An Allegany County parcel question can get confusing fast because the answer may live in more than one county office.
The county Real Property page lists tax-map products, filed survey map copies, oil and gas maps, deep-well records, and county GIS files. The GIS/County Mapping page says Allegany County maintains GIS data in various offices, with the Planning Office maintaining data such as tourism, streets, and streams, and using NYS GIS Clearinghouse aerial imagery as base imagery. The plain next step is to separate your question.
For boundary shape, start with the county parcel map and Real Property tax maps. For a filed survey, ask about the recorded survey image.
For oil, gas, well, or right-of-way history, ask whether the specialized map category is the right record before relying on a listing map. Bring the parcel number, owner name, road name, or document reference if you have it. That gives the county office a better starting point and keeps you from treating a tax-map outline like a survey or a legal opinion.
This is especially worth slowing down for rural land, older deeds, stream edges, and road frontage questions. In Allegany County, the map may start the conversation, but the record type decides how much weight the answer can carry.
