Steel tapes, which were introduced in the late 1800's for precise geodetic surveying, had high coefficients of expansion and were used during the more stable night-time temperature hours for base line measurement. Invar was a material with a very low coefficient of expansion which allowed the measurement of bases during the day. Distance measurement techniques did not experience another major improvement until post-World War II with the modification of electronic aircraft navigation systems for precise distance measurement.)
