An Open, Extensible Data Schema for Multiple Hazards, Exposure and Vulnerability Data
Abstract
To manage disaster risk, the Global Facility for Disaster Reduction and Recovery (GFDRR) Innovation Lab is an active promoter of open data and models. Here we present an open data schema for risk-related data. GFDRR supports a number of national and local risk assessments to assess natural hazard risk and guide disaster risk management actions. The risk assessments are based on catastrophe risk models (cat models) which require a wide range of data. In addition to reference data such as digital terrain models and administrative boundaries, a cat model typically requires data on hazard, exposure and vulnerability. Hazard data provide the spatial distribution of the maximum intensity of an event. For example, the spatial distribution of flood depth, earthquake ground motion, or tropical cyclone wind speed. Exposure data provide the location and attributes of exposed assets. For example, the location of government buildings, their construction attributes and their replacement value; or, the population and information on gender and age distribution. Vulnerability data provide fragility or vulnerability functions that describe the response of the exposure to the forces exerted by a hazard. The attributes that are the major determinants of an exposure's vulnerability is a function of hazard. For example, a home's roof is an important factor for wind vulnerability but plays a minimal role for flooding vulnerability. Currently, most of this information is collected and stored following a variety of in-house formats that are poorly defined. This makes it difficult to merge different data sets for risk assessments and to reuse the data with other tools. GFDRR and the UK Department for International Development have supported three consortia to develop an open, extensible data schema that can be used for multiple hazards, a variety of structural and socio-economic exposure data, and fragility and vulnerability functions and vulnerability indices. This presentation will provide an outline of the data schema, provide information on where to access the schema documentation, and describe a data explorer that will allow a user to find and access data that follows the schema. In addition, we discuss future plans to develop utilities that will allow the risk community to contribute data in a format that follows the schema.
