CTP Webinar: Using LiDAR for LOMAs
Locations: CTP Information Exchange Webinar
Time: Wednesday, Mar 6, 2019, 1:00 PM - Wednesday, Mar 6, 2019, 2:30 PM

FEMA has recently developed guidelines regarding the use of LiDAR (Light Detection and Ranging) derived topographic data for Letter of Map Amendment (LOMA) applications. This webinar will provide information on the Minnesota pilot project where this concept was tested, a Montana project that compared Lowest Adjacent Grades (LAGs) derived from LiDAR with field surveys and FEMA’s new guidelines.
