Publication Date: April 2025. Updated annually, or as needed. The data can be downloaded here: https://gis.ny.gov/parcels#data-download. This feature service only contains parcel data for NYS State-owned tax parcels. 2024 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 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. The State-owned tax parcel polygons in this file are the result of a best effort selection based on the Primary Owner and Additional Owner fields in the NYS Statewide Tax Parcels file, Geospatial Services data, State agency data, and online research. These same data and information are also the basis for a best effort assignment of a NYS agency name (listed in the NYS Name field) to most tax parcel polygons where the Owner Type field value is State. The NYS Name Source field consists of a code that describes how the State-owned designation and agency name were determined, if this was verified, and the means of verification, if applicable.This map service is available to the public.The State of New York, acting through the New York State Office of Information Technology Services, makes no representations or warranties, express or implied, with respect to the use of or reliance on the Data provided.

Publication Date: April 2025. This polygon layer is updated annually.

This layer contains 2024 parcel data only for NY State counties which gave NYS ITs Geospatatial 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 the Geospatial Services permission to share their parcel data with the public. Parcel data for counties which do not allow the 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.

Please note: this data is updated as of 2023.Overview of the Data:The operational purpose of the tax parcel data set is to facilitate the calculation and collection of property taxes. Each publicly or privately owned property in the city of Rochester has an official tax parcel record. This feature layer shows the polygon boundaries for each of the over 65,000 tax parcels in the city, along with several fields from their parcel records that detail information about the property, including ownership, property type, and assessed values. How does the tax map system work in New York State? What does Section, Block, Lot refer to?Each county in the state has a tax map that includes all of the parcels in each of its cities, towns, and villages. The county tax map is subdivided into sections of even, modular units that are 8,000 feet by 12,000 feet. Each of these sections are then subdivided into blocks of up to 100 parcels. Blocks are typically formed by following natural boundaries (i.e., roads, rivers, railroad tracks). Lot numbers are assigned to each parcel in a block following a set pattern according to their location on the map. Each parcel is thus assigned a Section, Block, Lot (SBL) number for identification and tax administration purposes. For more information on this identification system, please see the General Guide for Tax Mapping in New York State, put out by the Property Tax Assessment Administration.Related Resources:For a searchable interactive mapping application, please visit the City of Rochester's Property Information explorer tool.

**ATTENTION USERS - This downloadable file will be retired by October 2025 ** The Digital Tax Map has been republished on Open Data as a growing collection of its map layers and data tables. You can find the collection here with the latest information: Digital Tax Map Collection. • Updates: Data is extracted from DOF’s internal system on the last Friday of each month and refreshed on ArcGIS Online on the 1st. The online map always shows the most recent version. • Accessing the Data: • Digital Tax Map on NYC Open Data: See the complete collection. • Individual layers: Downloadable from the Digital Tax Map Feature Server. • Complete source: Available through the Digital Tax Map service, which always points to the latest monthly release. Note: To ensure reliability, the Tax Map alternates between Set A and Set B each month. If one set has issues, the previous month’s copy remains online. Both sets are kept about a month apart and are available for download: • Set A link • Set B link • Digital Alteration Book (DAB): The DAB is the official log of map changes—such as new lots, merges, or boundary shifts—providing a clear record of how the Tax Map evolves. It is available through the Property Information Portal. Coming soon the collection on Open Data will grow to include information from the Digital Alteration Book (DAB) that will keep track of historical changes to the Digital Tax Map. Disclaimer: This dataset reflects formal applications submitted to DOF but may not reflect the latest changes in other City systems (e.g., exemptions or buildings data). It is provided for informational purposes only and is not guaranteed to be accurate as of today’s date.

This is a vector file that represents tax parcels boundaries in Monroe County, New York. According to § 102. Definitions (of the Real Property Tax Law of New York State):"Parcel" means a separately assessed lot, parcel, piece or portion of real property, except publicly owned bridges and land used for street, road, highway or parkway purposes. A parcel shall not be bisected by a municipal corporation boundary line except that in a special assessing unit a parcel may be bisected by a school district or village boundary line. For more information on parcels, see the "Parcel" feature class in the RPS_Parcels feature dataset that is maintained by the Monroe County Real Property Services (RPS) department from which this layer was created. The difference between this parcel feature class and the RPS parcel feature class is the latter is updated daily by RPS staff by digitizing new parcel features and does not contain assessment roll data. This layer is recreated biannually by DES staff by joining RPS parcels with the same assessment roll data used to create the Base_County_Parcel_Centroids feature class.

Publication Date: April 2025. This polygon layer is updated as needed and is current as of the publication date.

This layer is intended to be used in conjunction with the NYS_Tax_Parcels_Public layer (which only displays when zoomed in below 1:37,051-scale). NYS_Tax_Parcels_Public_Footprint only displays when zoomed out beyond 1:37,050-scale. It contains labeled polygons only for those counties which make their tax parcel GIS data publicly available and are in the NYS_Tax_Parcels_Public layer.

Boundaries were digitized at 1:24,000-scale.

Overview of the Data:The operational purpose of the tax parcel data set is to facilitate the calculation and collection of property taxes. Each publicly or privately owned property in the city of Rochester has an official tax parcel record. The assessed value of every tax parcel in the city is recalculated based on recent sales and professional appraisals every four years. Reassessment years provide the best snapshot period for historical comparison, and included on the open data portal are 1996, 2000, 2004, 2008, 2012, 2016, and 2020. This feature layer shows the polygon boundaries for each of the over 65,000 tax parcels in the city, along with several fields from their parcel records that detail information about the property, including ownership, property type, and assessed values.

The objective of this data collection was to examine inequalities of wealth and the geographic distribution of wealthy individuals in late 18th- and early 19th-century New York and to investigate wealth in relationship to occupation and location. For this study, the entire set of tax assessment records and United States Census records for New York City were computerized and occupational status was added for all entries. The collection addresses topics such as social class structure, demographic factors, occupational status and geographic distribution, property values and geographic distribution, and the relationship of these factors to the political system. Units of analysis were individual property owners and renters for the tax assessment data and heads of households for the census data. Data collected included the individual's name, address, occupation, sex, and race, the type, quantity, and value of real and personal property, and the type and occupancy of the structure at the address. Occupational data from city directories were used to supplement the tax and census data.

Summary:

The files contained herein represent green roof footprints in NYC visible in 2016 high-resolution orthoimagery of NYC (described at https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_AerialImagery.md). Previously documented green roofs were aggregated in 2016 from multiple data sources including from NYC Department of Parks and Recreation and the NYC Department of Environmental Protection, greenroofs.com, and greenhomenyc.org. Footprints of the green roof surfaces were manually digitized based on the 2016 imagery, and a sample of other roof types were digitized to create a set of training data for classification of the imagery. A Mahalanobis distance classifier was employed in Google Earth Engine, and results were manually corrected, removing non-green roofs that were classified and adjusting shape/outlines of the classified green roofs to remove significant errors based on visual inspection with imagery across multiple time points. Ultimately, these initial data represent an estimate of where green roofs existed as of the imagery used, in 2016.

These data are associated with an existing GitHub Repository, https://github.com/tnc-ny-science/NYC_GreenRoofMapping, and as needed and appropriate pending future work, versioned updates will be released here.

Associated Files:

As of this release, the specific files included here are:

• GreenRoofData2016_20180917.geojson is in the human-readable, GeoJSON format, in geographic coordinates (Lat/Long, WGS84; EPSG 4263).
• GreenRoofData2016_20180917.gpkg is in the GeoPackage format, which is an Open Standard readable by most GIS software including Esri products (tested on ArcMap 10.3.1 and multiple versions of QGIS). This dataset is in the New York State Plan Coordinate System (units in feet) for the Long Island Zone, North American Datum 1983, EPSG 2263.
• GreenRoofData2016_20180917_Shapefile.zip is a zipped folder containing a Shapefile and associated files. Please note that some field names were truncated due to limitations of Shapefiles, but columns are in the same order as for other files and in the same order as listed below. This dataset is in the New York State Plan Coordinate System (units in feet) for the Long Island Zone, North American Datum 1983, EPSG 2263.
• GreenRoofData2016_20180917.csv is a comma-separated values file (CSV) with coordinates for centroids for the green roofs stored in the table itself. This allows for easily opening the data in a tool like spreadsheet software (e.g., Microsoft Excel) or a text editor.

Column Information for the datasets:

Some, but not all fields were joined to the green roof footprint data based on building footprint and tax lot data; those datasets are embedded as hyperlinks below.

• fid - Unique identifier
• bin - NYC Building ID Number based on overlap between green roof areas and a building footprint dataset for NYC from August, 2017. (Newer building footprint datasets do not have linkages to the tax lot identifier (bbl), thus this older dataset was used). The most current building footprint dataset should be available at: https://data.cityofnewyork.us/Housing-Development/Building-Footprints/nqwf-w8eh. Associated metadata for fields from that dataset are available at https://github.com/CityOfNewYork/nyc-geo-metadata/blob/master/Metadata/Metadata_BuildingFootprints.md.
• bbl - Boro Block and Lot number as a single string. This field is a tax lot identifier for NYC, which can be tied to the Digital Tax Map (http://gis.nyc.gov/taxmap/map.htm) and PLUTO/MapPLUTO (https://www1.nyc.gov/site/planning/data-maps/open-data/dwn-pluto-mappluto.page). Metadata for fields pulled from PLUTO/MapPLUTO can be found in the PLUTO Data Dictionary found on the aforementioned page. All joins to this bbl were based on MapPLUTO version 18v1.
• gr_area - Total area of the footprint of the green roof as per this data layer, in square feet, calculated using the projected coordinate system (EPSG 2263).
• bldg_area - Total area of the footprint of the associated building, in square feet, calculated using the projected coordinate system (EPSG 2263).
• prop_gr - Proportion of the building covered by green roof according to this layer (gr_area/bldg_area).
• cnstrct_yr - Year the building was constructed, pulled from the Building Footprint data.
• doitt_id - An identifier for the building assigned by the NYC Dept. of Information Technology and Telecommunications, pulled from the Building Footprint Data.
• heightroof - Height of the roof of the associated building, pulled from the Building Footprint Data.
• feat_code - Code describing the type of building, pulled from the Building Footprint Data.
• groundelev - Lowest elevation at the building level, pulled from the Building Footprint Data.
• qa - Flag indicating a positive QA/QC check (using multiple types of imagery); all data in this dataset should have 'Good'
• notes - Any notes about the green roof taken during visual inspection of imagery; for example, it was noted if the green roof appeared to be missing in newer imagery, or if there were parts of the roof for which it was unclear whether there was green roof area or potted plants.
• classified - Flag indicating whether the green roof was detected image classification. (1 for yes, 0 for no)
• digitized - Flag indicating whether the green roof was digitized prior to image classification and used as training data. (1 for yes, 0 for no)
• newlyadded - Flag indicating whether the green roof was detected solely by visual inspection after the image classification and added. (1 for yes, 0 for no)
• original_source - Indication of what the original data source was, whether a specific website, agency such as NYC Dept. of Parks and Recreation (DPR), or NYC Dept. of Environmental Protection (DEP). Multiple sources are separated by a slash.
• address - Address based on MapPLUTO, joined to the dataset based on bbl.
• borough - Borough abbreviation pulled from MapPLUTO.
• ownertype - Owner type field pulled from MapPLUTO.
• zonedist1 - Zoning District 1 type pulled from MapPLUTO.
• spdist1 - Special District 1 pulled from MapPLUTO.
• bbl_fixed - Flag to indicate whether bbl was manually fixed. Since tax lot data may have changed slightly since the release of the building footprint data used in this work, a small percentage of bbl codes had to be manually updated based on overlay between the green roof footprint and the MapPLUTO data, when no join was feasible based on the bbl code from the building footprint data. (1 for yes, 0 for no)

For GreenRoofData2016_20180917.csv there are two additional columns, representing the coordinates of centroids in geographic coordinates (Lat/Long, WGS84; EPSG 4263):

• xcoord - Longitude in decimal degrees.
• ycoord - Latitude in decimal degrees.

NOTE: Use the field SBL20 when linking to other parcel recordsOverview of the Data: The operational purpose of the tax parcel data set is to facilitate the calculation and collection of property taxes. Each publicly or privately owned property in the city of Rochester has an official tax parcel record. The assessed value of every tax parcel in the city is recalculated based on recent sales and professional appraisals every four years. Reassessment years provide the best snapshot period for historical comparison, and included on the open data portal are 1996, 2000, 2004, 2008, 2012, 2016, and 2020. This excel file includes a record for each of the over 65,000 tax parcels with fields that detail information about the property, including ownership, property type, and assessed values. How does the tax map system work in New York State? What does Section, Block, Lot refer to?Each county in the state has a tax map that includes all of the parcels in each of its cities, towns, and villages. The county tax map is subdivided into sections of even, modular units that are 8,000 feet by 12,000 feet. Each of these sections are then subdivided into blocks of up to 100 parcels. Blocks are typically formed by following natural boundaries (i.e., roads, rivers, railroad tracks). Lot numbers are assigned to each parcel in a block following a set pattern according to their location on the map. Each parcel is thus assigned a Section, Block, Lot (SBL) number for identification and tax administration purposes. For more information on this identification system, please see the General Guide for Tax Mapping in New York State, put out by the Property Tax Assessment Administration.Related Resources:For a searchable interactive mapping application, please visit the City of Rochester's Property Information explorer tool.
