Want a copy of the Hanson County plat book? It's a printed atlas of landownership, usually by township, popular with hunters, farmers and buyers near Emery. What this Hanson County guide covers: what's in a plat book, where to find editions, and how the county viewer fills the gaps.
Tracking down a Hanson County plat book
On ground around Fulton, a plat book is a privately published atlas, with owner names on each tract, usually township by township.
The viewer Hanson County publishes
Go first to the District III regional GIS map; it covers every tax parcel from Farmer to Rockport Colony. When a rural tract has no street number, follow the nearest road on the aerial and select the outline, for land near Rosedale Colony included. If the land is near Oak Lane Colony, the record panel typically gives the owner of record, assessed acreage, the parcel number and in many cases the last transfer.
Reading the legal description
South Dakota uses the Public Land Survey System, which means a tract near Farmer is described by section, township and range. A standard section is about one square mile, roughly 640 acres, and a township holds 36 of them, though sections near Rosedale Colony can be irregular. Write down the legal description for the tract near Rockport Colony for any title or survey request.
Offices that can help
Recorded documents for a parcel near Oak Lane Colony come from the Register of Deeds, usually searchable by name or document number. Zoning, permits and septic questions near Emery go to planning, building or health offices, depending on whether the land is inside town limits.
Land on the county line
Hanson County touches Davison County, Hutchinson County, McCook County, Miner County, and Sanborn County, all with their own assessor records. A tract near the line by Emery may be split in two county records, so open the neighboring map as well. If the land is near Epiphany, our state page links each neighboring county map across South Dakota.
Common uses
Farmers, hunters and appraisers near Millbrook Colony use plat books for a big-picture view of who owns what.
Buying or borrowing a copy
Not every county has a current edition, try the county extension office, recorder's office or library near Farmer.
A homemade atlas
Print parcel views near Epiphany township by township and keep them in a binder for the truck.
Using the parcel viewer instead
For a home near Fulton, the District III regional GIS map is updated more often than any atlas, across the county.
Plat book vs. recorded plat
If the land is near Emery, don't confuse the atlas with a recorded subdivision plat: the recorded plat at the Register of Deeds is a legal document, while the atlas is a reference.
Using it on a phone
The parcel map usually runs in a mobile browser, handy when you're parked on a road near Farmer, but coverage can be spotty out of town. A printout of the tract near Rockport Colony keeps working without signal.
Recorded documents worth pulling
When the details count, pull the recorded deed through the Register of Deeds; the viewer just points to it, which applies near Epiphany as much as anywhere. Long-held tracts near Oak Lane Colony may trace back through many deeds, and a title company earns its fee on a real sale.
A word on accuracy
For land near Fulton, the acreage figure is an estimate; only a licensed surveyor sets the real corners on the ground. Closer to Rosedale Colony, owner names and values update on a schedule, so a deed recorded last month may not show yet.

Not a survey. County GIS and tax parcel maps are assessment and planning layers. They are not a substitute for a recorded plat, deed, or licensed survey, especially for fences, setbacks, or boundary disputes.
