The purpose of this study is to statistically evaluate the impact urban forestry on heat Island in Umuahia city, located Eastern Nigeria using Land Surface Temperature (LST) time series. LST datasets were extracted from Moderate Resolution Imaging Spectroradiometer (MODIS, MYD11A2 V6) satellite Python and JavaScript Google Earth Engine (GEE) platform. Two microclimate environments considered na...

The United States Climate Change Initiative includes improvements to the U.S. Department of Energy's Voluntary Greenhouse Gas Reporting Program. The program includes specific accounting rules and guidelines for reporting and registering forestry activities that reduce atmospheric CO2 by increasing carbon sequestration or reducing emissions. In the forestry sector, there is potential for the eco...

This paper demonstrates the use of High Dynamic Range (HDR) fisheye images of the sky dome in lighting simulations. The objective is to improve the accuracy of simulations with site specific sky conditions. The luminance information stored at a pixel level in an HDR photograph is used to light the simulated environment through an Image Based Rendering (IBR) technique. The results show that imag...
