Leo Version 7 0 User Manual Glennon F Gagnon Kansas Geological Survey December 2008 Historical Overview LEO 7 0 is a computer program that converts Kansas Public Land Survey System PLSS legal land descriptions to geographic coordinates and vice versa The program is designed to run as a stand alone application allowing users to perform conversions without access to a networked environment A web based version of the tool will be available also under the name LEOWEB 7 0 Links are available at http www kgs ku edu software LEO The application is not a surveying tool and only provides an approximate conversion Written in Java the program is the latest of several applications developed at the Kansas Geological Survey designed to perform such calculations The first program was written in 1964 by Donald Good 1964 His program used 126 land locations and an arbitrary map coordinate system to test the possibility of using a computer to convert section township and range notation to Cartesian coordinates Good s program was written in FORTRAN II for an IBM 1620 computer Subsequent programs such as KANS developed by Charles O Morgan and Jesse M McNellis 1969 offered significant improvements including the ability to calculate latitude and longitude values KANS was written in FORTRAN IV and tested on an IBM 7040 at the University of Kansas Computing Center The program utilized 948 latitude and longitude control points and 962 township a
