Count Component Title Abstract
1 2004 ENSR Bare Earth Topographic Lidar: Hampden County, Massachusetts Spectrum Mapping was tasked by ENSR International (now a subsidiary of AECOM Technology Corporation) to collect LIDAR data and digital ortho imagery to generate breaklines and a bare earth DEM to support 2-foot contour intervals in accordance with FEMA Appendix A. The project area for Connecticut River floodplain was approximately 143 square miles in Hampden County, Massachusetts. The Spectrum aircraft was equipped with the RAMS system, including a 26 Khz Laser, an inertial measurement unit (IMU), and a dual frequency GPS receiver and antenna. The RAMS sensor system also includes a RAMS 4K X 4K color digital camera mounted to the LIDAR unit.

        Count Component Use Limitation
        1 Lidar Use Limitation These data depict the elevations at the time of the survey and are only accurate for that time. 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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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. Any conclusions drawn from analysis of this information are not the responsibility of NOAA or any of its partners. These data are NOT to be used for navigational purposes.

        1 2004-01-01T00:00:00 Detailed information about Spectum Mapping's data processing procedures can be found in the Project Report located above in the Supplemental_Information section.
        1 2013-10-01T00:00:00 The NOAA Coastal Services Center (CSC) received topographic files in ASCII .CSV format. The files contained bare earth lidar elevation measurements in X,Y,Z format. The data were received in Massachusetts State Plane Mainland Zone 2001, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid99 model. The vertical units of the data were feet. CSC performed the following processing for data storage and Digital Coast provisioning purposes: 1. The topographic las files were converted from ASCII to LAS format. 2. The classification of all bare earth points was changed from Class 0 to Class 2. 3. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid99. 4. The topographic las files were converted from a Projected Coordinate System (MA SP Mainland) to a Geographic Coordinate System (NAD83). 5. The topographic las files' vertical units were converted from feet to meters. 6. The topographic las files' horizontal units were converted from feet to decimal degrees. 7. The data were converted to LAZ format.
        1 2013-11-26T00:00:00 The NOAA National Geophysical Data Center (NGDC) received lidar data files via ftp transfer from the NOAA Coastal Services Center. The data are currently being served via NOAA CSC Digital Coast at http://www.csc.noaa.gov/digitalcoast/. The data can be used to re-populate the system. The data are archived in LAS or LAZ format. The LAS format is an industry standard for LiDAR data developed by the American Society of Photogrammetry and Remote Sensing (ASPRS); LAZ is a loseless compressed version of LAS developed by Martin Isenburg (http://www.laszip.org/). The data are exclusively in geographic coordinates (either NAD83 or ITRF94). The data are referenced vertically to the ellipsoid (either GRS80 or ITRF94), allowing for the ability to apply the most up to date geoid model when transforming to orthometric heights.
