This geodatabase of milepost locations was developed using the NJ Roadway Network. It shows milepost locations in tenths of a mile
along the state highways in New Jersey. It was developed for use with ESRI’s geographic information systems application.

National Spatial Reference System
Geodetic Survey (NGS) defines and manages the National Spatial
Reference System, which determines position, height, distance, gravity,
and shoreline throughout the United States. The referencing data is
collected via several networks.
Base Network (FBN) is a nationwide network of permanently monumented
stations providing precise spatial reference control. By integrating
horizontal and vertical networks, the FBN enhances the national spatial
framework for precise navigation, mapping, and resource management.

Operating Reference Stations (CORS) are GPS stations that provide
carrier phase and code range measurements for real-time and post-processing
an interactive map of US CORS locations.

New Jersey Roadway Network
The NJ Roadway Network file is the Official LRS for the New Jersey
Department of Transportation. The file is a geodatabase that includes
a linear referencing system that represents the public roadways in
New Jersey. It was developed for use with ESRI’s
geographic information systems applications and was structured to
conform to the UNETRANS
data model. The NJDOT data model reflects some of the key components
of the UNETRANS
model as outlined in the Transportation Data
Models Analysis Report (pdf 2.5m).
The “NJ Roadway Network” is updated every calendar year. The database contains
over 39,000 miles of roadway which includes Interstates, Toll routes,
US routes, State routes, County routes, Local streets and Ramps.
For additional information on the “NJ Roadway Network”, refer to the
metadata that is included with the file.

The United States Geological Survey (USGS) and NJDOT have partnered
to provide the New
Jersey Tide Telemetry System. Links to the New Jersey Tidal and
Streamflow gauges (146 sites) can be found at the
