Oh, one big ommission on my part:
=20
Some fo the things you talk about could potentially need a Java applet:
=20
The Distance measuring tool can be implemented on the client using a =
Java
applet, there are a few alreadin existence that probably provide this
functionality (I don't know for sure, I have severe allergic reactions =
to
Java in the browser). Otherwise you can always go back to the server =
and
figure it out there obviously. Some people have implemented in =
JavaScript,
such as the Chameleon toolkit ( http://www.maptools.org
<http://www.maptools.org> ).
=20
The buffer you're pretty much going to NEED a Java applet, as I've =
never
heard of any way to draw circles in a browser in any other =
cross-browser way
(There's also the possibility of using SVG or Flash interfaces =
actually, but
that may be less cross-platform).

Subject: [Mapserver-users] Researching the Capabilities of MapServer
Hello all,=20
I am new to the world of MapServer, and have many questions, mostly
regarding the capabilities of MapServer. At this point I am merely
researching the possibility of using MapServer as a replacement for an
existing ArcIMS setup. I have set up the basic Itasca demo, and have =
it
(mostly) working with some of our own data. From what I have seen, =
basic
.cgi MapServer is not able to perform many of the tasks necessary (see
below). However, I am beginning to learn of the other available =
projects
(e.g. GeoServer, MapScript, etc.) that work with MapServer to do many =
of
these things. At this point, I have not used any of these other tools, =
and
no next to nothing about them (the MapServer that I have set up =
currently
allows only the basic .cgi functionality [pan, zoom, query] of the =
Itasca
Demo.) I would like to know if the features listed below are possible, =
and
if so, how I would go about implementing these features (e.g. do I need =
PHP,
dhtml, GeoServer, MapScript, etc., etc.)
What I would like is a full featured application which can perform the
following tasks:=20
- search based on text field(s) and then zoom to matching
record(s) (e.g. enter a city name and a street name, and zoom to that
street)
- geocode addresses (e.g. interpolate positions along a street
based on from/to address ranges and zoom to that point)
- search based on topology (e.g. find where two streets
intersect and zoom to that location)=20
- have an "identify" tool which pops up attributes of feature(s) =
when
they are clicked on=20
- measure distance between points selected by the user=20
- draw buffers around a clicked point based on a user defined =
radius=20
- highlight a selected feature and retain its highlighting until =
the
user "clears" it=20
Also, I would appreciate a brief run-down of the applications which =
work
with MapServer (e.g. GeoServer, MapScript, etc.), how they relate to
MapServer (and each other), and what each one does.
I realize this email covers a broad range of topics, and is asking a =
lot--so
thanks in advance for helping me out with all these questions!
