Abstract:

The data contained in these files contain topographic data collected by the CHARTS system along Lake Michigan, Indiana. The data are broken into boxes. The box layout index is provided by the shape file, "in_boxes.shp", and the box numbers for labels are in the "Box" field of the shape file. The data file names are based on the year, project, area name, box number, and product type. An example of the file name is "2008_NCMP_IN_Michigan_07_02DS08070_006_080916_1955_A_00452.las." The 14th digit within the file name corresponds with the box names used. The data was collected and processed in geographic coordinates and ellipsoid heights. The positions are relative to NAD83 in decimal degrees of longitude and latitude. The heights were converted from ellipsoid to orthometric heights using the Geoid03 model with the results in meters. The date and time of each point are also MM:SS.SSSSSS. The format of the file is LAS version 1.0

Lineage

Process Steps

Process Step 1

CC ID: 1139430
Description:

These data were collected using the CHARTS surveys system. It is owned by the Naval Oceanographic Office and Operated through contract. The system collects topographic lidar data at 20kHz and hydrographic data at 3kHz. The system also collects RGB imagery at 1Hz. A CASI-1500 hyperspectral line scanner is integrated with the system as well. Aircraft position, velocity and acceleration information are collected through a combination of Novatel and POS A/V equipment. Raw data are collected and transferred to the office for downloading and processing in SHOALS GCS software. GPS data are processed using POSPac software and the results are combined with the lidar data to produce 3-D positions for each lidar shot. These data are edited using Fledermaus software where anomalous data are removed from the dataset. The edited data are written to 5 km tiles along the shoreline using chartsLAS, a program written by NAVO. This program reads data from the original binary format files and produces separate ASCII files for first and last return data. The data are converted from ellipsoid to orthometric heights, based on the GEOID03 model, within the chartsLAS program.

Process Date/Time: 2009-01-01 00:00:00

Process Step 2

CC ID: 1139431
Description:

The NOAA Office for Coastal Management (OCM) received the data as unclassified files in ASCII format. The files contained LiDAR intensity and

elevation measurements. OCM performed the following processing on the data for data storage and Digital Coast provisioning:

1. The data were converted from ASCII to las format.

2. The data were classified as 1 for the topo data (no bare earth) using the topo last (TL) elevation and 11 for the hydro data.

3. The data were converted from NAVD88 heights to ellipsoid heights using Geoid03.

4. The LAS header fields were sorted by latitude and updated.

Process Date/Time: 2011-05-01 00:00:00

Process Step 3

CC ID: 1139432
Description:

Times had originally been stored as POSIX seconds when converted to LAS. This was switched to adjusted GPS time (GPS seconds - 1e9) to conform to the LAS 1.2 standard.
