NASA | Landsat Tracks Urban Change and Flood Risk

The video discusses the severe impact of floods, including financial damages and loss of life. It explains the role of flood insurance rate maps in assessing flood risk and the need to update these maps due to changing environmental factors. Satellite imagery, particularly from Landsat satellites, is highlighted as a tool for tracking urban changes that affect flood risk. The video emphasizes the importance of understanding urbanization's impact on flood characteristics and how this data helps manage flood-related costs.

What is the primary purpose of flood insurance rate maps?

• To predict weather patterns

• To depict flood zones and assess specific risks

• To calculate insurance premiums

• To map out urban development

How do Landsat satellites contribute to flood risk management?

• By predicting rainfall

• By tracking urban changes over time

• By providing real-time flood alerts

• By mapping river courses

What is the role of the product called Newsie in flood risk assessment?

• It mines satellite images to identify urbanization trends

• It predicts future flood events

• It calculates flood insurance rates

• It monitors weather conditions

What is a significant consequence of increased impervious areas due to urbanization?

• Altered flood characteristics and increased flood risk

• Improved water quality

• Enhanced groundwater recharge

• Decreased flood risk

Why is it important to track urban change from space?

• To improve satellite technology

• To help people understand and manage their flood risk

• To reduce construction costs

• To enhance city aesthetics
