[2003] How to design a machine distribution map?

I was lack of good idea to design a machine distribution map using VS.2003. My basic design idea is  every machine represented by circle shape distinguishes the status with color (using system. drawing class, User have to predefine the location of machine when key in the machine description). When a machine discovered breaking down, user required to update the database status field to ‘Breakdown’. The map will auto refresh for every 1 second. After the status of machine changed, the map will appear a flash red point to inform the maintenance coordinator to take the corrective action against it.

Question: Any better idea for designing some kind of this system?

I have post it before but I didn’t explain more detailed.

Thanks :thumb:
