Calculating Tree Risk with GeoVision from Precisely

Every year the combination of trees and weather cause significant structural damage to buildings in Australia. The major factors contributing to the risk posed by each tree is its health, species, proximity to the building, direction from the tree to the building and the height of the tree. Precisely GeoVision provides reliable information regarding the height of trees and their proximity and direction to buildings. This information has been analysed and summarised to create the GeoVision Tree Risk data product.

Who would use GeoVision Tree Risk data? The following agile stories give examples of possible uses for the Tree Risk data.

As an insurance actuary
I need to assess the aggregate risk to my portfolio of tree damage during either specific or generalised wind events over a select geographic region in order to report the overall risk to re-insurers and shareholders.

As an insurance actuary
I need to assess the risk of tree fall during weather events to individual buildings where Tree Risk is a function of three factors: the height of the tree; the distance from the building; and the direction from the tree to the building so that I can calculate premiums and maintain the profit margins of the portfolio.

As an insurance agent or government representative
I need to assess the risk of tree fall during weather events to individual buildings where tree risk is a function of three factors: the height of the tree; the distance from the building; and the direction from the tree to the building so that I can provide this information to property owners as a preventative measure.

As an arborist
I want to identify properties where the risk of tree fall damage is high to focus my marketing and sales efforts to improve profits.

As an emergency services manager
I need to gauge the response required for a forecast storm event. I need to assess the potential number of affected properties and the likely cumulative impact.
