Resilience of road segments - Dominica, 2015-2025
收藏资源简介：
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 Accessibility https://zenodo.org/uploads/15366616 Only freely accessible data is used. Disclaimer – This dataset is provided solely for research purposes. It is based on available data and has not been verified or approved by any local authority. The dataset represents the outcome of the applied methodology and research judgments, and does not reflect the official policies or positions of the authorities of Dominica. Stakeholder Relevance Used for determining which roads are most endangered for floods and landslides, as a basis for early warning and risk-informed planning Limitations/Assumptions Flood maps were made with a 5-meter pixel size.
