A SERIES OF PROGRAMS FOR DRAWING MAPS AND PLOTTING DATA ON THEM. THE 

 PROGRAM OPERATES UNDER A SIMPLE COMMAND LANGUAGE WHICH ENABLES THE US- 

 ER TO REFER TO HIS DATA AND THE MAP DATA BY NAME. THERE ARE ElEVEN 

 PROJECTION OPTIONS AVAILABLE IN THE BASIC TRANSFORMATION SUBROUTINE. 

 A MORE ADVANCED PACKAGE (WITH SEVERAL PROJECTIONS TAKING THE LllIPTIC- 

 ITY OF THE EARTH INTO ACCOUNT) IS UNDER DEVELOPMENT. AUTHOR — DR ROB-
