GFDRR / rdl-standard

The Risk Data Library Standard (RDLS) is an open data standard to make it easier to work with disaster and climate risk data. It provides a common description of the data used and produced in risk assessments, including hazard, exposure, vulnerability, and modelled loss, or impact, data.

[Proposal] impact_metric.csv codelist for Vulnerability impact metric #125

Closed odscjen closed 1 year ago

odscjen commented 1 year ago

branching off from https://github.com/GFDRR/rdl-standard/issues/75, the impact_metric.csv codelist needs populated with descriptions and if necessary any extra codes.

Current codes are

Code | Title damage ratio | Damage ratio mean damage ratio | Mean damage ratio probability of exceeding damage limit state | Probability of exceeding damage limit state loss ratio | Loss ratio total loss | total loss number of casualties(fatalities) | Number of casualties (fatalities) casualty(fatality) ratio | Casualty (fatality) ratio annual average loss | Annual average loss downtime | Downtime damage index | Damage index

These impact metric codes relate to those used on the y-axis in vulnerability functions and fragility functions: Code,Title,Description damage_ratio,Damage ratio,The estimated repair cost of an asset divided by the total replacement cost of the asset [0-n] used in vulnerability functions. mean_damage_ratio,Mean damage ratio,The mean value in a distribution of estimated repair costs divided by the total replacement cost of an asset [0-n] used in vulnerability functions. probability,Probability,The probability of reaching or exceeding a damage limit state specified in a fragility function [%]. damage_index,Damage index,"A specified index or classification of damage levels, which may be numeric or non-numeric." loss_ratio,Loss ratio,"The loss to an asset divided by the total replacement cost of the asset [0-n] as a function of damage state, used in damage-to-loss-models." mean_loss_ratio,Mean Loss Ratio,"The mean loss ratio in a distribution of losses divided by the total replacement cost of the asset [0-n] as a function of damage state, used in damage-to-loss-models." downtime,Downtime,"Duration of downtime, used in vulnerability modelling of business or service interruption." casualty_ratio,Casualty ratio,"The number of expected casualties or fatalities as a proportion of total inhabitants of and asset or population [0-1] used in casualty or mortality functions."

Engineering demand functions have a set of structural response value used on y-axis, contained in edp_name.csv

These codes are used in the loss component to describe loss metrics: economic_loss,Total Loss,The monetary value of estimated economic impact or total loss (ground up loss in insurance terminology). Impact_type denotes whether this refers to total, direct, or indirect loss. insured_loss,Total Loss,The monetary value of estimated insured losses. loss_ratio,Loss Ratio,Estimated loss as a proportion of total replacement cost or insured value. Impact_type denotes whether this refers to total, direct, or indirect loss. numCasualties,Number of casualties (fatalities),The estimated number of casualties or fatalities. casualty_ratio,Casualty ratio,Proportion of estimated casualties or fatalities in the total population. aal,Annual average loss,Expected loss over a one-year time period according to long-term averages. Impact_type denotes whether this refers to total, direct, or indirect loss. pml,Probable Maximum Loss,Estimated maximum loss occurring at a given exceedance probability or return period. var,Value at Risk,Estimated minimum loss likely to be equalled or exceeded in a given year for a given probability. tvar,Tail Value at Risk,Estimated losses at or exceeding a specified value at risk VaR (estimate of average losses given that a severity threshold has been exceeded). downtime,Downtime,"Duration of downtime (business or service interruption)."
