Hi John,

you can link to mapblast ( http://www.mapblast.com/ )

You can do it two ways : 

if you don't know a lot about HTML and how to contruct a URL which
contains parameters for CGI-scripts (or other scripts), go to maps,
click 'advanced search' (left on screen), type in the lat/lon, get the
map, click on 'maps for your site' (at the bottom), and look for the
option 'free links to mapblast'. Read the info there, and copy the URL
to your page. This way you link to mapblast. Please read the 'terms of
use' to see if your intended use is allowed by mapblast.

If you know enough about HTML and how to construct a URL with parameters
for scripts, have a look at the example HTML for a map of new york below
: (I split up on several lines, but normally it's one long line without
extra spaces ! Also don't forget the '?' and '&' symbols)

-----------------HTML---------------------------------------------------
<B>Click here to see a map of : new york</B><BR>
<A href="http://www.mapblast.com/myblast/map.mb?
CMD=LFILL&IC=40.755486:-73.986148:8:&CT=40.755486:-73.986148:358000&
GAD3=New+York%2c+NY&GAD4=USA&W=456&H=259&AD3=new+york&AD4=USA&Zip=10036">
<img src="http://a328.g.akamai.net/f/328/1088/1d/www.mapblast.com/
myblast/images/corporate/rect_logo.gif" 
WIDTH="127" HEIGHT="34" ALT="" BORDER="0">
</A>
----------------End HTML-----------------------------------------------

This HTML-code will place a button from mapblast on you webpage (img
src="http://..../rect_logo.gif") and link it to the map and place of
your choice ( a href="http://...../map.mb?......). Looking at the url
you can discover the two most important parameters for you to change : 

CT=40.755486:-73.986148:358000     = these numbers represent the maps
centre lat:lon:scale (the higher the scale, the bigger the visible
area.)

IC=40.755486:-73.986148:8:         = these numbers represent the icons
lat:lon:type:extra parameter. Type 8 is the cross you see. Other types
exist, to find out, click on 'customize' (below map), and set the icons
and parameters to what you want, click update or finish, and have
another look at the url of the map image. That should learn you enough
about the different parameters.

Mapblast uses NAD83 inside the US and WGS85 for the rest of the world.

If you have a database of the coordinates, you can even use an 'asp',
'php' or some access script to generate the URL's for you. I did this
for a webpage with restaurants in my home town (only for internal use).

Good luck,

Geert.
