Science Case Name

Multi-hazards in the Caribbean SIDS

Dataset Name/Title

Resilience of road segments - Dominica, 2015-2025

Dataset Description

The dataset described the resilience of the main road segments to floods and landslides.

Key Methodologies

Calculating the resilience of road segments by analysing the impact (and the robustness) and the recovery time using classes, which were combined into a resilience score.

Temporal Domain

Erika: 2015, Maria: 2017, other maps are for the situation in 2025

Spatial Domain

Dominica, UTM WGS 84 Zone 20N

Key Variables/Indicators

Resilience of road segments to floods and landslides. The dataset is made by combining robustness with recovery time indicators. 

Data Format

The data are all in Zip format, and the zip files contain ESRI Shapefiles.

Source Data

Openstreetmap, Google OpenBuildings, Dominica Road Asset Management System
