The Map Composer allows users to perform many data display and query functions, as well as to create standard ARC/INFO map compositions, graphics files, and Calcomp plotter files. The intent of the program is to present users with a small subset of core ARCPLOT commands in a user-friendly graphical environment, making ARCPLOT less intimidating for the new user and more convenient and faster for the experienced user.
