I am in the process of investigating software which can link address
information in a database with physical location on a map.  I would like
to use it to, given a list of addresses, show the locations of these
addresses on a map, and for each address, be able to determine the closest
location to it amongst a group of locations distributed throuout the map.
(For instance, given an address I would like to find the closest
restaurant to this address among a group of restaurants.)

I read the recent Byte article about mapping software (January 1992), and
noticed GeoQuery 3.0.  Anyone used it?  What types of things have you used
it for?  Is it fully programmable, along the lines of a high-level language
database (e.g. FoxBase, Omnis 7).

Any system that I would put into use would have to have data available on
Vancouver, B.C., Canada, the surrounding metropolitan area and it would
be good to have data for the whole of southern B.C. and Vancouver Island
as well.  Is there ANY mapping program for the Mac (or even, yuck, DOS)
that can be configured with detailed data from these areas?

Thanks if you can help me out.

Geoff,

I've had a chance to perform some database mapping in the past and
have attempted to use both GeoQuery and Atlas Pro.  For street-level
mapping I would go with Atlas Pro.  At the time I was doing this
(about a year ago) GeoQuery did not support any street-level maps, it
could only plot people by their zip code.

If you are attempting get a national picture of your data by plotting
the address across many states then the zipcode-based plots in GeoQuery
would work fine.  However, if you are looking to plot addresses within
a particular county with resolution down to the street level you will
have to use a more ddetailed product like Atlas Pro.

The street-level maps are an extra item that you would have to order
through the company making the software.  These maps are produced on a
county level and typically cost around $500.  There is usually a choice
of multiple maps a given county, each with better clarity than the next.
Street-Level ETAK maps are produced by the government and are pretty
good but may have some streets in new developments missing and the 
graphical clarity is a little rough.  Many companies take these from
the govt and then clear them up and add additional street detail. Of
course, the price rises as you get better, more accurate maps.

Atlas Pro is made by:
