[Mapserver-users] GPS Coordinate Mapping

[Kasey Kirkham]

Hi all,

I'm currently working on a GPS-oriented mapping application(with much
help from Chris over at DM) using mapserver and php/mapscript(4.0.1 and
1.177, respectively).  I need to be able to select coordinates out of a
database and plot those coordinates over a map.  I can zoom to a given
extent through mapscript, but I'm at a loss as to how I can draw the
points on the map.  I was referred to this document:
http://mapserver.gis.umn.edu/cgi-bin/wiki.pl?VirtualSpatialData
but I would like something that left connecting to the database and
preparing the points up to me.  It might also be necessary to create
layers with more complex shapes from a variable number of points.

So, what mapscript objects/methods can be used to create shape files(or
even the "shapes" themselves...) and to add them to the map at execution
time?  Of course, if I'm barking up the wrong tree entirely, some
redirection would be equally appreciated.

Thanks for you help,
Kasey Kirkham
