Opening the Edwardsville GIS map
For acreage around Glen Carbon, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
The viewer Madison County publishes
Begin with the Madison County parcel viewer; it covers every tax parcel from Pontoon Beach to South Roxana. When a rural tract has no street number, pan along Interstate 255 until the lines appear, then click inside the one you want. Around Glen Carbon, the parcel card normally shows the owner of record, assessed acreage, a parcel ID and in many cases the last transfer.
Edwardsville and the county around it
Edwardsville lies within Madison County, Illinois, so its parcels are on the county's map. Edwardsville is also the county seat, which puts the county Recorder of Deeds (in many counties the County Clerk and Recorder) close by. For a parcel near Pontoon Beach, city or town hall handles things like zoning, permits and utilities within town limits, but the county runs assessment and recording. Acreage past the town limits toward South Roxana usually answers to county rules, not municipal ones.
Search tips
Acreage around Pontoon Beach might not have a street number, so zoom in from Interstate 255 and click the outline. Closer to South Roxana, searching by parcel number never misses, and it's printed on tax bills.
When a parcel crosses a boundary
Madison County touches Bond County, Clinton County, Jersey County, Macoupin County, and Montgomery County, and each of those keeps its own parcel map. Acreage along the edge near South Roxana may be split in two county records, so open the adjacent map too. Around South Roxana, the Platbookmapper state page lists each bordering county map for Illinois.
Who handles what
For assessment questions about property around Glen Carbon 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 South Roxana are for the local planning and health departments, town or county, depending on location.
Sections, lots and bearings

Keeping a record

Aerials, labels and overlays
If the land is near Hartford, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
Field tips
Most viewers work in a phone browser, which helps when you're standing on land near Roxana, so load it before you lose signal. A saved image of the lot near Pontoon Beach and its lines keeps working without signal.
A word on accuracy
Parcel lines are drawn for taxes, not measured on the ground, so the edge of a yard near Glen Carbon often sits a few yards off the line on screen. With a lot near South Roxana, owner names and values update on a schedule, so a deed recorded last month may not show yet.
Troubleshooting the viewer
If the viewer stalls on a phone near Maryville, switch browsers or turn off pop-up blockers; links occasionally change, and our directory page keeps the current one.
