A computer technique is described that converts township, range, section, and tract locations into latitude-longitude coordinates. Using an IBM 1620 with disk storage drive, the program will calculate latitude-longitude coordinates at the rate of about 75 points per minute. The average error of the conversion is about 2.5 seconds of latitude and 2.8 seconds of longitude, and the maximum error is about 7 seconds of latitude and 8 seconds of longitude. The conversion technique is suitable for most townships in the western United States. Townships that are very irregular are not suitable for this coordinate conversion program, but an extension of the logic of this program could be used to calculate coordinates in irregular townships.
