* » Abstract |
The data contained in these files contain hydrographic and topographic data collected by the CHARTS (Compact Hydrographic Airborne Rapid Total Survey) system along the Lake Erie coast of Pennsylvania and in Lake Michigan for the Manitou Islands, Grand Traverse Bay, and Little Traverse Bay. The Grand Traverse Bay and Little Traverse Bay data were processed at a later date than the Pennsylvania coast and Manitou Islands data. The U.S. Army Corps of Engineers collects and maintains LiDAR data including orthophotos in coastal areas of the United States and its territories. The Corps acquires this data in the course of performing its mission of flood control, navigation, environmental engineering, and support for the Army and others. This is a bare earth data set. It was bare-earthed by the NOAA Office for Coastal Management. Lake Erie (PA shoreline) dates of collection: 17-20 Aug 2007 Lake Michigan (Manitou Islands) dates of collection: 11-20 Sept 2007 Lake Michigan (Grand Traverse Bay and Little Traverse Bay) dates of collection: 10-18 Sept 2007 Original contact information: Contact Org: JALBTCX Title: Data Production Manager Phone: 228-252-1111 Email: shoals-info@sam.usace.army.mil |
* Purpose |
These data were collected as a part of the National Coastal Mapping Program (NCMP) to depict the elevations above and below the water in the Pennsylvania and Michigan coastal zone. |

» 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 20 kHz and hydrographic data at 3 kHz. The system also collects RGB imagery at 1 Hz. 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 data are broken into files, with each covering approximately 5 km along the shoreline. 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. The bathymetry files contain all of the returns from the bathymetric sensor which include returns both above and below the water. |

» Description |
The NOAA Office for Coastal Management (OCM) received topo and hydro files in ASCII format. The files contained Lidar elevation and intensity measurements. Both the topo and hydro points were classed as 'never classified.' The data were provided in Geographic coordinates and ellipsoidal heights and in IGLD85 heights. OCM performed the following processing to the ellipsoidal height data for data storage and Digital Coast provisioning purposes: 1. LASEdit was used to convert the ascii formatted files to las format. 2. Both the topo and the hydro points were classified as never classified. Hydro points were changed to class 11 (bathymetry) and topo points were classified to class 2 (ground or bare earth). 3. The LAS data were sorted by latitude and the headers were updated. The Grand Traverse Bay and Little Traverse Bay data were received by the NOAA OCM at a later date from the previoulsy processed data (Lake Erie - PA Shoreline and Lake Michigan - Manitou Islands) in this data set. These later received data were processed from the TL (last return topography) and H (bathymetry) ASCII files. The data were converted to las format using lastools. The H files were converted from IGLD85 vertical datum to NAVD88 using Vdatum and then converted to ellipsoid heights using GEOID03. Points were re-classified from 0 (never classified) to 11 (NOAA OCM bathymetry). These data were processed by NOAA OCM on 201206. |
