Count Component Title Abstract
1 2004 Federal Emergency Management Agency (FEMA) Bare Earth Topographic LiDAR: Connecticut River LiDAR data is remotely sensed high-resolution elevation data collected by an airborne collection platform. The LiDAR files were converted from .PTS format to LAS V1.2. All data is Bare Earth, with 99% of all buildings removed and 95% of all vegetation removed. There is no information available for return number, scan angle, GPS time, or intensity. This data set covers approximately 1,233.83 square miles (3,195.6 sq km) of the Connecticut River.

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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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

    Count Component DateTime Description
    1 2013-03-01T00:00:00 The NOAA Coastal Services Center (CSC) received the topographic files in .PTS format. The files contained lidar elevation measurements. The data were received in Connecticut State Plane coordinates, NAD83 (Zone 0600) 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 .PTS files were converted to LAS V1.2 2. All points were set to Class 2 (Bare Earth) 3. The topographic las files were converted from a Projected Coordinate System (Connecticut State Plane) to a Geographic Coordinate system (NAD83). 4. The topographic las files' horizontal units were converted from US survey feet to decimal degrees. 5. The topographic las files were converted from orthometric (NAVD88) heights to ellipsoidal heights using Geoid99. 6. The topographic las files' vertical units were converted from survey feet to meters. 7. The data were converted to LAZ format.
    1 2013-05-15T00:00:00 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.
