Hirvonen R.A. participated in 1930s building and measuring the Finnish landscape to higher accuracy than before by building triangulation measuring towers and developing new mathematical algorithms for the manual calculations.

In 1947 he led the team of Finnish scientist to Brazil to measure the distance between South America and Africa.
