Understanding Lidar and Flood Mapping

What is the primary purpose of using lidar data in flood mapping?

• To provide a detailed representation of the terrain

• To measure the speed of floodwaters

• To create a visual map of the state

• To track the movement of wildlife

What does lidar stand for?

• Laser Data and Recording

• Laser Imaging and Detection

• Light Distance and Reflection

• Light Detection and Ranging

How does lidar technology measure the earth's surface?

• By using a laser to measure the time it takes for a pulse to return

• By analyzing weather patterns

• By recording sound waves

• By capturing images from satellites

Why is it important to have updated floodplain maps?

• To improve the aesthetics of maps

• To track population growth

• To better plan for flood mitigation and understand flood risks

• To ensure accurate weather forecasts

How does the resolution of lidar data compare to older floodplain maps?

• Both have the same resolution

• Lidar data has a higher resolution

• Lidar data has a lower resolution

• Older maps have a higher resolution
