Wind Speed Probability

These tile layers represent Wind Probability by relative year.

Values represented in these tiles are based on 3-second wind gust speed which are what can most often cause damage to buildings and are generally 1.28 times faster than a 1-min sustained wind speed.

Parameters

The relativeYear represents a year value relative to the current year. For example, 0 would represent this year and 5 would represent this year plus 5 years from now. In order to reduce developer maintaince, we suggest using the relative year notation to implement updates.
