When land near Bardolph catches your eye, the Macomb GIS map lays out lines, owner names and parcel numbers. In this Macomb guide: where that map lives, how to search it, and the limits worth knowing.
Opening the Macomb GIS map
In most places the county maintains the parcel layer, which makes the McDonough County WTH GIS map the main source for lots in Macomb.
Where the parcel data lives
Go first to the McDonough County WTH GIS map; it includes every assessed parcel from Sciota to Good Hope. For a parcel near Tennessee, type a street address, an owner's name or a parcel number, and the viewer zooms to the match. In and around Tennessee, the parcel card usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
The paper trail behind a parcel
For anything that matters, get the recorded deed through the county Recorder of Deeds (in many counties the County Clerk and Recorder); the parcel map near Bardolph only summarizes it. For a tract near Bardolph, have ready the instrument number shown in the record panel so staff can find the deed fast.
Browser tips
When the map won't open around Tennessee, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
When a parcel crosses a boundary
McDonough County touches Fulton County, Hancock County, Henderson County, Schuyler County, and Warren County; every one of them runs a separate parcel map. A tract near the line by Industry may show up in two county records, so check the neighboring map before you assume the acreage. Near Sciota, our state page lists each neighboring county map for Illinois.
City limits and county records
Macomb lies within McDonough County, Illinois, which means parcel data comes from the county. The town is also the county seat, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by for land near Good Hope. Out toward Bardolph, city or town hall handles matters such as zoning, permits and utilities inside its limits, and the county still keeps the parcel and deed records. Land beyond the city limits near Industry generally answers to county rules rather than the town's.
Using it on a phone
Most viewers work in a phone browser, useful out on a road near Bardolph, so load it before you lose signal. A saved image of the lot near Colchester and its lines is a good backup.
Searching the map
Vacant ground near Industry may lack an address, so zoom in from US Route 136 and click the outline. For a parcel near Sciota, searching by parcel number never misses, and it's printed on tax bills.
Aerials, labels and overlays
For a home near Tennessee, layer lists often include municipal boundaries, floodplain and sometimes zoning; availability varies.
How land is described here
Illinois follows the Public Land Survey System, so rural legal descriptions near Sciota cite section, township and range. A standard section is about one square mile, roughly 640 acres, with 36 sections to a township, though corrections make some sections near Bardolph odd-sized. Write down the legal description for the tract near Sciota before you request a deed or survey.
Before you lean on the lines
The acreage figure is a tax-roll number; only a licensed surveyor sets the real corners on land around Industry. Closer to Bardolph, owner names and values update on a schedule, so a deed recorded last month might lag behind.
Keeping a record
Print or screenshot the parcel near Tennessee with its ID visible, so you have it when calling an office.
Inside the parcel card
Recent sales on nearby lots around Good Hope give a rough idea of values; an appraiser is the real authority.
Which office to call
For assessment questions about property around Industry are handled by the Supervisor of Assessments, working with township assessors, since that office keeps the assessment data. Questions about what you can build around Industry go to planning, building or health offices, town or county, depending on location.

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.
