regardless of whether you are displaying world-wide or regional data. You
could approach it a couple of different ways. First, you could author one
map that has all of your layers contained in it and then control their
availability through zoom thresholds. Or, you could approach it from a
drill-down perspective. You start with the world view, the user clicks the
hyperlink for the country, a new web layout or map is then substituted in the
main window or a new window opens displaying that country. From there, you
could click on hyperlinks for city's and so on. Both of these
options could be accomplished using "out-of-the-box"
functionality.</FONT></SPAN></DIV>

<DIV dir=ltr align=left><SPAN class=405533217-18092006><FONT face=Arial
color=#0000ff size=2>There are many other approaches that you could take using
the API. For instance, from your world map, if the user zooms in, send the
view envelope to the server and determine which layers have extents that
intersect that envelope and only display those layer names in the legend as
being available. A good approach would be to design a database that holds
all of your layer metadata and then you could build a dynamic, data driven
application.</FONT></SPAN></DIV>

<DIV><FONT face=Arial size=2><SPAN class=486055708-18092006>I am just starting
to look at MapGuide as a possible solution for my web GIS needs. It looks very
promising.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN class=486055708-18092006>I have a couple of
questions that someone may be able to help with.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN

<DIV><FONT face=Arial size=2><SPAN class=486055708-18092006>1) All of the
example sites I have seen seem to be related to city layouts/planning. Are there
any other examples with different datasets out there? I am specifically looking
at displaying my data coverages which are distributed all over the world, so
therefore on a totally different scale from those examples I have already
seen.</SPAN></FONT></DIV>
<DIV><FONT face=Arial size=2><SPAN
class=486055708-18092006></SPAN></FONT> </DIV>
<DIV><FONT face=Arial size=2><SPAN class=486055708-18092006>2) Also is it
possible to have multiple instances of the viewer running on the same site? For
example if I wanted to have separate pages to display say all my data in Egypt
and all my data in Argentina. Taking this one step further, could I even have
separate pages for every country in the world? Obviously this might not be
desirable from a design point of view, but is it technically
possible?</SPAN></FONT></DIV>
