Abstract
Canopy density estimation based on the empirical method using remote sensing data needs field measurement of canopy density data. There are several methods to obtain canopy density data, and it can be divided into downward and upward measurement. Those two methods have different term used, and it is possible to produce different result. This study aims to compare aerial photography from UAV and hemispherical photography that represent downward and upward method, respectively. The results showed downward method produces the higher canopy density than upward method. The regression analysis showed upward method provides the better method in canopy density estimation, however the term of downward measurement is more appropriate to canopy density term
