A 6-in resolution 8-class land cover dataset derived from the 2017 Light Detection and Ranging (LiDAR) data capture. This dataset was developed as part of an updated urban tree canopy assessment and therefore represents a ''top-down" mapping perspective in which tree canopy overhanging features is assigned to the tree canopy class. The eight land cover classes mapped were: (1) Tree Canopy, (2) Grass\Shrubs, (3) Bare Soil, (4) Water, (5) Buildings, (6) Roads, (7) Other Impervious, and (8) Railroads. The primary sources used to derive this land cover layer were 2017 LiDAR (1-ft post spacing) and 2016 4-band orthoimagery (0.5-ft resolution). Object based image analysis was used to automate land-cover features using LiDAR point clouds and derivatives, orthoimagery, and vector GIS datasets --

For the purposes of classification, only vegetation > 8 ft were classed as Tree Canopy. Vegetation below 8 ft was classed as Grass/Shrub.

This dataset contains information for buildings that have completed the certification process. These buildings are all publicly viewable on the WiredNYC website (www.wiredscore.com)

This dataset is part of the DOB NOW Electrical Permit Data Collection: https://data.cityofnewyork.us/browse?Data-Collection_Data-Collection=DOB+NOW+Electrical+Permits+Data
This dataset contains details of the electrical scope of work. For each Job Filing Number, there can be multiple rows/records in this dataset. For example, there might be electrical work being performed in the basement as well as on the 4th floor. One row/record for Basement and one for the floor. The job might have some 101 to 200 amps Service Switches as well as some Up to 100 amps Service Switches, and there would be one row/record for each.

The NYC 3D Model by Community District is a publicly available model consisting of every building in New York City present in 2014. The model is based on DOITT’s 2014 aerial survey, which provides roof structure details, including a high-level of detail for certain iconic buildings. The Department of City Planning imported and enhanced the DOITT files by converting the entire model into .3dm format, which is compatible with Rhinoceros 3D modeling software. DCP also divided the model into the City’s 59 Community Districts and enriched each CD with base layers, including lots, streets, parks, and rail lines.
The 3D model is capable of being imported into most common 3D-modeling software, including Sketchup and AutoCAD.

Condominiums and cooperatives are valued as if they were residential rental apartments. Income information from similar rental properties is applied to determine value.
The Department of Finance (DOF) chooses similar properties to value condos and coops. Properties are selected based on a combination of factors such as: land location, income levels, building age and construction and exemptions and subsidies.

This dataset contains building information for all buildings that have completed a WiredNYC survey. This includes buildings that have opted-out from displaying their profiles publicly. Therefore, the building-specific data (e.g. building address) provided is anonymous and only linked to the borough the building is located in.

Contains all occupied and vacant facilities portfolio from Facility Planning (commercial spaces) and Community Operations (community centers, senior centers, day care centers, health centers, etc) It includes the 5 Community Operations borough offices. The source data is our latest Property Directory as December 2012. The field “Comments” contains summary codes to distinguish the type of facility (BO – NYCHA Community Operations Borough Offices, CO – Community Operations, FP – Facility Planning). Please note that there are two commercial spaces (not coded under field “comments”)recorded in our property directory which are not part of the portfolio for Facility Planning.

High resolution land cover data set for New York City. This is the 3ft version of the high-resolution land cover dataset for New York City. Seven land cover classes were mapped: (1) tree canopy, (2) grass/shrub, (3) bare earth, (4) water, (5) buildings, (6) roads, and (7) other paved surfaces. The minimum mapping unit for the delineation of features was set at 3 square feet. The primary sources used to derive this land cover layer were the 2010 LiDAR and the 2008 4-band orthoimagery. Ancillary data sources included GIS data (city boundary, building footprints, water, parking lots, roads, railroads, railroad structures, ballfields) provided by New York City (all ancillary datasets except railroads); UVM Spatial Analysis Laboratory manually created railroad polygons from manual interpretation of 2008 4-band orthoimagery. The tree canopy class was considered current as of 2010; the remaining land-cover classes were considered current as of 2008. Object-Based Image Analysis (OBIA) techniques were employed to extract land cover information using the best available remotely sensed and vector GIS datasets. OBIA systems work by grouping pixels into meaningful objects based on their spectral and spatial properties, while taking into account boundaries imposed by existing vector datasets. Within the OBIA environment a rule-based expert system was designed to effectively mimic the process of manual image analysis by incorporating the elements of image interpretation (color/tone, texture, pattern, location, size, and shape) into the classification process. A series of morphological procedures were employed to insure that the end product is both accurate and cartographically pleasing. More than 35,000 corrections were made to the classification. Overall accuracy was 96%. This dataset was developed as part of the Urban Tree Canopy (UTC) Assessment for New York City. As such, it represents a 'top down' mapping perspective in which tree canopy over hanging other features is assigned to the tree canopy class. At the time of its creation this dataset represents the most detailed and accurate land cover dataset for the area. This project was funded by National Urban and Community Forestry Advisory Council (NUCFAC) and the National Science Fundation (NSF), although it is not specifically endorsed by either agency. The methods used were developed by the University of Vermont Spatial Analysis Laboratory, in collaboration with the New York City Urban Field Station, with funding from the USDA Forest Service.

This report includes information at a condominium suffix level which represents a subdivision of the condominium since DOF values condominiums at a suffix level. A condominium may have more than one suffix.

Each record in this report for the subject condominium represents a condominium suffix which is a subdivision of a condominium. Some condominiums may have more than a single suffix. DOF uses this information to value condominiums annually based on state law. Each suffix identifies up to three comparable rentals included in this report.
