- NASA Informational Links
- Search
- Harvest
- Publish resources
- Visualizations
- Collaborative Individual Accounts
- FY05 & FY06 Advancements

## Purpose & Scope

**Purpose**
-  Extending accessibility to NASA’s extensive Earth Science information systems and research results through interoperability.
**Scope**
-  Gateway to NASA’s data products, model outputs and informational sites
-  Comprehensive registry of NASA’s Earth Science research results and components
-  Support NASA and its partner scientists, analysts, data managers, educators and decision makers
-  Resource to National and International societal benefit initiatives
-  Resource to NASA’s data products through interoperable web services

## Objectives

- Employ Services Oriented Architecture
- Build on Commercial Software
- Implement publicly accessible geospatial interoperability standards
- Extensibility & flexibility
- e.g. new web services, 3D viewers
- Access NASA’s science components
- e.g. satellite imagery, models, decision support systems, visualizations
- Link/register partner agency Decision Support Tools
- Create collaborative environment for users of NASA components
- Provide catalog search and data access functions to enhance Decision Support Systems

## ESG concept overview

**Earth System Gateway**
**Portal to ****data, ****information,****knowledge ****about the Earth-Sun System**

**Application Integration Framework**

- Extensible, open portal architecture

**Notes:**
OGC’s approach is based on interoperable web services, and emphasizes reusable applications service components. The diverse collections of geospatial data can be published, made accessible via the ESG portal, and usable by applications services to meet agency decision support needs.  

Rather than implementing a single solution that embeds a diverse array of functionality that cannot be easily interchanged, the OGC approach emphasizes “swappable” application, portrayal, processing, catalog and authentication services.  Please keep this in mind as you review the OGC ESG Portal demonstration – the ESG Gateway is a distributed, multi-vendor services based system

 This approach maximizes choice – Missions are able to procure or develop, and plug in standards-based application service components that have the functionality to best suit their mission needs.  Additionally, this approach encourages the reuse of services not only within agencies, but between agencies.

- ESG Data Concept

**Notes:**
Data management is a necessary first step in achieving the synergistic benefits from the U.S. Integrated Earth Observation System.

Expected outcome includes data management systems that are well-linked and support the full information cycle from observation acquisition to information delivery. 

At a minimum, the U.S. Integrated Earth Observation System must address these urgent needs by focusing on specific data management solutions:

Data and products will be made readily available and easily accessible by standardizing vocabularies across agencies and developing browsing and visualization systems. 

Interoperability is achieved through protocols and standards agreed upon by the member agencies. 

Metadata will be critical to the success of any integrated data management system. 

## Capabilities and Use

- NASA Informational Links
- Links to NASA web sites with mission, model, and science focus information and data products
- Search
- Distributed or local searches
- Harvest
- Harvest from catalogs, clearinghouses, etc. (GSDI, GCMD, ECHO)
- Publish resources
- Register metadata in ESG registry
- Visualizations
- Interactive viewer using publicly accessible standards (WMS)
- Retrieve layers from remote servers, display in single view
- 3D and 4D viewer capability
- Collaborative Individual Accounts
- Save map context files for future use, to share, to chain web services

## Earth Science Gateway (ESG)

## Searching ESG

- Provides an intuitive user interface

## ESG Viewer

- Multi-source client for Web Services

- Viewer controls: zoom in/out, load, save, identify, etc.

- Forward, Back, Search, etc.

## ESG Publish

## ESG Collaborative Individual Accounts

- Add users and groups, personalize with portlets**  **

- Collaborate with individuals or groups, share documents and context files.
