The attached image shows a kernel density estimate based on tree locations. A population field was used which included tree height and the search distance was set to approximately 5.64 m. I am having a hard time trying to justify/explain the units on the output, especially since the ground-based average tree height is 0.59 meters. The documentation states that if a population field is specified, the population value will be used to weight the KDE. For example, if I assign the population field to "Tree Height (m)" a tree that is 3m tall will be counted 3 times for the KDE.
- Is it appropriate to weight the KDE based on tree height?
- What do the actual values mean in the attached graphic? Are these points estimates of average tree height in a given area?
