CATALOGUE OF DIGITAL ELEVATION DATA LAST UPDATED: 23-JAN-1997
===================================

(c) Bruce M. Gittings, 1996.

This catalogue is available from the following sources:

- Posting on GIS-L / comp.infosystems.gis at the start of each month
- Through the World-Wide Web at URL http://www.geo.ed.ac.uk/home/ded.html
- By sending email to geo...@geo.ed.ac.uk containing the command
"SEND DEM"

This catalogue was compiled using my own information and the contributions of a
large number of helpful readers of GIS-L. It includes details of elevation and
bathymetric data, together with a section on available software for the display
and manipulation of these data. I would be very grateful for any corrections or
additions, which you can be assured will be of benefit to the whole community.

I am most grateful to the many individuals who have contributed. I have not
acknowledged individual names because some have specifically wished to maintain
their anonimity. If you supply me with material which, for one reason or
another, should have a name attached I am happy to do this. I must, however,
acknowledge the enormous help of Ernie Beale (e...@idirect.com) who has
put a lot of work into extending the catalogue, while undertaking the Master's
programme in GIS at the University of Edinburgh.

Some additional information (e.g. electronic documents which were the source of
some of the information included here) are available by e-mailing our automatic
information server (geo...@geo.ed.ac.uk).

PLEASE read the COPYRIGHT NOTICE and DISCLAIMER at the end of this message (if
either of these are missing, then this posting is incomplete).

NOTES
=====

(1) The Digital Chart of the World (DCW) was digitised under contract from US
Defense Mapping Agency (DMA) from their Operational Navigation Chart
(ONC) series. These maps are at a scale of 1:1M (except over Antarctica
where the scale is reduced to 1:2M). This is the largest scale
unclassified map series that provides consistent, continuous global
coverage of essential basemap features. It is composed of 17 thematic
vector layers which include political boundaries, coastlines, cities,
transportation networks, hydrography, landcover, hypsography and place
names. DCW can be purchased from:

UK/Europe: Chadwyck-Healey Ltd. Tel: (0223) 311479

US: USGS Open-File Section Tel: (303) 236-7476

DCW is distributed on FOUR CDs, with PC software to read the Vector
Product Format (VPF). The size of the whole DCW database is approx.
1.6GB. The size of the hypsography is estimated at ~450MB. There is
also some supplementary hypsography which is estimated at ~150MB. The
individual 5 x 5 degree tiles vary greatly in terms of their data volume.
The absolute accuracy of the DCW vector information is 2000m circular
error (horizontal) and +/- 650m linear error (vertical) for the contours.
The vertical accuracy for the spot heights is +/- 30m. All are at 90-
percent confidence as defined by the US Defense Mapping Agency (DMA).
