The Tioga County Geographic Information Tool is intended to be a parcel map viewer with additional layers of information of special interest to property owners. The parcel boundaries do not appear until the user zooms in on the map. Other layers can be turned on and off using from the layers list which can be exposed by clicking the Layer button in the upper right corner of the interface. A button at the bottom of the viewer opens a table viewer which can be used to explore the data related to each of the map layers. The table includes tools for filtering the data and selected records may be exported to a CSV file which can be opened as a text file using spreadsheet software. By default, clicking in a parcel brings up a popup of the parcel's attribute information. Popups for other layers can be enabled through the layer list. Other buttons allow the user to search for street addresses in Tioga County NY, locate the user's position using the GNSS capability of mobile devices, changing the base map, measuring distances and areas, identifying the coordinates of any location (a function of the measure tool), and displaying a legend.

Publication Date: April 2025 2024 Parcel Data. Updated annually, or as needed. The data can be downloaded here: https://gis.ny.gov/parcels#data-download. This feature service has two layers: 1) NYS Tax Parcels Public, and 2) NYS Tax Parcels Public Footprint which contains polygons representing counties for which tax parcel polygons are available in the NYS Tax Parcels Public layer. County footprint polygons display when zoomed out beyond 1:37,050-scale. Tax parcel polygons display when zoomed in below 1:37,051-scale. The NYS Tax Parcels Public layer contains 2024 parcel data only for NY State counties which gave NYS ITS Geospatial Services permission to share this data with the public. Work to obtain parcel data from additional counties, as well as permission to share the data, is ongoing. To date, 36 counties have provided Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow Geospatial Services to redistribute their data must be obtained directly from those counties. Geospatial Services' goal is to eventually include parcel data for all counties in New York State. Parcel geometry was incorporated as received from County Real Property Departments. No attempt was made to edge-match parcels along adjacent counties. County attribute values were populated using 2024 Assessment Roll tabular data the NYS ITS Geospatial Services obtained from the NYS Department of Tax and Finance’s Office of Real Property Tax Services (ORPTS). Tabular assessment data was joined to the county provided parcel geometry using the SWIS & SBL or SWIS & PRINT KEY unique identifier for each parcel. Detailed information about assessment attributes can be found in the ORPTS Assessor’s Manuals available here: https://www.tax.ny.gov/research/property/assess/manuals/assersmanual.htm. New York City data comes from NYC MapPluto which can be found here: https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page. Thanks to the following counties that specifically authorized Geospatial Services to share their GIS tax parcel data with the public: Albany, Cayuga, Chautauqua, Cortland, Erie, Genesee, Greene, Hamilton, Lewis, Livingston, Montgomery, NYC- Bronx, NYC- Kings (Brooklyn), NYC- New York (Manhattan), NYC- Queens, NYC- Richmond (Staten Island), Oneida, Onondaga, Ontario, Orange, Oswego, Otsego, Putnam, Rensselaer, Rockland, Schuyler, St Lawrence, Steuben, Suffolk, Sullivan, Tioga, Tompkins, Ulster, Warren, Wayne, and Westchester. Geometry accuracy varies by contributing county. This map service is available to the public.

This layer provides information on municipal, county, and state boundary monuments located throughout the Commonwealth of Pennsylvania. For more information on this layer, you can use the Data Dictionary available in Spreadsheet format. This layer is for use in PennDOT's Open Data Portal. PennDOT is actively updating and maintaining this spatial data. The following sources were used to digitize geometry and populate attributes: USGS Historical Topographic Maps – provided by USGS and ESRI was used as a primary source in geolocating boundary monument points throughout the Commonwealth. Municipal, County, and State boundary monuments are symbolized distinctly within historical USGS Topographic maps. https://www.waymarking.com – provided secondary source information for locating boundary monument point locations, photos, and information. The site is utilized primarily by volunteers and hobbyists who geolocate and catalog physical constructs such as boundary monuments.Google Maps and Google Earth were used to locate boundary monuments and for image acquisition with street view.And with the help of additional DOT departments and agencies such as:Franklin County GIS, Potter County, Tioga County, RETTEW, Professional Survey Societies of NY and PA, Wetmore Surveying, JMT, West Virginia Surveyors Historical Society, National Geodetic SurveyQuestions, comments, or corrections – please contact: Mark Leitzell - mleitzell@pa.govWilliam Havrilchak - wihavrilch@pa.gov
