While every effort is made to maintain this geographic data in an accurate format, the lines drawn from this data are fundamentally informational in nature and are not equivalent to survey grade. Geoprocessing has been applied to this specific web layer to allow faster drawing of lines which can further degrade the accuracy of their geometry. Finally, these parcels are used to create county tax maps which have the sole use case of giving assistance for local municipal assessors in the fulfillment of their duties, there is no warranty (expressed or implied) for any other use.
The PDF tax maps are organized by Municipality and Section number and are the same resources used to print the paper copies of tax maps that you might find in your local assessor's office. These tax maps are hosted on Oswego County's Image Mate Online website. You will need a compatible PDF viewer in order to display these maps.

description: These GIS files represent geographic boundaries for lands are under the protection of NYS Agricultural District Law, administered by the New York State Department of Agriculture and Markets. The data are derived from 1:24,000 scale maps of individual districts showing boundaries that correspond to tax parcel data. District data is joined into a file representing an entire county. Note that 2003 legislation allows lands to be added to districts on an annual basis. Electronic data provided here may predate those additions. It is important to reference the current tax parcel list for each district to confirm the precise agricultural district boundary. Tax parcel detail and secondary rights-of-way are not included in this dataset. Rights-of-way for state and federal highways, railroads and utilities are only included when they are delineated on the original 1:24,000 scale maps. The data files are in ArcInfo 8.3 export file format.; abstract: These GIS files represent geographic boundaries for lands are under the protection of NYS Agricultural District Law, administered by the New York State Department of Agriculture and Markets.
