S.D. Codified Laws § 10-10-5
The person employed pursuant to § 10-10-2 shall make a classification of all lands and other real estate as a basis for fixing values for taxation purposes. In making such classification, he shall personally inspect such real estate and place each legal subdivision in its proper class, making the proper distinction between each legal subdivision as to topography, soil, location, and other factors that may reasonably enter into valuation. He shall enter such classification in a permanent record which shall be open to examination and inspection by any interested taxpayer. In working out a classification of all lands for taxation purposes, he shall hold hearings in convenient places within the county for the purpose of obtaining information from local property owners to aid him in working out an equitable classification for taxation purposes.
