FEDEO

PURPOSE

FedEO (Federated Earth Observation missions access) provides a unique entry point to a growing number of scientific catalogues and services for, but not limited to, EO European and Canadian missions. FedEO is deployed with ESA (European Space Agency) infrastructure as a gateway to:

Provide brokered discovery, access and ordering capability to European/Canadian EO missions data based on HMA (Heterogeneous Missions Accessibility) interfaces;
Implement the OpenSearch OGC (Open Geospatial Consortium) and other interfaces for an increased number of discoverable and accessible EO data collections;
Implement the OpenSearch OGC interfaces for interfacing with CEOS Community Catalogues and Clients.

FedEO was initially developed as a prototype for GEO/GEOSS (Group on Earth Observations/Global Earth Observation System of Systems) and for EO-DAIL (Earth Observation Data Access & Integration Layer). It was consolidated after the CEOS Plenary in 2012 to facilitate access to European missions data in the international context and primarily in CEOS.

OBJECTIVES AND USE SCENARIOS

FedEO supports the following ESA EO Directorate Objectives:

Ensure timely and easy access to all EO data resources (current and historical) to the broad data user community;
Strengthen the ESA role in supporting national missions in both a European and global context;
Establish and reinforce strategic cooperation with international partners and strengthen ESA role in coordinating and representing MSs in the international fora;

Through providing a gateway:

to European EO data to facilitate discovery & access in the international context (e.g. GEO, CEOS) and the support to international initiatives and projects - (Scenario 1)
for European users and projects (e.g. TEPs) to European and non-European EO data - (Scenario 2)
facilitating ESA bilateral cooperation activities and data exchange (e.g. with NASA) – (Scenario 3)

Search Help

Non Advanced Search or Natural Search

The documents are returned sorted on relevance depending on order, proximity, frequency of terms.

Advanced Search or Boolean Search

Default search behavior

By default, all search terms are optional. It behaves like an OR logic. Objects that contain the more terms are rated higher in the results and will appear first in their type. For example, wiki forum will find:

objects that include both terms
objects that include the term wiki
objects that include the term forum

Requiring terms

Add a plus sign ( + ) before a term to indicate that the term must appear in results. Example: +wiki forum will find objects containing at least wiki. Objects with both terms and many occurences of the terms will appear first.

Excluding terms

Add a minus sign ( - ) before a term to indicate that the term must not appear in the results. To reduce a term's value without completely excluding it, use a tilde. Example: -wiki forum will find objects that do not contain wiki but contain forum

Grouping terms

Use parenthesis ( ) to group terms into subexpressions. Example: +wiki +(forum blog) will find objects that contain wiki and forum or that contain wiki and blog in any order.

Finding phrases

Use double quotes ( " " ) around a phrase to find terms in the exact order, exactly as typed. Example: "Alex Bell" will not find Bell Alex or Alex G. Bell.

Using wildcards

Add an asterisk ( * ) after a term to find objects that include the root word. For example, run* will find:

objects that include the term run
objects that include the term runner
objects that include the term running

Reducing a term's value

Add a tilde ( ~ ) before a term to reduce its value indicate to the ranking of the results. Objects that contain the term will appear lower than other objects (unlike the minus sign which will completely exclude a term). Example: +wiki ~forum will rate an object with only wiki higher that an object with wiki and forum.

Changing relevance value

Add a less than ( < ) or greater than ( > ) sign before a term to change the term's contribution to the overall relevance value assigned to a object. Example: +wiki +(>forum < blog) will find objects that contain wiki and forum or wiki and blog in any order. wiki forum will be rated higher.
