The CD costs $375.00 and contains about 50 raster files, each of which covers
the entire world (scale varies among maps).  The data can be imported directly 
into GRASS, and the documentation provides intructions on importing the data 
into Idrisi.  The data are stored in flat, uncompressed format so that one can 
more easily import them into other GIS's as well.  

The data are provided under a license agreement, so one must purchase the
license in order to legally use the data.  The data are not, therefore, public
domain.  A few of the files can be retrieved by anonymous ftp from the GRASS
ftp site (moon.cecer.army.mil)--the Rutgers people worked together with
the CERL people to produce the CD, and CERL's contributions are public
domain.

Hope this helps,

Correct me if I'm wrong, but what all this digital scale stuff comes down to 
is the *resolution* of the data.  If the printing or digitising is only accurate or precise 
to (say) 0.5mm, then this will produce digital data of a resolution of 50m from a 1:100 000
original.  But much better to say that the data is "good to 50m" than it is 1:100 000 
in the digital realm?

The 1:2,000,000 DLG is available on CD ROM for $32.  There is no restriction
on the copying and use of the data.  The data on the format is present on
the CD/ROM (they also gave me a printed copy).

DEM's are available on tape, (again there is a USGS "User's Guide" describing)
the format, the pricing depends on what you order.  They do not have a CDRom
version yet (though there is some DEM data on the AVHRR companion disk).

Also recently available, is DMA's ONC charts repackaged in a 4 CDRom set called
"Digital Chart of The World."  The cost is $200, and program called VPFView
to look at the data is provided (C sources are included, it compiles with
Borland Turbo C).  The format is DMA's Vector Product Format which you can
order from the military (though USGS gives you the wrong spec number in their
brochure and you end up getting some wierd tank spec as a result).  USGS is
handling the sales through it.  There appears to be no copyright or other restriction mentioned.  All the disks say on them is "UNCLASSIFIED."

Hi,

I'm looking for some world population information, preferably
numerical (Although very good graphics would be nice).  I 
need to know how many people live within X miles of the coast
all over the WORLD.  I have some atlas maps showing in color
populaton density, but going from this to actual numbers is
difficult (to say the least).  Also, this wouldn't be accurate.
I would like to know within about +-5%.

Does ANYONE know where this type of data could be found?  Or
ways I could compute an estimate?  I know this information
must be somewhere!  Lastly, I'm in a hurry.  Worst case I'll
make an estimate from my map, but if any one has ideas, send 
them via e-mail to killoran@ll.mit.edu.

Thanks for any/all help!

I like the idea of a book of algorithms, and Chris Gold appears
to be going in the right direction I also endorse all that has been said about
 the 'Graphics Gems' series.

Unfortunately I suspect that too few of the GIS community are working
at the level of raw code to justify the effort of editing and
documenting such a collection. Stan Openshaw tried to get such a venture
off the ground several times in the U.K. to no avail. But that might
just be the U.K.

On the positive side I think that getting together such a collection
would bring together the computer scientists, who look to GIS as a
fertile source of hard (well, perhaps non-trivial would be more
accurate) problems, and the applied GIS commuinity who want a command
in their package to do things that are both predictable and
understandable. Neither of these are necessarily true of all GIS
software today where the algorithms are treated as proprietry secrets.

Final bit of negative thinking, only an established tenured academic
could possibly afford to do it. Duane has said before, when it comes
to tenure or assessment of publications code does not count.

We purchased 22 TM scenes from EOSAT last spring.  They were georeferenced
by STX, but not terrain corrected.  In checking some control points with GPS
and USGS 7.5 minute topographic maps, we are finding errors ranging from
30 to 500 meters (the terrain ranges from 900 to 2500 meters).  Has anyone
had experience with TM images georeferenced by STX?  They apparently
changed their algorithm for precision geocoding in January, 1992.  I am

Thanks for your most rapid response, and, yes, I agree with the points you make.
But what I fail to understand is the sense in which a scale can be quoted for
a database. What does 1:50,000 *mean* until its given some physical reality?

Am I being very naive here, and missing something obvious?  Anybody?

Sure, you should be able to run it off the CD (assuming it isn't just

running the smaller, frequently used stuff off the hard disk,
since Cd's are a full order of magnitude slower than most hard disks

i suggest you subtract the minimum map value from each cell and then
divide the remaining values by a reasonable scale factor.  then dump
(export) the row, column, value to a file.  use this file for cutting 1

There is an online system called the Global Land Information System (GLIS)
that contains information about AVHRR coverage as well as DLG's, DEM's,
and several other data sets.  Telnet to glis.cr.usgs.gov (152.61.192.54).
 The system is run by the USGS EROS data center and seems to be very well

I like the pincushion devices that are found in specialty toy
stores. They are a matrix of 4cm long, independent steel pins that move
freely in Z axis only. Think of it as a "bed-of-nails", only the nails
can move in Z! As an object is pressed against the bed of nails, the
object's 3D silhouette is formed and retained after the object is
removed. Now, replace the object with 3 axis "pen" and an instant terrain
model maker can be formed.

You might be able to define a new terrain measurement, the "Sealy" factor.
I'd prefer to sleep on a Kansas myself.  :-)

I've noted the recent discussion on "What is 1:50,000?" with great

"scale" represents (poorly) some VERY important characteristics of
the data - accuracy being one of those.

Surely we would be MUCH better off if we were to include accuracy as
an item in the data dictionary instead of scale.

And, for those who think that scale is good enough - what accuracy
is represented by a scale of 1:50,000?

I have not received the October issue of AAG newsletter.  So, I am
waiting to find out the context in which Martin Kenzer's comment on
GIS is quoted in the "Note from Ptolemy" column.  As a faculty of the
Geography Department at Florida Atlantic University, I would like
to make the following two points.

1) I wrote a response to Kenzer's comment and sent it to the editor
of Applied Geography for review.  The title of my manuscript is
"Geography: a place for GIS".  In addition to the quote pointed
out by Professor Marble, there were other statements in Kenzer's
comment indicating how GIS is "understood (or misunderstood!)" by
some geographers;
(By the way, according to the editor of Applied Geography, there
will be a response by Morgan Sant in the forthcoming issue of AG.)

2) Geography Department in the "College of Social Science" at Florida
Atlantic University has been active in developing its GIS curriculum
and its GIS lab.  This calendar year (1992), we have had about 100
students enrolled in GIS courses.  Our GIS lab operates PC's, Sun
workstation, and VAX for software such as Arc/Info, Idrisi, TransCAD,
and others.

Dr. Kenzer, who is a geography faculty member in the "College of
Liberal Arts" at our university's Davie Campus, has his views on GIS.
Geographers often do not agree with each other; and it is important to
hear from both sides.  Thank you for allowing me to take some bandwidth.
