Post-Hurricane
Water Inundation Analysis

Mapping flood inundation due to a hurricane.

Demo Highlights

Large areas are inundated, and new rivers/creeks are formed on the hills

Description

This application maps water inundations before and after the hurricane in Caribbean Islands in Sep 2017. The Normalized Difference Water Index (NDWI) is used to eliminate inundated areas. Satellite imagery at each location prior and after the hurricane are retrieved from Planet.

Post-Hurricane
Vegetation Analysis

Mapping vegetation cover damage due to a hurricane.

Demo Highlights

Major reduction in vegetation cover; particularly, near rivers and flood inundated regions.

Description

lThe goal of this application is to evaluate the extent of vegetation cover loss after the two major hurricanes in the Caribbean Islands in Sep 2017. The Normalized Difference Vegetation Index (NDVI) is used to assess vegetation greenness, and subsequently coverage. Satellite imagery at each location prior and after the hurricane are retrieved from Planet.

British Columbia
Wildfires Analysis.

Analyzing the extent of burn area after wildfires

Demo Highlights

Severe canopy loss after the wildfire and major risk for nearby infrastructure

Description

The goal of this application is to assess the burn area after wildfires in British Columbia in Jul 2017. The Normalized Difference Vegetation Index (NDVI) is applied to pre- and post- fire imagery, and reductions in NDVI are used as an indicator of burn area. Satellite imagery at each location are retrieved from Planet.
