Summary of GIS Data on the Web

[Alicia Abramson]

I received a number of replies to my request for Web sites that provide
access to Geographic Information Systems data sets.  Thanks to all of you
who replied, you've provided me with a wealth of information!

Ive listed the sites below with either the original senders' or [my]
annotations:

*******************
The New York State GIS Clearinghouse

Focuses on NYS data, but on our Related Sites page there are links to other
states' GIS web sites, federal sites (e.g. sources for census data), and
links to several GIS directory sites, including one sponsored by ESRI
(maker of ArcView).  See:

National Oceanic and Atmospheric Administration

http://www.ncdc.noaa.gov/ol/about/ncdcnoaa.html

Within the U.S. Department of Commerce is the National Oceanic and
Atmospheric Administration (NOAA). NOAA conducts research and gathers data
about the oceans, atmosphere, space, and sun, and applies this knowledge to
products and services that benefit Americans. The National Climatic Data
Center is one of three National Data Centers under the National
Environmental Satellite, Data,
and Information Service (NESDIS), one of the NOAA Line Offices. NCDC is the
world's largest active archive of weather data. NCDC produces numerous
climate publications and responds to data requests from all over the world.
NCDC operates the World Data
Center-A, Meteorology which is collocated at NCDC. NCDC's web site has
received a number of awards. NCDC supports a three tier national climate
services support program - the partners include: NCDC, Regional Climate
Centers (RCC's), and State Climatologists.
