Description: DCP Mapping Lots includes features that are not on the Tax Map. They have been added and maintained by DCP for cartographic purpose. There are three kinds of Mapping Lots: street center 'malls' which are small road-divider type blocks separating lanes of traffic on certain streets; Traffic islands which are small traffic lane separators or pedestrian rest stop blocks other than malls (usually at intersections); streets through parks which are streets existing physically in parks but are not part of the Tax Map.

Description: As part of the Framework, the extent of coastal flood hazard was completed by using readily availableSea, Lake, and Overland Surge from Hurricanes (SLOSH) modeling conductedby NOAA. SLOSH modeling of hurricane intensities is categorized by the Saffir-Simpson hurricane wind scale and includes other characteristics of hurricanes that can vary considerably along the coast, such as angle of approach to the shoreline, width and slope of the continental shelf, astronomical high tide level, and local geographic features (FEMA 2011). The SLOSH model outputs inform hurricane evacuation studies. The inundation zones identified by the SLOSH model depict areas of possible flooding from the maximum of maximum (MOM) event within the five categories of hurricanes by estimating the potential surge inundation during a high-tide landfall. Although the SLOSH inundation mapping is not referenced to a specific probability of occurrence (unlike FEMA flood mapping, which presents the 0.2-percent- and 1-percent-annual-chance flood elevation zones) nor does it include wave heights, the flooding inundation from a Category 4 hurricane making landfall during high tide represents an extremely lowprobability of occurrence but high-magnitude event.The intent of the NACCS is to generate a spatially comprehensive, but first-order approximation of flooding vulnerability across the entire northeastern Atlantic coastal region. The use of the SLOSH model MOM was necessary based on the very large spatial extent of the study area and the fact that it is currently the most advanced storm surge modeling available for the entire study area. The extent of the Category 4 MOM represents the maximum storm tide levels caused by extreme hurricane scenarios across the region, and, therefore, provides a reasonable approximation of the most extreme flooding extent. The State and District of Columbia Appendix presents the SLOSH hydrodynamic modeling inundation mapping associated with Categories 1 through 4 hurricanes used for evacuation modeling.
Description: Digital planimetrics are derived using the products delivered with the 2010 New York Statewide Flyover, which includes raw imagery collected to support the generation of 0.5 Ft Ground Sample Distance (GSD) natural color imagery. The images were captured with 80% forward lap and side lap to support 1”=100’ mapping and meet the distortion free requirements within New York City. Planimetrics are developed to meet American Society for Photogrammetry and Remote Sensing (ASPRS) Class 1 (one) horizontal mapping standards and ASPRS vertical Class 2 (two) accuracy specifications. Planimetrics are delivered via an ESRI geodatabase in New York State Plane Coordinates, Long Island East Zone, NAD83, US foot.

Description: Point features representing the geographic locations of facilities, programs or parkland properties in New York City contained in the master table in an Access database which was developed with the cooperation and assistance of numerous governmental and non-profit agencies. Users can access the location, type, capacity and oversight agency of public and private educational, recreational, cultural, public safety, criminal justice, health, mental health, chemical dependency, developmental disabilities, day care, foster care, senior citizen, homeless facilities and programs. Data related to the location of transportation and waste management facilities have also been included. These facilities and programs are, with few exceptions, operated, funded, licensed, or certified by a government agency. Each facility or program site is geocoded for tax block, tax lot, 2010 census tract, city council district, community district, school district, police precinct, health area, zip code, borough, and x and y coordinates, provided by the Department of City Planning's Geosupport Information System (GIS). Parkland properties are coded for borough, community district, tax block, taxt lot, and x and y coordinates only. The features in the shapefile are represented by points created with ArcGIS tool using the x and y coordinates mostly derived from the centroids of the tax lots where facilities, programs or parkland properties are located.

Description: 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 techniques (OBIA) 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%.
