This Traffic Control application demo (viewed as a Java applet). This applet is portable, performs exceptionally well and is highly compact -- about 155K! The applet could be easily customized via simple text files, without any modification to code.
This application is about 155K,including the vector font, the icons and all interactive behaviors. Maps are stored in a binary format tailored for map poylines resulting in optimum compression and faster downloads.
The map data set parameters are set from user-defined text file which is read by the applet at runtime so it is easy to reconfigure without changing code.
The maps are generated from industry standard shape files with complete control over colors, edge-widths, layering, etc.
The Symbols are GMS models and are dynamically instantiated from DATA files. The DATA files contain records describing each icon and its attributes.
