Global Change Master Directory
The USGS site for browsing and ordering satellite images, aerial photographs, and cartographic products. Replaced the Global Land Information System.
The 1:100,000-scale Digital Line Graph (DLG) data files are digital representations of
cartographic information. Data files of topographic and planimetric map features are derived
from cartographic source materials using manual and automated digitizing methods.
DLG files are distributed in three ways: over an anonymous ftp account (hydrography and
transportation only), on CD-ROM, and on magnetic tape.
Three-dimensional images and animations generated from high-resolution (30-m) data acquired during the February 2000 Shuttle Radar Topography Mission (SRTM). The site will ultimately contain topographic data of the entire world.
From a JPL site (http://www.jpl.nasa.gov/srtm/pub_dist.htm): "SRTM data for a number of sites within the United States are now available for download via File Transfer Protocol (ftp). Users should be aware that these data are intended for use with Geographic Information System (GIS) or other special application software, and are not directly viewable in a browser. Various types of visualizations (perpectives, stereo pairs, anaglyphs, etc.) generated using these data are available from the main page. Also, users should be aware that the digital elevation maps and images are unedited and are intended for scientific use and evaluation. They are outputs directly from the SRTM interferometric radar processor, and for example may contain numerous voids (areas without data), water bodies may not appear flat, and coastlines may be ill-defined."
The Land Use and Land Cover (LULC) data files describe the vegetation, water, natural
surface, and cultural features on the land surface. The U.S. Geological Survey
(USGS) provides these datasets and associated maps as a part of its National Mapping
Program. The LULC mapping program is designed so that standard topographic maps of a
scale of 1:250,000 can be used for compilation and organization of the land use and land
cover data. In some cases, such as Hawai'i, 1:100,000-scale maps are also used.
The LULC data are available (at no cost) through an Internet anonymous ftp account at the
EDC. The data are also available (at cost of reproduction) on magnetic tape from the USGS's
Earth Science Information Centers.
A Digital Elevation Model (DEM) consists of a sampled array of elevations for ground
positions that are normally at regularly spaced intervals. The 1-degree DEM (3-by-3
arc-second data spacing) provides coverage in 1-by-1 degree blocks for all of the
contiguous U.S., Hawai'i, and limited portions of Alaska. The basic elevation model
is produced by or for the Defense Mapping Agency (DMA), but is distributed by the USGS's
EROS Data Center in the DEM data record format. In reformatting the product, the USGS
does not change the basic elevation information. The 1-degree DEMs are also referred to as "3-arc
second" or "1:250,000-scale" DEM data.
A Digital Elevation Model (DEM) consists of a sampled array of elevations for ground
positions that are normally at regularly spaced intervals. The Digital Chart of the World
(DCW) DEM data provide 30-by-30 arc-second digital elevation data produced from the
Defense Mapping Agency's (DMA) 1:1,000,000-scale DCW contour and hydrology data.
Data for the areas listed below are currently available over an anonymous ftp account. If you
use this option, make sure to review the README file before downloading files.

Demographic information is usually provided on a national basis, even though countries
are always changing. As an alternate scheme, one might use ecological zones rather than
nation states. There is, however, no agreement as to what these zones should be. By way of contrast,
global environmental studies using satellites as collection devices yield results indexed by
latitude and longitude. Thus, it makes sense to assemble the terrestrial arrangement of people
in a compatible manner. This alternative is explored here, using latitude/longitude
quadrilaterals as bins for population information. This data format also has considerable
advantage for analytical studies.
There are four files in this dataset. Each file contains one variable. The variables are:
-
population counts, unsmoothed
file name gpxxx or countrawxxx
-
population density, unsmoothed
file name gppdxxx or densrawxxx
-
global population (counts, smoothed)
file name gppycxxx or countsmooxxx
-
global population (population density, smoothed)
file name gppycpdxxx or denssmooxxx
For most countries, data were available from the 1980s or early 1990s.
The data are available as ASCII files or as pkzip compressed ArcInfo
Export files. The ArcInfo Export files are in three formats:
-
ArcInfo GRID, 0.083 x 0.083-degree cell size (GRIDDD)
-
ArcInfo GRID, 5 x 5-minute cell size (GRIDDM)
-
ArcInfo polygon format, created from GRIDDM (POLYDM)

The purpose of this dataset is to provide paleoclimate researchers with a tool for estimating
the average seasonal variation in sea-surface temperature (SST) throughout the modern world
ocean and for estimating the modern monthly and weekly sea-surface temperature at any
given oceanic location. It is expected that these data will be compared with temperature
estimates derived from geological proxy measures such as faunal census analyses and
stable isotopic analyses. The results can then be used to constrain general circulation models
of climate change.
The data contained in this dataset are derived from the NOAA Advanced Very High
Resolution Radiometer Multichannel Sea Surface Temperature data (AVHRR MCSST), which
are obtainable from the Distributed Active Archive Center at the Jet Propulsion Laboratory
(JPL) in Pasadena, CA. The JPL tapes contain weekly images of SST from October 1981
through December 1990 in nine regions of the world ocean: North Atlantic, Eastern North
Atlantic, South Atlantic, Agulhas, Indian, Southeast Pacific, Southwest Pacific, Northeast
Pacific, and Northwest Pacific.
Several geographic datasets are available for use with ArcView, ArcCAD,
PC ARC/INFO, and ARC/INFO.

cities, and a latitude/longitude background)

Global ocean temperature and salinity measurements are regularly being taken by shipboard
observers or automated instruments. The data are then forwarded through radio or satellite
transmitters to receiving stations and transmitted in "real time" to operational users around the
world. The datasets listed below contain real-time data from the GTSPP database for the time
periods indicated. The data are arranged in quarterly segments. To view a data file summary,
select the quarter containing the dates of your choice and click on that selection. To view a
station location plot, select and click the corresponding X. To download a data file, select the
dates of your choice and click that selection. The size of each file is shown in megabytes.
Only one quarterly segment may be downloaded at a time.
GTSPP data are distributed in MEDS ASCII file format. A description of the file format and
code tables is available for viewing or downloading.
The different types of data found in the NDBC on-line archive are listed
below. A description of the data types and the units of each measurement is also
provided. You may wish to check the latest data availability summary to find the
dates for which data were collected at each station. The data files on this server
have been compressed using the GNU gzip utility.
Access to the data from each individual station is available through the NDBC
