Welcome to the Society of Land Surveyors of Iowa

The Society of Land Surveyors of Iowa was formally founded in 1957 in Ames, Iowa. Annual meetings for the betterment of land surveying can be traced back prior to that time.

Through the years, technological advances have changed the appearance and product of the professional land surveyor, but the core principle of impartially protecting interests in land by superior knowledge of history, related law, evaluation of evidence, and prior surveys has not changed.   SLSI is committed to keeping the professional land surveyor abreast of the latest in technology while holding to this core principle.

Basically, anything related to land location and use will generally require the services of a Professional Surveyor.
