Count Component Title Abstract
1 2011 MDEQ Tennessee-Tombigbee Waterway Lidar Survey Collect and deliver high-density elevation point data derived from multiple-return light detection and ranging (LiDAR) measurements for use in supporting topographic analysis, including applications such as flood plain mapping. The Nominal Point Spacing Value for the final lidar is 3.2 ft (~1 m). Deliver LiDAR Bare Earth and Contour lines within the areas designated in areas of Clay, Itawamba, Monroe, and Lowndes Counties to aid in visual interpretation of Flood Basin elevations and for addition to the MDEM elevation dataset. Comply with mapping guidelines and specifications as stated in the FEMA Procedure Memorandum No. 61

        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be aware that temporal changes may have occurred since this data set was collected and some parts of this data may no longer represent actual surface conditions.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 2011-06-01T00:00:00 The ABGPS, IMU, and raw Optech LiDAR data are integrated into the Optech post processor software. The resultant file is in a LAS binary file format. The LAS file version 1.2 formats can be easily transferred from one file format to another. It is a binary file format that maintains information specific to the LiDAR data (return#, intensity value, xyz, etc.). The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and NAVD88 2004.65 vertical datum.
        1 2011-06-01T00:00:00 The unedited data are classified to facilitate the application of the appropriate feature extraction filters. A combination of proprietary filters is applied as appropriate for the production of bare earth digital terrain models (dtms). Interactive editing methods are applied to those areas where it is inappropriate or impossible to use the feature extraction filters, based upon the design criteria and/or limitations of the relevant filters. These same feature extraction filters are used to produce elevation height surfaces. The LiDAR mass points were delivered in American Society for Photogrammetry and Remote Sensing LAS 1.2 format. The header file for each dataset is complete as define by the LAS 1.2 specification. The data was classified as follows: Class 1 = Unclassified. This class includes all non-ground classified points. Class 2 = Ground. Class 7 = Low Points. Class 9 = water. Class 9 = water. Class 10 = Ignored. Class 11 = Overlap Points.
        1 2011-06-01T00:00:00 Conversion from Geodetic coordinates NAD83 into Mississippi state plane zone 16 East using NAD83 and conversion from ellipsoid heights (us feet) into orthometric heights using NAVD88 (US Survey Foot). Files are orthogonally tiled based to a 1500m x1500m extent, and labeled with a "Tile_ID" attribute.
        1 2013-09-16T00:00:00 The NOAA Coastal Services Center (CSC) received topographic files in .laz format from the Mississippi Department of Environmental Quality (MDEQ). The files contained lidar elevation measurements. The data were received in Mississippi State Plane East 2301, NAD83 coordinates and were vertically referenced to NAVD88 using the Geoid09 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 laz files were converted from a Projected Coordinate System (Mississippi State Plane East 2301) to a Geographic Coordinate system (NAD 83). 2. The topographic laz files' horizontal units were converted from feet to decimal degrees. 3. The topographic laz files were cleaned of error points above 535 ft and below 100 ft. 4. The topographic laz files' were converted from NAVD88 elevations to NAD83 ellipsoidal elevations using Geoid03 5. Classification 11 was moved to classification 12 due to CSC system requirements (class 11 is reserved for bathy points, though these points are overlap points, Class 12).
        1 2013-10-17T00:00:00 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.
