Federal Emergency Management Agency (FEMA) Region X will be collecting LiDAR data to map 875 square miles of Idaho floodplain from June 8-17, 2011.

June 8 – June 17, Aerometric, a contractor hired by the Federal Emergency Management Agency (FEMA) Region X, will be flying an aircraft-mounted Light Detection and Ranging (LiDAR) laser sensor to map 875 square miles of Idaho floodplain. This LiDAR data will be processed to make enhanced digital topographic maps. IDWR prefers to use LiDAR data for mapping Idaho floodplains because LiDAR is a floodplain mapping best practice for superb accuracy, resolution, precision, cost effectiveness and utility. The aircraft, LiDAR sensor and acquisition crew will be available for interviews, filming and pictures and to answer questions about this technology and its applications from June 8th – June 17th in various Idaho General Aviation Airports near the collection areas below. Call Ryan at IDWR to coordinate a meeting. The aircraft, in the Idaho Falls area June 8th, follows a weather dependant schedule.

LiDAR is a very powerful technology (http://bcal.geology.isu.edu/ for more info) used to understand many different public safety issues, such as: flooding, forest fire fuels modeling, landslides and has numerous other applications such as topographic contours, skyline analysis, digital elevation models, ground cover, et cetera. The LiDAR sensor is a laser and receiver that work together, shooting pulses of light at the surface of the earth from the moving aircraft and the recording information from the laser reflection. LiDAR is capable of producing maps so accurate that error is often measured in millimeters. Floodplain mapping uses approximately 4.223mm resolution and 8 pulse returns per meter, LiDAR quotes at this resolution typically average nearly $1,200.00 per square mile. The LiDAR is being acquired as part of the Idaho Risk Mapping, Assessment and Planning (Risk MAP) Program. The vision for Risk MAP is to deliver quality data that increases public awareness and leads to action that reduces risk to life and property (http://www.fema.gov/plan/prevent/fhm/rm_main.shtm). Local Idaho communities are the primary beneficiary of this 100% FEMA funded effort. The light emitted from the instrument will not hurt eyes.
