Road segments within this layer represent centerlines of public and private (not gated) roadways. Road segments define left (_L) and right (_R) side attributes and address ranges along the segment. Additional attribute information may include:The full street name ST_DIR_NAM;the city or zip community [POSTCOMM_L]; The ZIP code POSTCODE_L; The jurisdiction (Incorporated Municipality) the segment is within [INCMUNI_L];The functional classification [F_CLASS] used; (ex: Interstate, Major Collector, Minor Arterial, Local)The route number [RT_NUM] containing a county road or highway number;The road maintenance provider or construction status [ST_OWNER];Fields used in routing [MPH, ONEWAY, _ELEV, _IM] and; the date that the road segment was created [DATE_CREATED] and last edited [DATE_MODIFIED].This information is was originally compiled from orthophotography in 2001 for use in Public Safety e911 response. Today it is used throughout the County and by the public to conduct business and assist in decision making.County and City staff update records daily or as needed (such as through subdivision plan review and approval using georeferenced CAD files provided by land developers). The road centerlines support address geocoding, analysis, routing and mapping.The centerline represents the geographic location on the roadway between both shoulders (physical center), which often, but not always coincides with the center painted line dividing bi-directional travel lanes. Roadway centerline data plays an important role in transportation management and planning, while also being the basis for all other roadway-related data products.This feature service is updated daily from its source ArcGIS Enterprise feature class. Source data within an Enterprise Geodatabase is accessed by County and City of Rock Hill staff through ArcGIS Server and Portal. When edited, business rules are enforced by BCS theAddresser software. York County has an Address Manual used by staff and stakeholders to ensure quality and standards are adhered to during maintenance and use.For additional information about county maintained roadways, review the County Road Inventory data or search for data through One Map. County staff maintain the relationship between streets and the County Road Inventory through the RT_NUM field. The street ownership [ST_OWNER] designation serves as a source to determine the maintenance provider by municipal public works agencies who actively manage the road assets. SCDOT roadways can be confirmed by reviewing data within their lookup application or their source data within our One Map application.Railroads are contained within the streets feature class to enable cross street lookup (geodcoding), a requirement for e911 dispatchers.Street segments outside the county are present for cartographic and Public Safety dispatch of nearest vehicle (routing) purposes. These can be filtered out and removedAddressing data (streets and addresses) are used to update the US Census Bureau Tiger data in support of the decennial census. As of October 2022, the schema of these data are compatible with NG911. Previous schema remains as of January 2023 with intent to remove fields tentatively planned for 2024. Review the schema field mapping document (PDF) to gain a better understanding of field mapping used to transition these data to NG911 standards. Continuing NG911 compliance projects include splitting the centerline as they cross the city limit.

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.

Adjacent county boundaries originally sourced from Esri data in the 2000s, but have been modified over time to best available data. Municipal boundaries are updated by York County staff when notified of annexations. Municipal boundaries may differ from parcel town tax code until CAMA records are updated.The county boundary may not yet reflect a surveyed boundary, the surveyed county boundary can be found here.This layer is maintained to be coincident with parcel and ORI (Police, Fire, EMS) boundaries. It is often used in court cases to resolve disputes over jurisdiction. As of February 2022, we have identified right of way discrepancies and need to review annexations for the last 5 to 20 years to ensure this layer reflects the intent of the documentation as approved by town councils.Access the file geodatabase source data in SC State Plane coordinate system
This data represents the graphic portrayal of land parcels and their spatial relationships throughout York County, South Carolina. Land parcel boundaries are also the basis for and define coincident boundaries for other layers, such as zoning, subdivisions, public safety response (ORI -Police, Fire, EMS) and Jurisdiction.Boundaries are established from a variety of sources including cadastral plats, subdivision plats, deeds, land contracts, right-of-way plats, and others. Each feature represents a parcel of land that is inventoried by a unique identifier, referred to as a “Tax Map Id” number. This dataset also includes multi-unit structures which have separate tax accounts for each unit, such as condominium units, represented as stacked polygon features. The parent parcel number [ParentTaxID] for the land parcel is distinguished from the child parcel [TaxMapID] for the condo unit. This data does not include mobile home data. Attributes include data stored within the Esri Fabric data model combined with those from the CAMA data. Examples of relevant attributes include:the [TaxMapID], [ParcelID] and [AprAccNum] can be used to uniquely identify each parcel. the [MailAddr1], [MailAddr2], [MailApt], [MailCity], [MailState], [MailZip] can be used as the full tax billing address for the owner.The [Owner1], [Owner2], [Owner3] describe the owner.the [YearBuilt] offers the oldest year a building was built on the property, reference this web map for info on potential lead pipes on premises;the area of the parcel in acres [GISSizeAC] as calculated from the parcel geometry and also the [deededAcres] from recorded documents, and ;the date that the parcel boundary was last edited [DATE_MODIFIED].How were parcels compiled? This layer was initially developed as an ink-on-mylar property maps maintained by the County from the early 1970's through around 2001.In the 1990s, the county procured services to convert parcels from source documents, however the product delivered in 2000 used a methodology which lost fidelity of source documents. Since then, county staff adhered to this same methodology in their daily work. Between 2001 and 2015 staff used an Esri topology to maintain parcel data in ArcMap. In 2015 the county migrated to Parcel Fabric (ArcMap) and then in 2021 to Pro (2.6/10.8.1 Enterprise) Parcel Fabric. In May of 2021 the county began outsourcing maintenance of parcel edits. This has worked well and was initiated in part to ensure a higher standard of editing practice was adhered to, but also to fulfil a shortage of skilled staff in the job market. County parcel mapping staff remain responsible for simple transactions (merge, split), compilation of materials to create vendor edit request task, and QC or review of vendor work. In Q4 2021, County Staff performed a needs assessment to review alignment issues between parcels and other layers and the internal business requirements for data alignment to parcels. They determined boundary layers must remain coincident with parcels, which are used in decision making by citizens and across many areas of government. Also, it was determined that our parcels had many errors from 20 years of edits in a non-Fabric data model and the previous editing practices. The county will be remapping parcels using ARP grant funding in the 2023-2024 timeframe. Upon delivery in 2024, data maintenance practices will ensure ongoing alignment with parcels.Year BuiltTo obtain the year built for structures on a property, use the 'Buildings' table available through our open data portal.Once you have downloaded the 'Buildings' table and this parcels layer, consider processing the building records in some way to join or perform a relate as there could be many buildings on one parcel, using the following fields:Parcel.AprAccNum = BuildingTable.PropertyID(Note: 98,227 parcels have 1 building, 647 parcels have 2 buildings, 272 have 3 or more)Data SchemaReview the Parcel schema document (PDF) to gain a better understand of the data fields.

The National Flood Hazard Layer (NFHL) is a geospatial database that contains current effective flood hazard data. FEMA provides the flood hazard data to support the National Flood Insurance Program. You can use the information to better understand your level of flood risk and type of flooding.The NFHL is made from effective flood maps and Letters of Map Change (LOMC) delivered to communities. NFHL digital data covers over 90 percent of the U.S. population. New and revised data is being added continuously. If you need information for areas not covered by the NFHL data, there may be other FEMA products which provide coverage for those areas.In the NFHL Viewer, you can use the address search or map navigation to locate an area of interest and the NFHL Print Tool to download and print a full Flood Insurance Rate Map (FIRM) or FIRMette (a smaller, printable version of a FIRM) where modernized data exists. Technical GIS users can also utilize a series of dedicated GIS web services that allow the NFHL database to be incorporated into websites and GIS applications. For more information on available services, go to the NFHL GIS Services User Guide.You can also use the address search on the FEMA Flood Map Service Center (MSC) to view the NFHL data or download a FIRMette. Using the “Search All Products” on the MSC, you can download the NFHL data for a County or State in a GIS file format. This data can be used in most GIS applications to perform spatial analyses and for integration into custom maps and reports. To do so, you will need GIS or mapping software that can read data in shapefile format.FEMA also offers a download of a KMZ (keyhole markup file zipped) file, which overlays the data in Google Earth™. For more information on using the data in Google Earth™, please see Using the National Flood Hazard Layer Web Map Service (WMS) in Google Earth™.
NYS Building Footprints - metadata info:The New York State building footprints service contains building footprints with address information. The footprints have address point information folded in from the Streets and Address Matching (SAM - https://gis.ny.gov/streets/) address point file. The building footprints have a field called “Address Range”, this field shows (where available) either a single address or an address range, depending on the address points that fall within the footprint. Ex: 3860 Atlantic Avenue or Ex: 32 - 34 Wheatfield Circle Building footprints in New York State are from four different sources: Microsoft, Open Data, New York State Energy Research and Development Authority (NYSERDA), and Geospatial Services. The majority of the footprints are from NYSERDA, except in NYC where the primary source was Open Data. Microsoft footprints were added where the other 2 sources were missing polygons. Field Descriptions: NYSGeo Source : tells the end user if the source is NYSERDA, Microsoft, NYC Open Data, and could expand from here in the futureAddress Point Count: the number of address points that fall within that building footprintAddress Range : If an address point falls within a footprint it lists the range of those address points. Ex: if a building is on a corner of South Pearl and Beaver Street, 40 points fall on the building, and 35 are South Pearl Street it would give the range of addresses for South Pearl. We also removed sub addresses from this range, primarily apartment related. For example, in above example, it would not list 30 South Pearl, Apartment 5A, it would list 30 South Pearl.Most Common Street : the street name of the largest number of address points. In the above example, it would list “South Pearl” as the most common street since the majority of address points list it as the street. Other Streets: the list of other streets that fall within the building footprint, if any. In the above example, “Beaver Street” would be listed since address points for Beaver Street fall on the footprint but are not in the majority.County Name : County name populated from CIESINs. If not populated from CIESINs, identified by the GSMunicipality Name : Municipality name populated from CIESINs. If not populated from CIESINs, identified by the GSSource: Source where the data came from. If NYSGeo Source = NYSERDA, the data would typically list orthoimagery, LIDAR, county data, etc.Source ID: if NYSGeo Source = NYSERDA, Source ID would typically list an orthoimage or LIDAR tileSource Date: Date the footprint was created. If the source image was from 2016 orthoimagery, 2016 would be the Source Date. Description of each footprint source:NYSERDA Building footprints that were created as part of the New York State Flood Impact Decision Support Systems https://fidss.ciesin.columbia.edu/home Footprints vary in age from county to county.Microsoft Building Footprints released 6/28/2018 - vintage unknown/varies.

This GIS map of New York State displays election districts and polling places across the state as of 6/12/2025. This information is provided by individual counties to the state and reflects the most current data available. The polling place data is currently reflected for counties with a primary election in the June 24, 2025 election. However, a polling place listed on this page does not indicate an election for the respective jurisdiction and polling places are subject to change. Voters are encouraged to verify whether they have a primary election to vote in and their polling locations by using the NYS Board of Elections Poll Site Lookup tool for the most accurate and up-to-date information. https://voterlookup.elections.ny.gov/The polling sites (voting locations) are provided as early voting locations (one dataset for NYC and one for the rest of the state (Non NYC)) and election day voting locations (one NYC and one Non NYC). These are based on data collected by the NYS Board of Elections (https://elections.ny.gov/).The election districts dataset is a combination of data from the NYC and County boards of elections. Information and formatting varied with the source; some variation is still present in this data service. Spatially, the districts may not align with districts from neighboring counties or with other reference datasets such as civil boundaries.
