Abstract

One of the most important information in urban forestry is acquaintance of urban landscape’s area. Nowadays, in several countries various methods are used to achieve this aim. Since there is not any complete method to study the urban forest’s status in Iran, it is impossible to manage these resources properly. Hence, in this research, systematic random SAMPLING methods and Ikonos satellite imagery in Google Earth software were used to assess the area of CANOPY COVER of road trees for evaluating the accuracy of satellite images in their CANOPY COVER estimation. The systematic random SAMPLING was also considred as the base for comparisons. The crown of trees in street margins was calculated, and then the canopy of these trees in satellite images scale 1/2000 was also calculated. After georeferencing and geometric correction of the images in ENVI software, CANOPY COVER and area of each tree on the street were measured. The results of paired t-test (df = 118, t =1.69) showed that the outcomes of two calculation methods do not have any significant difference (in 95% confidence level). The result of regression analysis showed that satellite images could be used in estimating road trees CANOPY COVER (R2=0.95). Therfore, regarding to the results of this research, assessment of urban forest CANOPY COVER using satellite imagery could be proposed to calculate the total CANOPY COVER of road trees and increase the awareness of changes in these valuable resources in short periods of time.
