From the lots in Creekside to the back roads near Coral, the Indiana County plat map shows who owns what and roughly where the lines fall.
Keep reading for the viewer link, how to search it, what the parcel data means, and how deeds and plats back it up in Indiana County.
Opening the Indiana County plat map
The Indiana County ArcGIS parcel map is the county's own public parcel viewer; it runs on an Esri ArcGIS web map. Use the search box to find an Indiana County parcel by owner name, address or parcel number, or zoom in and click a lot to open its record. The same link lives on our Indiana County county page, along with links for the surrounding area.
Where Indiana County deeds and plats are kept
Every line on the Indiana County map traces back to a recorded deed or plat, and the county's recording office keeps those documents. Check the county government website to see which office records deeds for land near Coral. When the chain of title matters for land near Blairsville, ask for the full deed history or hire a title company in Pennsylvania.
Indiana County at a glance: towns and land
Armagh, Blairsville, Cherry Tree, and Clymer fill out the town list, and Indiana is where the county seat sits. The map also labels unincorporated places, Alverda, Black Lick, and Chevy Chase Heights among them. The county dates to 1806, and older deeds may still refer to landmarks from that era. About 83,094 people lived in Indiana County in 2023, according to Census Bureau estimates, on roughly 827 square miles. That density means a real mix on the map: platted neighborhoods near Creekside, and larger tracts on the rural roads. Water features such as the Conemaugh River and Kiskiminetas River shape where lots fall and where floodplain sits.
Who uses the Indiana County parcel map
Different people come to the Indiana County parcel map for different reasons.
- Before an offer, buyers in Indiana County pull the parcel to confirm the lot dimensions and look for anything odd, like a flag lot or a shared drive.
- For a new build outside Ernest, the parcel record supplies the lot size and legal description a site plan needs.
- Bowhunters and waterfowlers around Creekside use the parcel layer to see which owners control a creek bottom, a woodlot or a field edge.
Acreage and vacant lot search
Looking for open ground between Ernest and Cherry Tree? Try this:
- Turn on the photo basemap and work outward from Ernest one road at a time, flagging parcels with no buildings.
- Click each empty tract near Coral and note the owner, acreage and mailing address.
- Compare the record's land value against similar parcels on the same road out of Ernest.
- Confirm legal access. In Indiana County, as anywhere, a parcel with no road frontage depends on an easement.
- Check the flood layer and ask about septic and permits; open land in Indiana County isn't automatically buildable.
Before you buy near Ernest, read how to tell if land is buildable.
Are the Indiana County property lines accurate?
Parcel boundaries on the Indiana County viewer are drawn to keep tax accounts straight, so small offsets from the true line are expected. Pennsylvania is a metes-and-bounds state. Rural deeds in Indiana County describe boundaries with bearings, distances and landmarks rather than a square grid, so parcel lines are often irregular. For a fence, an addition or a dispute in Indiana County, budget for a licensed survey; it's the answer a court or a lender will accept.
Before you rely on the data
If a tract near Armagh changed hands recently, the recorded deed is more current than the map. Acreage on the Indiana County map is a tax figure; a survey is what a lender or buyer should rely on.

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.
