# NYC Tenants Rights & Community Organization Service Area Boundaries
Polygon boundaries representing estimates of service / catchment areas of tenants rights and community organizations in NYC that operate at the neighborhood level.
Please get in touch if you have organizations to add to this dataset, suggestions, or corrections to be made!
Data is available in GeoJSON and ESRI Shapefile format.
## Data Sources:
This dataset was created from a list of tenants rights organizations I compiled for NYC which includes orgs listed in the [DHCR Community Based Housing Organizations list](https://github.com/clhenrick/DHCR_Community_Based_Housing_Orgs).
The polygon boundaries are sourced from multiple datasources for NYC neighborhoods, zipcode tabulation areas, community district boundaries, as well as boundaries I drew from scratch. For organizations that serve multiple neighborhoods the polygons were dissolved / joined.
- [Pediacities NYC Neighborhoods](http://nyc.pediacities.com/New_York_City_Neighborhoods)
- [NYC Planning Neighborhood Tabulation Areas](http://www.nyc.gov/html/dcp/html/bytes/dwn_nynta.shtml)
- [NYC Zipcode Tabulation Areas](http://catalog.opendata.city/dataset/nyc-zip-code-tabulation-areas)
- [NYC Community District boundaries](http://www.nyc.gov/html/dcp/html/bytes/districts_download_metadata.shtml)
## Notes
There is a lot of overlap in the polygon boundaries. Using PostGIS with a "point in polygon" query will return all organizations that overlap for that specific point. This can be done easily with the data hosted in [CartoDB](http://cartodb.com) by opening the dataset and pasting in the following `SQL` code into CartoDB's SQL Panel. Note that the coordinates for a point must be in the order of lon, lat (x, y).
```
SELECT * FROM nyc_tenants_rights_service_areas
WHERE
ST_Intersects(
ST_GeomFromText(
'Point(-73.982557 40.724435)', 4326
),
nyc_tenants_rights_service_areas.the_geom
);
```
Or by using `ST_Contains`:
```
SELECT * FROM nyc_tenants_rights_service_areas
WHERE
ST_Contains(
nyc_tenants_rights_service_areas.the_geom,
ST_GeomFromText(
'Point(-73.917104 40.694827)', 4326
)
);
```
