Click on this link and take a look at the brief video tutorial there. It walks users though the basic functionality of the NYC Crime Map and should be a big help for first time visitors to the site, and even for seasoned users who may have missed something.
In February we released a major enhancement to NYCityMap, the single field search.
With this new input field NYCityMap now supports more search types and formats than ever before. Some of them might not be obvious so we thought we’d provide you with this (no longer) missing manual.
The following types of locations are accepted by the single field search:
- Borough/Block/Lot (BBL)
- ZIP Code
- Community District
- City Council District
- Street between intersections
- Place of Interest
Each property in New York City is identified by a set of 3 numbers called the Borough, Block, and Lot (BBL). BBLs are used by many city agencies to identify real estate for taxes, zoning, construction, and other purposes.
The Borough number is always first:
1 = Manhattan
2 = Bronx
3 = Brooklyn
4 = Queens
5 = Staten Island
The Block number is second and can be up to 5 digits.
The Lot number is last and can be up to 4 digits.
An example, the BBL of City Hall is 1001220001.
When it comes to searching for a BBL in the new single field search, several formats are accepted:
- MANHATTAN 122 1
- 1 122 1
- manhattan block:122 lot:1
There are two formats of ZIP Code that are accepted, the typical 5-digit ZIP or the extended ZIP+4 format. Here are some examples:
There are 59 community districts in NYC. You can search for them using several formats:
- Community District 101
- 84 Queens
- Community District: 3 Staten Island
- 3 Staten Island
- Staten Island 3
- Bronx Community Board 12
- Board 101
- Board 1 Manhattan
- Board Manhattan 1
City Council District
The New York City Council is the law-making body of the City of New York. It is comprised of 51 members from 51 different Council Districts throughout the five boroughs. You can search for them using several formats:
- city council district 10
- city council district: 10
In order to see the boundary of a particular borough in NYCityMap, you can search by borough name. Several abbreviated formats are accepted. Here are the acceptable values by borough:
- the bronx
- Staten Island
For 4 of the 5 boroughs, the borough is equivalent to the city (Manhattan = New York). However Queens is made up of 44 different cities. City is a searchable type in NYCityMap. Here are some examples:
- Rego Park
- East Elmhurst
New York City’s neighborhoods are constantly changing and for that reason hard to pin down geographically. But we know that we have many NYC visitors who use NYCityMap and may want to get a general idea of the vicinity of a neighborhood. For that reason we have added a neighborhood search type. Searching for a neighborhood name will take you to roughly the center of the requested neighborhood. There are 296 neighborhoods available in NYCityMap, here are a few:
- Battery Park
- Brooklyn Heights
- East Harlem
- East Village
Street between intersections
If you want to search for a block you can do a street between intersections search, also known as a blockface. This is a segment of a street bordered by two intersections. Take the example shown in the image below, Broadway between Park Place and Barclay Street in Manhattan:
This blockface can be entered into the single field search in several formats:
- Broadway between Park Place and Barclay Street, MN
- Broadway between Park Place & Barclay Street, MN
- Broadway bw Park Place and Barclay Street, Manhattan
- Broadway b/w Park Place and Barclay Street, 10007
- Broadway btwn Park Place and Barclay Street Manhattan
- Broadway btwn. Park Place and Barclay Street MN
An intersection is the meeting of any two streets. Like a blockface search several formats are accepted and they can be extrapolated as:
<Cross Street> <and> <Cross Street> <Borough>
- Broadway and Park Place, Manhattan
- Broadway @ Park Place, 10007
- Broadway at Park Place, MN
- Broadway & Park Place, New York
You can search for coordinates in latitude and longitude or NY State Plane. As with other searches, several formats are accepted:
- <x> <y>
- <x> / <y>
- <x>, <y>
- x:<x> y:<y>
- x=<x> y=<y>
- <longitude> <latitude>
- <longitude> / <latitude>
- <longitude>, <latitude>
- lon: <longitude> lat: <latitude>
- lon=<longitude> lat=<latitude>
- long: <longitude> lat: <latitude>
- long=<longitude> lat=<latitude>
- 982574, 198961 (City Hall, Manhattan)
- -73.9858 / 40.7485 (Empire State Building, Manhattan)
Buildings in NYC have a unique Building Identification Number (BIN). This 7-digit number number is assigned by the Department of City Planning. Most users will not be familiar with the BIN number they are looking for, if you would like to find a BIN number you can use the Department of Buildings Buildings Information Search application, but most users will search by address instead.
For example, the BIN number for 52 Chambers Street in Manhattan is 1079146.
Place of Interest
Major sites within New York City can be searched as a place of interest without having to know the specific address. Even including a borough on this search is optional. Here are some examples:
- Statue of Liberty
- Empire State Building
- Empire State Building, MN
- Yankee Stadium
- Citi Field
Last, but certainly not least, we have the address search. For the address search there are too numerous formats accepted to list them all. There are however only 3 components that your address search must include: house number, street, and borough. Borough can be indicated by borough name, borough abbreviation, ZIP code, or city. You may in some cases provide more information than this in your search input, and that is okay, but the extra info will be ignored. Here are some examples, all of them result in the same address search for 52 Chambers Street in Manhattan.
- 52 Chambers Street MN
- 52 Chambers Street 10007
- 52 Chambers Street Manhattan
- 52 Chambers Street, New York
- 52 Chambers Street, New York, NY 10007
- 52 Chambers St, MN

The process of using an address or intersection to get geographic coordinates for the purpose of mapping a location is known as geocoding. NYCityMap relies on the Department of City Planning’s mainframe-based Geosupport system (Geosupport was developed specifically for New York City in the 1980’s and has evolved over time to handle the many NYC addressing anomalies including Queens hypenated address – well before others could, out-of-sequence addressing and Edgewater Park.) for basic geocoding functionality.
There are different methods that can be employed for geocoding an address. One approach, often called fall-back or cascade geocoding, attempts to find a match using the highest degree of precision and moves to lower precision methods until a match is found (if one exists). NYCityMap employs a fall-back approach using Geosupport for the individual geocoding requests (i.e., passes) and then queries the spatial data to render the results on a map. This results in different types of maps being rendered after submitting an address search.
The first pass tries to match an input address against the actual address(es) associated with a tax parcel or building. The unique identifiers for these features are returned as part of a successful geocode. These identifiers are then used to query the database to find a match and render the results on the map. If a building match is found, the building is highlighted in the resulting map (see example below) and building-level information is available.
If a building is not found but a tax parcel is (pass two), a star representing the center of the tax parcel is placed in the resulting map (see example below).
The second pass attempts to match the address against the theoretical range of addresses along a block (a street between two cross streets). This method interpolates between the highest and lowest addresses for each side of the street. For example, Maiden lane between Nassau and William Streets has the following address rages:
- North side of the street; low = 28 and high = 62
- South side of the street; low = 29 and high = 65 and 1 Federal Reserve Plaza
Ever wondered who represents you at the local, state and federal level? Your representatives are determined by where you live. We’ll steer clear of the political redistricting discussion and focus on the topic. To find out, you can search NYCityMap. From an address search, click “Show Additional Information…” as shown below.
At the bottom of the subsequent panel, click “Elected Official Information” as shown below. There are tabs across the panel for viewing Local, State and Federal elected officials. Additionally, there is a vertical scroll bar along the right side to navigate the content.
If you find any errors, click “Feedback Form” at the top of the page and let us know.
Even after using NYCityMap once, we hope it becomes clear that a wealth of information is displayed in the application. The basemap (i.e., primary map data excluding dynamic layers) alone is particularly complex and replete. One of the original design goals for NYCityMap was to keep the cartographic symbology simple and self-explanatory. In the event that this goal has not be achieved and to provide a visual reference, the following sample map is provided. This visual explanation, or legend, shows the symbols presented on the basemap.
As you can see, there certainly is no dearth of data in NYCityMap!
NYCityMap provides the ability to view aerial photography from multiple years as well as viewing a cartographic map. To view a particular aerial or to toggle back to viewing the map, click on the Show Aerial Photo Map icon and then click on the aerial year of choice or Map in the slidebar to return to the cartographic map.
