For the 3-30-300 guidelines, the rule indicated by the "3" is the ability to see 3 trees out of residential windows. This can be computed in the Tygron Platform by calculating the locations of residential walls, and the sightlines onto trees.
Notes
- The resulting Combo Overlay has values of 0 where there are walls without sight of a tree, and values of 1 where there are walls with sight of a tree.
- Although the different steps in the calculation may produce coarse results, over a large scale the imperfections can balance out and the calculation as a whole can provide relevant insights into the compliance to the guideline.
- At this time this calculation can only determine sightlines to a tree, not neccesarily to the prescribed 3 or more trees. However, in most urban environments trees exist in groups which can alleviate the discrepancy somewhat.
