Open Address Data

Summary

This data is every standardized address and related coordinates contained in the City of Philadelphia's Unified Land Record System (ULRS).

Features updated: 10/09/2015
Attributes updated: 10/09/2015
Metadata updated: 05/18/2014
Update frequency: This process will be scripted to update the data automatically every week on schedule with the ULRS.

Description

DATA DEVELOPMENT: This data is created from the ULRS PARCEL_ADDRESS table that contains a row of every standardized address in the system and is linked to a parcel. Each row also contains coordinates in NAD_1983_StatePlane_Pennsylvania_South_FIPS_3702_Feet (2272). The uploaded data is exported from the table after a running a SQL query against the layer to make sure none of the following fields are NULL; street_number, street_name, street_type, x_coord, and y_coord.

select DISTINCT (to_char(street_number) || NVL2(to_char(street_number_suffix),' ' || to_char(street_number_suffix), '')) "NUMBER", (NVL2(street_prefix,street_prefix || ' ','') || street_name || ' ' || street_type || NVL2(street_suffix,' ' || street_suffix, '')) STREET, to_char(UNIT), x_coord LON, y_coord LAT from parcel_address
where x_coord is not null and y_coord is not null and street_number is not null and street_name is not null and street_type is not null

This exported csv is loaded into ArcMap and then exported using the City of Philadelphia's arc-open toolbox which exports a shapefile, csv, and geojson file of the data in WGS 84.

COORDINATE SYSTEM: GCS_WGS_1984, WKID: 4326, Decimal Degrees.

THEMATIC MAPPING: Use the LAT and LON fields for thematic mapping and the NUMBER and STREET fields for labeling.
