Social Vulnerability and Integrate Risk calculators

Registered by Lars Butler on 2013-07-25

Terminology

Zone:
  A [normally (relatively) small] arbitrary geographical region (represented as a polygon) which defines a study region. It is typical for these regions to be defined on the provincial/county/cantonal level, but the regions are purely arbitrary. For example, in the United States, zones may be defined in terms of the counties within a state. In Switzerland, zones may be defined as the 26 cantons. However, these zones can be even larger or smaller (ranging from entire countries/regions to individual wards/districts within a city).

Socio-Economic Variables:
  Attributes associated with a Zone which characterize an area. Attributes can include information about population, infrastructure, healthcare resources, environment, and education, just to name a few. In all, there roughly a few dozens of different parameters which fall into these categories.
  These variables are taken into account when a Social Vulnerability Map is computed.

Loss Map:
  A risk calculation output from the oq-engine. Comprised of a collection of geographical points with one or more loss values for a given asset.

Preparing Input Models

Input models are expected to be a GeoJSON FeatureCollection, defining zone polygons with their associated SE Variables. We may support shapefiles as well in the future (since GIS tools such as QGIS can convert easily between GeoJSON<->shp, and since shapefiles are the typical format for many common geospatial modeling tasks), but for the first iteration we plan to only support GeoJSON.
