snail: spatial networks impact assessment library

Climate hazards pose increasing risks to people and society. Impact assessment uses probabilistic estimates of various hazards (fire, flood, landslide) to calculates the exposure, vulnerability and risk. In particular, parts of infrastructure networks (roads, power grid, water supply) may be directly exposed to climate hazards, with knock-on indirect effects on people, society, firms and the economy, which may be much wider than the direct impact on a single stretch of road or electricity substation.

snail provides a reusable library for analysis, setting clear data requirements and implementing the details of probabilistic spatial network failure analysis given a spatial network, usage, vulnerabilities and hazards. It aims to support developer-users who will use and extend this to implement specific analyses, and may build it into more end-user-friendly toolkits or platforms.
