2-2-1- Step1: Data collection
The organization of parks and green space of Isfahan city provided a
database of 770561 surveyed trees, in which their biophysical attributes
like the height, DBH, health status, and their pest and disease were
recorded. In order to estimate the biomass of a single tree, we used
biophysical variables of DBH and height of a tree recorded in the
survey. Further, we used a topographic map of 1/2000 provided in 2017.
Furthermore, it was used Worldview2 satellite image of the region to
model carbon sequestration of the trees (the trees that were not
surveyed) throughout the study area.
