COORDINATE TRANSFORMATIONS

IN 1965 COMPUTER PROGRAMS WERE WRITTEN IN FORTRAN II FOR CONVERTING GEOGRAPHIC COORDINATES TO STATE PLANE COORDINATES OR THE INVERSE FOR USE ON THE IBM 1401 (12K) DATA PROCESSING SYSTEM. TWO SEPARATE PROGRAMS WERE NEEDED FOR THE TRANSFORMATIONS BECAUSE OF THE LIMITED CORE STORAGE AVAILABLE. ONE PROGRAM PERFORMED THE FORWARD AND INVERSE COMPUTATIONS FOR THE LAMBERT CONFORMAL PROJECTION AND THE OTHER FOR THE TRANSVERSE MERCATOR PROJECTION. IN 1967 IT WAS DECIDED TO COMBINE THE TWO PROGRAMS INTO ONE FOR USE WITH THE IBM 360 SYSTEM. THE PRESENT PROGRAM WHICH CONSISTS OF A CALLING PROGRAM AND SIX SUBPROGRAMS HAS BEEN WRITTEN IN FORTRAN IV, AND CAN BE READILY ADOPTED TO OTHER COMPUTER SYSTEMS. /AUTHOR/
