Comparing canopy density measurement from UAV and hemispherical photography: ...IJECEIAES
UAV and hemispherical photography are common methods used in canopy density measurement. These two methods have opposite viewing angles where hemispherical photography measures canopy density upwardly, while UAV captures images downwardly. This study aims to analyze and compare both methods to be used as the input data for canopy density estimation when linked with a lower spatial resolution of remote sensing data i.e. Landsat image. We correlated the field data of canopy density with vegetation indices (NDVI, MSAVI, and AFRI) from Landsat-8. The canopy density values measured from UAV and hemispherical photography displayed a strong relationship with 0.706 coefficient of correlation. Further results showed that both measurements can be used in canopy density estimation using satellite imagery based on their high correlations with Landsat-based vegetation indices. The highest correlation from downward and upward measurement appeared when linked with NDVI with a correlation of 0.962 and 0.652, respectively. Downward measurement using UAV exhibited a higher relationship compared to hemispherical photography. The strong correlation between UAV data and Landsat data is because both are captured from the vertical direction, and 30 m pixel of Landsat is a downscaled image of the aerial photograph. Moreover, field data collection can be easily conducted by deploying drone to cover inaccessible sample plots.

Slide presentations developed to demonstrate how Information and Communication Technologies (ICTs) be used to address climate change, and why ICTs are a crucial part of the solution – i.e. in promoting efficiency, Green Growth & sustainable development, in dealing with climate change and for climate and environmental action. These slide presentations were delivered in February 2011 in Seongnam, near Seoul in Korea.
These presentations were developed and delivered over 2.5 days on the occasion of a Regional Training of Trainers Workshop for upcoming Academy modules on ICT for Disaster Risk Management and Climate Change Abatement. These modules were developed as part of the Academy of ICT Essentials for Government leaders developed by the United Nations (UN) Asia Pacific Centre for ICT Training (APCICT), based in Songdo City, in the Republic of South Korea.
These presentations were developed in 2011, and are somewhat out of date, but most of the principles still apply. Module 10, which has been published, does not include much of the information outlined in these presentations, which are fairly technical. They were developed to address a significant gap in understanding of the technical basis of using ICTs for climate action and because there is a clear bias in development circles against the importance of dealing with climate change mitigation in developing countries. These presentations are an attempt to redress this lack and are published here with this purpose in mind.
The author, Richard Labelle, is presently working on updating these presentations to further highlight the importance of addressing climate change and the important role that technology including ICTs, play in this effort.
