Overview

SWFWMD regularly uses digital topographic information to support regulatory, land management and acquisition, planning, engineering and habitat restoration projects. LiDAR data will support hydrologic modeling activities associated with the Federal Emergency Management Agency (FEMA), and in the creation of Digital Flood Insurance Rate Maps(DFIRM). The LiDAR data will support the creation of Federal Emergency Management Agency Flood Insurance Rate Maps (FEMA FIRM) and an integrated ground and surface water model for Hillsborough County. The data were classified into 7 classifications; (1) unclassified, (2) ground, (6) buildings, (9) water, (11) wetlands (reclassed by OCM to 16), (12) overlap points, (23) reserved for ASPRS definition (reclassed by OCM to 15), (30) reserved for ASPRS definition, and (31) reserved for ASPRS definition (reclassed by OCM to 10). Cooner & Associates performed the vertical accuracy and horizontal accuracy QA/QC analysis. This data set is an LAZ (compressed LAS) format file containing LIDAR point cloud data.
