But all maps present the selected data using the same layout, colors, and marker types. AIRS Graphics system administrators periodically generate some types of AG maps and make them available for viewing. Based on your choices, AIRGraphics software selects the appropriate data, manipulates it as needed, and creates a graphic representation of it. Producing Graphics Mainframe AIRS Graphics has interactive menus that make it easy to select a type of graphic, and to specify options that determine its contents. Every menu checks the values you enter and, if there is a problem, tells you what is wrong.
Every menu has a help screen that explains the menu's purpose and how to use it.
Once the desired graphic has been specified, the color graphic is displayed on your mainframe terminal. AIRGraphics on the Web provides similar capabilities and options. AGWeb uses web page forms instead of menus, and it displays maps and charts in your browser. After a map or chart is displayed, there are several options for producing additional types of output. Mainframe AIRS Graphics is is available to EPA staff and contractors, state environmental agencies, and a few other organizations that have an account on EPA's mainframe computer.
