2013 NOAA NGS LIDAR of New Jersey: Barnegat Light

These data were collected by the National Oceanic Atmospheric Administration National Geodetic Survey Remote Sensing Division using

a Riegl VQ820G system. The data is for Barnegat Light, New Jersey, in Ocean County. The data were acquired from 20130923 - 20130924.

The data includes topobathy data in an LAS 1.2 format file classified as: unclassified (1), ground (2), noise (7), high point (21),

bathymetric point (26), bathy noise (27). For Digital Coast storage purposes, NOAA OCM reclassified the following classes: 21 (high points)

reclassed to 7 (low point, noise), 26 (bathymetric point) reclassed to 11 (NOAA OCM bathymetric lidar point), 27 (bathy noise) reclassed to 9 (water).

Therefore, the classes of data available from the NOAA Digital Coast are:

1 Unclassified

2 Ground

7 Noise

9 Water

11 Bathymetric lidar

This data set also includes lidar intensity values and encoded RGB image values.

This lidar data are an ancillary product of NOAA's Coastal Mapping Program (CMP), created through a wider Integrated Ocean and Coastal Mapping

initiative to increase support for multiple uses of the data. It is not intended for mapping, charting, or navigation. In addition, it will

be used for ongoing research efforts for testing and developing standards for airborne lidar.

Data include all lidar returns. Outliers or false returns (e.g., returns from birds, atmospheric particles, and/or system noise) may be present

in the data. An automated ground classification algorithm was used to determine bare earth point classification. It should be noted that not

all returns were correctly classified; therefore the user should examine for acceptability.

Users should be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual

surface conditions. Users should not use this data for critical applications without a full awareness of its limitations.

OS Independent

The data positions were obtained using post processed KGPS methods. The horizontal accuracy of the data is better than plus or minus 1.0 m.; Quantitative Value: 1.0 meters, Test that produced the value: 2 Sigma

The data positions were obtained using post processed KGPS methods. The vertical accuracy of the data is better than plus or minus 0.15 m.; Quantitative Value: 0.15 meters, Test that produced the value: 2 Sigma
