Event Filter Locations Tab
You can specify a geographical area in order to create an event set filter for a catastrophe peril analysis. The analysis considers events inside of the area that you have specified. You define this geographical area by entering a series of latitudes and longitudes. You must enter at least three latitude/longitude pairs in order to apply an event set filter.
Consider the following when defining event set filters:
The Touchstone event filters use only the first landfall details for events that make multiple landfalls.
If you define multiple filter criteria, the analysis considers only the events that meet all the criteria you have specified.
If the event filter that you have defined excludes all events, or the filters that you have specified are not supported for the event set that you are running, the analysis proceeds and may potentially return no losses.
-
You can define rules and location filters only for earthquakes, tropical cyclones, and terrorism events.
-
For Wind events, if you define a polygon, Touchstone filters the events by making sure that the first landfall point is within this polygon.
-
You can define filters by model ID and event ID for all perils.
-
Once you have defined a filter, click Apply to save your changes before defining additional filters.
The Locations tab within the Event Filter window contains the following controls that enable you to define geographical filters for an event set filter:
Field |
Description |
---|---|
Latitude |
Specifies the latitude for one latitude/longitude pair for this event set filter. Enter the desired latitude. Then, enter the desired corresponding longitude. You must enter at least three latitude/longitude pairs in order to create a locations event set filter. |
Longitude |
Specifies the longitude for one latitude/longitude pair for this event set filter. Enter the desired longitude. You must also enter the desired corresponding latitude. You must enter at least three latitude/longitude pairs in order to create a locations event set filter. |
