How Earth Observation plays a crucial role in Flood Mapping

Remote sensing and earth observation play a vital role in reducing the effects of life-threatening floods. It requires consistent, frequent inspections and analysis of trends and patterns to identify threats beforehand.

How Earth Observation plays a crucial role in Flood Mapping

With the environment at threat with the rising sea levels, there is an immediate need for mapping flood levels across nations in a coordinated manner.

Floods are one of the most common natural hazards that cause social and economic loss across the world. They are universal and a part of the natural hydrological cycle. 

Apart from being unpredictable, they may also cause loss of life and valuable property if not monitored and planned for. 

Role of Earth Observation

Remote sensing and earth observation play a vital role in reducing the effects of life-threatening floods. It requires consistent, frequent inspections and analysis of trends and patterns to identify threats beforehand. 

Apart from ground information, which is limited by scope and area, earth observation data is crucial for decision making and contributes substantially to data about flood-prone areas.

Satellite data can help assess the extent of destruction and damage and also help in making contingency plans. It is essential for satellite data to be in sync with the ground acquired data to make sure that aid is provided timely and relief is sent to areas most in need.

Effective flood management requires coordination and integration of data from multiple sources such as geospatial data, data collected on the ground, remote sensing data, and satellite imagery. 

Importance of Data

Satellite data is essential to collect information about heavy rainfall and flood-prone areas so that the impact and potential of the hazards can be assessed and analysed.

Satellite data is a simple and efficient way of analysing flood-prone areas. It is cost effective and quick. The information is updated regularly and can help make evacuation and mitigation plans. 

It helps in monitoring the extent of damage and help reduce costs across regions by pre-planning evacuation and aid.

Surveillance and monitoring of these areas are done throughout the year to assess potential threats. Seasons of heavy rainfall are times of high alerts when there is an improved watch on the flood-prone areas.

The near real-time satellite data helps make close guesstimates and protect local and regional areas from life-threatening situations.

Satellites, earth observation, and remote sensing all play a crucial role in flood mapping and monitoring. Without these tools, it would be next to impossible to protect life and property in advance.
