For any lot around Erin, the Elmira GIS map shows the outline, the owner of record and a parcel ID. Covered here for Elmira: where that map lives, the fastest ways to search, and what to double-check with records.
The official viewer behind the Elmira GIS map
If the land is near Van Etten, some cities also run their own GIS portal for utilities or zoning; that can add detail on top of the county map.
Pulling up a parcel
Lots and tracts near Southport can be looked up on the Chemung County ArcGIS parcel map, a viewer that needs no account. When a rural tract has no street number, pan along the nearest road and click the parcel itself, which applies near Southport as much as anywhere. On ground around Horseheads, write down the parcel ID while you have it open; every office in the county will want it.
Elmira and the county around it
Elmira sits in Chemung County, New York, which means parcel data comes from the county. As the county seat, Elmira hosts the courthouse, which puts the County Clerk close by. On ground around Southport, city or town hall handles things like zoning, permits and utilities within town limits, while the county keeps the tax map. Lots just outside the city limits out by Erin usually falls under county rules rather than the town's.
Field tips
The parcel map usually runs in a mobile browser, which helps when you're standing on land near Horseheads, but coverage can be spotty out of town. A saved image of the lot near Horseheads and its lines keeps working without signal.
Places you'll see on the map
Elmira serves as the county seat, which is where the courthouse records live. You'll also find Southport, Horseheads, Big Flats, and Erin, each with its own cluster of lots. Roughly 81,325 people live in Chemung County (Census estimate, 2023) on roughly 407 square miles. Chemung County dates to 1836, which matters when you trace an old farm's title.
Saving what you find
Save a screenshot of the lot near Horseheads and its record panel, which helps later when you ask the assessor or a title company.
Limits of the parcel data
Parcel lines are drawn for taxes, not surveyed, so the edge of a yard near Van Etten may sit several feet off the line on screen. Closer to Erin, records update in batches, so a deed recorded last month might lag behind.
Search tips
Vacant ground near Ashland may lack an address, so zoom in from the nearest road and click the outline. On ground around Horseheads, searching by parcel number never misses, and it's printed on tax bills.
Where the recorded documents are
When the details count, get the recorded deed through the County Clerk; the parcel map near Big Flats only summarizes it. On ground around Van Etten, have ready the document number from the tax record and the lookup takes minutes.
Sections, lots and bearings
Older tracts around Van Etten commonly use metes-and-bounds descriptions, which trace the boundary call by call. Town lots near Van Etten usually use lot and block from a recorded plat instead, making them easier to find. Copy the legal description from the record for the parcel near Southport when you talk to a surveyor.
When a parcel crosses a boundary
Chemung County borders Schuyler County, Steuben County, Tioga County, Tompkins County, and Bradford County, PA, and each of those keeps its own parcel map. A tract near the line by Van Etten can be split across two assessors' files, so look at the neighboring map too. For property near Erin, the Platbookmapper state page links every bordering county map across New York.
Which office to call
If the acreage or value on a parcel near Big Flats looks off belong with the county Real Property Tax Services office, which maintains the tax roll. Zoning, permits and septic questions near Erin need the planning or permitting office, and the answer depends on jurisdiction.
Browser tips
When the map won't open around Van Etten, switch browsers or turn off pop-up blockers; the Platbookmapper county page tracks the current link.
Layers worth turning on
Out toward Ashland, layer lists often include zoning, flood zones, city limits, school districts or contours; not every viewer has them all.
What the record panel tells you
Recent sales on nearby lots around Van Etten give a rough idea of values; they're not an appraisal.

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.
