Abstract

A method for designating vegetation as potential impact vegetation includes identifying data relating to target vegetation from a dataset and determining a reach distance of the target vegetation. The reach distance includes a distance from a point on a ground to a point of the target vegetation that is farthest from the point on the ground. The method also includes comparing the reach distance of the target vegetation with a closest distance between the point on the ground and a structure to produce a compared reach distance value and determining a health indicator value for the target vegetation. The method further includes comparing the health indicator value of the target vegetation to a health indicator threshold value and designating the target vegetation as having a potential to impact the structure based on the compared reach distance value and the comparison of the health indicator to the health indicator threshold.

and

designating the target vegetation includes designating the target vegetation as having a potential to impact the structure if the reach distance is greater than or equal to the base distance.

5. The method of claim 1, wherein the closest distance between the point on the ground and the structure is a base distance;

designating the target vegetation includes designating the target vegetation as having a potential to impact the structure if the reach distance is greater than or equal to the base distance less a threshold distance; and

the threshold distance is equal to a predetermined distance extending from the structure.

6. The method of claim 5, wherein the predetermined distance extending from the structure includes a value associated with a safety buffer zone, and the safety buffer zone includes at least one of a power line safety buffer zone, a railroad track safety buffer zone, a railroad overhead conductor safety buffer zone, a phone line safety buffer zone, a phone line safety buffer zone, a road safety buffer zone, a highway safety buffer zone, and a communication cable safety buffer zone.

7. The method of claim 1, wherein identifying data relating to target vegetation from a dataset includes identifying segments of the target vegetation.

8. The method of claim 6, wherein the identifying the segments includes filtering segmentation input data with a filter that alters a number of inputs to a filter operator or weights of individual entries among the inputs, based on one or more vegetation properties corresponding to a filter location.

9. The method of claim 6, wherein the identifying the segments includes, for each identified segment, altering one or more segmentation parameters of the segment based on one or more properties of a seed point from which the segment is started.

10. The method of claim 1, wherein,

determining a health indicator value for the target vegetation includes determining, by the processor, the health indicator value for the target vegetation;

and

comparing the health indicator value of the target vegetation includes comparing, by the processor, the health indicator value of the target vegetation with the health indicator threshold value.
