The higher the Check with the NTIS (national Technical Information Service), they have a copy of the CIA world map database available for a low copying fee. It is a very involved database containing data in radians to 4 decimal places...it's big but can be reduced. The last version of the database I heard of had 4 files. The world in great detail, the world with less detail showing country boundarys The US showing major lakes and rivers and the US showing county boundaries. There are other more detailed maps of the US available from the US Geological Survey Department USGS ...these contain topographic information, water resources ...etc depending on which ones you get.

You might try the National Center For Atmospheric Research (NCAR)
in (Boulder|Colorado Springs) CO
or
The Defense Mapping Agency (Washington, DC??)
They both keep databases and are government agencies (freedom of
information act and all that)

There's a set of disks available from PC-SIG in Sunnyvale CA that has the world map database on it. Their phone number and address have been posted to the net several times before; I don't have them with me now. -Ed -- Ed Post -- hplabs!lewey!evp (408)252-8713 American Information Technology; Cupertino, CA 95014

I have tried using the world database to which several contributors have
referred -- it is too large for some applications. I wanted to prepare
a map of Eastern Canada to 0.1 degree resolution, and I ended up with
an incredible complex of many tens of thousands of points. It really
takes a mainframe to do anything useful with this. Does anyone know of
a low-resolution data base?
Also, does anyone know a data base with bathymetric data for Eastern
Canada, such as 100, 200 and 1000 m countours?
