|2011 Federal Emergency Management Agency (FEMA) Topographic Lidar: Massachusetts and Rhode Island|
|This data set is a combination of 3 seperate FEMA collections (Blackstone, Charles-Quincy and Narragansett) with similar specifications. See the Ground Control process step for further information on functional areas. Ground Control is collected throughout the AOI for use in the processing of LiDAR data to ensure data accurately represents the ground surface. QA/QC checkpoints, (FVA and CVA - see Ground Control process step for further information) also collected throughout the AOI, are used for independent quality checks of the processed LiDAR data. LiDAR acquisition products include Pre- and Post- flight reports which contain information on the flightlines, equipment parameters, and other pertinant acquisition details. The LiDAR product itself consists of tiles of LAS points which are partially classified such that the bare earth points can be calibrated to the ground surface and tested via the independent QC to ensure the ground surface is accurately represented.|
