This metadata record describes the 1798 las files (version 1.3) received by the NOAA Office for Coastal Management (OCM), provided by the Miami-Dade County Information Technology Department (ITD). Aerial Cartographics of America, Inc. (ACA) LB 6748, operating under the authority of Miami-Dade County Aviation Department, as per contract number E10-MDAD-03, was tasked by Miami-Dade County's Information Technology Department (ITD) to provide LiDAR data for 1612 square miles. The dates of collection were February 15, 17, 18, 19, 20, 21, 2015 and April 2, 3, 11, 12, 13, 2015, collected in 366 flight lines. Tiles were delivered to follow FDOR tiling scheme. Upon receipt and review of the data from Miami-Dade County's ITD, NOAA OCM noticed some inconsistencies in the classifications of the data and informed Miami-Dade County ITD. OCM decided to improve the usability of the data by contracting out the reclassification of the lidar las files. The original, unclassified point data were sent to Tetra Tech by Aerial Cartographics of America (ACA) for the re-classification work. The re-classified point data were delivered to NOAA OCM. The data classifications included are: 1 (unclassified), 2 (ground), 6 (building), 7 (low noise), 9 (water), 10 (buffered ground around breaklines), 17 (bridge decks), 18 (high noise). NOAA OCM did not determine a new vertical accuracy for the re-classified data. The vertical accuracy value listed in this metadata record is the value for the original Miami-Dade County's ITD data. In addition to these lidar point data, the bare earth Digital Elevation Models (DEMs) created from the lidar point data are also available. These data are are available for custom download at the link provided in the URL section of this metadata record. Hydro breaklines and a large building footprint (with highest elevation) are also available. These data are available for download at the link provided in the URL section of this metadata record. Please note that these products have not been reviewed by the NOAA Office for Coastal Management (OCM) and any conclusions drawn from the analysis of this information are not the responsibility of NOAA or OCM. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
