What is a Building Footprint? Data, Sources, Uses
A building footprint is the outline a building occupies on the ground. What footprint data contains, the major open datasets, and how to use them at scale.
What is Probable Maximum Loss (PML)? EP Curves, AAL
Probable maximum loss (PML) is the largest loss an insurer expects from one property or a portfolio at a chosen probability. How PML, EP curves, and AAL fit.
What is Stochastic Modeling? Definition, Types, Examples
Stochastic modeling simulates thousands of possible outcomes from random variables. How it works, stochastic vs deterministic, and how cat models use it.
What is Parcel Data? Parcel Numbers, Boundaries, Sources
Parcel data records every piece of land: its boundary, parcel number, owner, land use, and assessed value. Where it comes from and how to use it.
What is a Flood Risk Map? Zones and Depth Grids
A flood risk map shows where flooding is likely, how deep the water would be, and how often it is expected. The flood risk data behind it comes as regulatory flood zones, such as FEMA’s Special Flood Hazard Area, and as modeled depth grids for return periods like the 100-year and 500-year flood. What flood […]
What is Catastrophe Modeling? Cat Models, AAL
Catastrophe modeling, or cat modeling, is the practice of estimating the financial losses a portfolio of insured properties would suffer from low-probability, high-severity events such as hurricanes, floods, earthquakes, and wildfires. A cat model is a stochastic model: it simulates thousands of possible events, applies each to the exposure at every location, and produces a […]
