<div>Thanks Andy for the info, very useful for my evaluation, I also have a few other clarifications : must I use Autodesk Mapguide Studio to develop the app? the preview version doesn't support anything much (specially database connectivity). So is there an alternative to MGS or preferably an Open Source option :).

<div>Do you know any other similar apps developed using MGOS? where I might be able to look at a sample to get an idea.</div>

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.

<div>Hello,</div>
<div> </div>
<div>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.
</div>

<div>Thx</div>
