2008 NOAA Integrated Ocean and Coastal Mapping (IOCM) LIDAR: New Hampshire

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

Sensing Division using an OPTECH ALTM system on June 8, 2008. The data includes topographic data in an LAS format file.

The NOAA Office for Coastal Management (OCM) processed the data to bare earth (class 2) and water points classified (class 9).

An automated filter was used, followed by semi-manual classification and bridge removal.

This lidar was acquired by the NOAA Remote Sensing Division to support NOAA's IOCM (Integrated Ocean and Coastal Mapping)

initiative. 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 (first, second, third, and last) "Outliers" or "false returns"

(e.g., returns from birds, atmospheric particles, and/or system noise) may be present in the data.

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this data may no longer represent actual surface conditions.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 +/- 2.0m.

; Quantitative Value: 2.0 meters, Test that produced the value: 2 Sigma

The data positions were obtained using post processed KGPS methods. The RMSE = 13.0 cm in open terrain based on

10 points.
