Yes, it would work well. As part of your system, you will be feeding a
database with point information (historic and current) about vehicle
locations. You would define some queries in that database to extract only
the latest time-based position. Then, in MGOS, you would point your layer
definition(s) to these queries where the symbols would be drawn directly
from the x,y data in the database using the FDO ODBC data provider. A
little programming using the MGOS API would be necessary to refresh the
layers at the desired time interval, be it every 10 seconds or every 5
minutes or whatever. If the latest point data has changed since the last
refresh, then the vehicle symbols will shift accordingly. Or, you might be
able to write a trigger that would call a stored procedure if new point data
is added and then force a refresh from the server-side.

Subject: [mapguide-users] MapGuide for an AVL app?
I'm currently evaluating web based mapping software for an AVL system. Could
somebody let me know if Mapguide OS is a suitable dev platform to develop a
web based Vehicle tracking system. Is it possible to dynamically plot
coordinates on the MapGuide OS platoform.
