Two distinct map layers. The geographic background comes from USGS The National Map (terrain, streets and waterways), with an optional OpenStreetMap street view. County parcel outlines load separately from Erie County's public Parcel Query service (source S22) when requested or opened through a parcel link. Outlines are aligned to geographic coordinates; neither the basemap nor the county tax-map polygon certifies a legal survey, Seneca Nation boundary, federal land status, or jurisdiction. Public map-tile providers receive ordinary browser requests for the currently displayed area.

Historical and contemporary geographic sources
Current tax mapping
Erie County Parcel Query
Public tax-map polygons by SBL; geometries may be updated. County boundary features are not certified deeds or federal sovereign boundaries.
1844 archival reference
Buffalo Creek historical map
Shows historical reservation sale geography, not present reservation or restricted-fee status. Do not overlay it on current SBLs as a legal boundary without georeferencing and survey controls.
Nation official sources
Nation maps and transportation
Official Nation boundary and transportation materials must be consulted in their own context; mapping service jurisdiction and federal title are separate questions.
Planned Phase 2 work
Certified tract-to-SBL crosswalk
Obtain deeds, federal status decisions, official tract exhibits and recorded surveys before publishing jurisdiction or restricted-fee overlays.
