An Annotated Guide to Earth Remote Sensing Data and Information
Resources for Social Science Applications
Selected Remote Sensing Data Catalogs and Search Tools
Suggested starting points for general readers are indicated with an
3.1 Multiple Data Center Catalogs and Search Tools
- * SEDAC Data and Information Catalog Services. This online
search interface, developed by the Consortium for International Earth
Science Information Network (CIESIN), provides integrated searching
of multiple catalogs that conform to the Z39.50 international standard,
including the Global Change Master Directory (GCMD), various National
Oceanic and Atmospheric Administration (NOAA) catalogs, and CIESIN's
own metadata holdings. SEDAC Catalog Services support both full-text
search and Boolean searches on specified fields. Availability: http://wwwgateway.ciesin.org
- Department of Defense Master Environmental Library (MEL).
MEL is designed to provide a single point for searching U.S. Department
of Defense environmental data. It provides access to metadata developed
by distributed regional sites. Users may specify a location, time
period, keyword(s), and database of interest. Both Java and non-Java
query interfaces are currently provided. Availability: http://www-mel.nrlmry.navy.mil/homepage.html
- * Earth Pages. Earth Pages is an on-line search and index
tool for earth science data, information, and resources on the Internet.
Resources are organized by topic or alphabetically or may be searched
using keywords. Organizations must register in order to be included
in the database. Availability: (**not there)
- EOSDIS Information Management System (IMS). The IMS provides
access to the extensive data holdings of the Earth Observing System
Data and Information System (EOSDIS) of the U.S. National Aeronautics
and Space Administration (NASA). A X Window-based graphical user interface
(GUI) supports data searching and browsing, access to directory and
guide information, and data ordering. A WWW-based interface provides
more limited search and access capabilities. Availability: For the
WWW interface, see http://harp.gsfc.nasa.gov/~imswww/pub/imswelcome/
. For the GUI, see http://www-v0ims.gsfc.nasa.gov/v0ims/ims_access.html
for a list of telnet access points.
- European Wide Service Exchange (EWSE). The EWSE is an on-line
information exchange testbed of the Centre for Earth Observation (CEO)
Programme designed to help the Earth observation community find relevant
data and resources. The service supports both free text searching,
geographic and keyword searching, and browsing of a dynamic data base.
EWSE also provides access to gateways compatible with the NASA Information
Management System. Availability: (**not there)
- * The Global Change Master Directory (GCMD). The GCMD provides
access to an extensive set of metadata records describing remote sensing,
in situ, and other Earth science data. The GCMD search interface permits
both free-text and controlled searches (using standard search terms).
The GCMD is the American Coordinating Node of the Committee on Earth
Observation Satellites International Directory Network (CEOS IDN).
- Global Environmental Information Locator Service (GELOS).
GELOS is an alpha version search tool developed as part of the G7
Environment and Natural Resources Management project (G7-ENRM). The
G7-ENRM project seeks to create a globally distributed virtual library
of environmental and natural resource data. The current version of
GELOS supports free-text, geographical, and keyword searches. Availability:
- NOAA Environmental Services Data Directory. This catalog
includes metadata for the extensive environmental data holdings of
the U.S. National Oceanic and Atmospheric Administration (NOAA), including
many NOAA data centers such as the Satellite Active Archive (SAA),
the National Climatic Data Center (NCDC), the National Geophysical
Data Center (NGDC), and the National Oceanographic Data Center (NODC).
The catalog supports both full text search and custom searches utilizing
fields corresponding to the Governmental Information Locator System
(GILS) or the Federal Geographic Data Committee (FGDC) Content Standards
for Digital Geospatial Metadata. Availability: http://www.esdim.noaa.gov/NOAA-Catalog/
3.2 Selected Data Center Catalogs and Search Tools
- CCRS Earth Observation Catalogue (CEOCat). The Canada Centre
for Remote Sensing maintains an on-line inventory of "quick look"
images for its holdings of Land Remote-Sensing Satellite (Landsat),
Advanced Very High Resolution Radiometer (AVHRR), SPOT, and synthetic
aperture radar (SAR) data. Availability: http://www.ccrs.nrcan.gc.ca/ccrs/
- CRISP Catalogue Browse. Permits browsing of SPOT, ERS, and
RADARSAT imagery for South and Southeast Asia available from the Center
for Remote Imaging, Sensing and Processing (CRISP), the National University
of Singapore. Availability: http://www.crisp.nus.sg/
- EUS/Guide: EOIS User Interface Software for Guidesystem.
This prototype interface provides inventory-level search for the holdings
of the Earth Observation Information System (EOIS) of the National
Space Development Agency of Japan (NASDA). Searches may be conducted
based on dataset name, physical parameter, and sensor name for the
Japan area or the globe. Both English and Japanese versions of the
interface are available. Availability: http://www.eoc.nasda.go.jp/guide/eus/index.html
- Global Land Information System (GLIS). The U.S. Geological
Survey's GLIS provides on-line access to the extensive libraries of
land-oriented remote sensing imagery held by the U.S. government and
Canadian and European sources. Four different interfaces are supported:
a X-Window client, a PC client, an ASCII text interface, and a WWW
interface (including both "frames" and "nonframes"
versions). The client interfaces support more interactive and powerful
search and browse functions. Availability: http://edcwww.cr.usgs.gov/glis/glis.html
for WWW access and for information on downloading clients.
