Became instructor at the pilot school of Karlskrona in 1745. In an official communication pointing out the inadequacy of Swedish sea charts, Wallman called for more astronomical observations and more careful measurements.

A successor summed up Wallman's career: 'Nobody before or after has made such great personal contribution to the sounding of our coasts'
