| * » Abstract |
The LIDAR-derived data was collected in the Blackstone River area. This data supports the Federal Emergency Management Agency's specifications for mapping floodplains. These efforts required detailed elevation data and models, such as those available from LIDAR sensing. The data have also been made available to aid in other projects that require detailed surface, vegetation and/or structure elevations. Buildings classed as ground. |
| * Purpose |
The purpose of this LiDAR data was to produce high accuracy 3D elevation based geospatial products for coastal flood mapping. The following regions of Rhode Island are included in this project |

Horizontal accuracy was not reported, therefore assuming 100 cm accuracy |
| Vertical Positional Accuracy |
RTK collected in coincidence; Quantitative Value: 0.185 meters, Test that produced the value: Reported as Quality level 4, with an point spacing of 1.3 m, therefore inference was that vertical accuracy would need to meet 18.5 cm |

The ABGPS, IMU, and raw LiDAR data are integrated into the post processor software. The resultant file is in an ASCII file. It is a binary file format that maintains information specific to the LiDAR data. The resultant points are produced in the geodetic coordinates referenced to the NAD83 horizontal datum and GRS80 vertical datum. - Projection Transformation The data was processed in the native UTM zone in meters and then transformed to the UTM Zone 18 final projection system and meters using an in-house transformation software. |

The NOAA Office for Coastal Management (OCM) received topographic PNT text files as part of the delivery from FEMA, referenced to UTM Zone 18 in meters horizontally but NAVD88 using the Geoid03 model vertically. OCM performed the following processing for data storage and Digital Coast provisioning purposes: 1. The LAS files were converted from PNT files to text files (txt) 2. The TXT files were converted to LAS files with txt2las (lastools), designating those points as Class 2 - Ground. 2. The LAS files were converted from orthometric (NAVD88) heights to ellipsoidal heights using the Geoid03 model. |
