Who keeps the Elmira plat map
For land around Big Flats, look for the plat book reference on the parcel record; bring that to the recorder's office or its online index.
Opening the official parcel viewer
Go first to the Chemung County ArcGIS parcel map; it maps each assessed parcel in the county, Van Etten included. If the land is near Van Etten, put in a street address, an owner's name or a parcel number, and the matching parcel lights up. Out toward Van Etten, a pop-up or side panel usually lists the owner of record, assessed acreage, a parcel ID and often a sale date.
Elmira, NY: the basics
Elmira sits in Chemung County, New York, and the county assessor maps its lots. As the county seat, Elmira hosts the courthouse, handy when you need recorded documents. For land near Southport, 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. Lots just outside the town limits toward Ashland generally falls under county rules rather than the town's.
Where the recorded documents are
The map is an index, not the title: recorded deeds, subdivision plats and easements covering ground around Big Flats sit with the County Clerk. Long-held tracts around Big Flats can sit on a long string of deeds, and a title company can sort it out on a real sale.
Plat map vs. parcel map
The tax map on the Chemung County ArcGIS parcel map is a summary, while the recorded plat is the legal document.
When there's no plat
Acreage around Horseheads outside a subdivision may have no plat at all; look for a recorded survey for land near Erin.

Reading the legal description

What a plat shows
If the land is near Erin, the sheet usually includes lot and block numbers, dimensions and bearings, street rights-of-way and easements.
What the map can't tell you
Parcel lines are drawn for taxes, not surveyed, so a fence near Southport often sits some distance off the line on screen. For a parcel near Van Etten, records update in batches, so a deed recorded last month might lag behind.

When a plat changes
An amended plat may change lots around Van Etten, so check for later filings; street vacations near Horseheads show up in the records too.

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.
