **The GOS portal is a catalog of geospatial information containing thousands of metadata records (information about the data) and links to live maps, features, and catalog services, downloadable data sets, images, clearinghouses, map files, and more.*

- _ESIP & Geospatial One-Stop (GOS)_

## ESIP & Geospatial One-Stop (GOS)

- What similarities exist between (EIE) and GOS?
-  Both utilize the same portal technology (ESRI Portal Toolkit)
-  Both portals contain federal government metadata
-  Overlapping Agencies (NOAA, NASA & EPA)
-  Overlapping User Communities
-  Both portals require standards compliant metadata
-  FGDC
-  ISO
- Is there likely to be a future partnership between EIE & GOS?
-  YES

- _ESIP & Geospatial One-Stop (GOS)_

## Partnership Spectrum

- ESIP as a community within GOS
-  Unique Look & Feel
-  Developed and maintained by ESIP

**Notes:**
Community
     - ESIP has complete control of organization and structure of community
            -channels (GEOSS, NASA special interest areas)
     - utilizes GOS infrastructure 100% support resources

ESIP Portal
     - Creates & maintains its own portal
     - provides own infrastructure and support resources
    - utilizes portal toolkit 

## Benefits of ESIP becoming a GOS Community

-  Use new tools to build an Earth Science Community
-  Leverage GOS IT and Support Resources
-  Help partners comply with OMB E-Gov Initiative
-  Begin to establish a unified metadata repository and data explorer interface for the science community
-  Encourage inter-agency data sharing and collaboration

## NOAA and Geospatial One-Stop?

-  NOAA Metadata Challenges
- Standards Compliant Metadata
- Accurate Up-to-date Records
- Single Data Discovery Interface
-  NOAA Metadata Infrastructure
- NMMR / CoRIS

- _NOAA and Geospatial One-Stop?_

- Addressed by GOS?

**Notes:**
3 slides about NOAA Metadata

## Connecting NESDIS to Geospatial One-Stop

- Option 1: Geospatial One-Stop would be supported as an external interface through NOAAServer.

## Connecting NESDIS to Geospatial One-Stop

- Option 2: Geospatial One-Stop would be supported directly from the NOAA Metadata Manager and Repository for NESDIS metadata. Other Line Offices develop and maintain independent systems.

_**Other options...? **_

## Organizational Questions?

_**Organizational Questions?**_

-  Content vs Interfaces
-  Spend time building interface or focus on creating good metadata (content)
-  Google or Facets
-  speed and comprehensive nature of google
-  specific fielded searches of facets
-  Distributed vs Centralized Searches
-  AND instead of OR
-  Federation or Organization
-  carrot vs stick

**Notes:**
Fed or Org
Federation (collaborate with other organizations) ESIP (carrot driven)
Organization (Internal Approach) NOAA Server (stick driven)

Centralized or Dist
-Centralized – network of multiple catalogs
      -slower searching
      -performance determined by slowest site
      -no control over quality of metadata
-Distributed
      -Includes more organizations
      -Flexible
