Infra-red remote sensing

The purpose of the study "Monitoring surface water bodies changes from sentinel-2A imagery with modified normalized difference water index: Application in Dalat, Lam Dong, Viet Nam" is to identify surface water body changes using Sentinel-2 MSI (Multi-Spectral Instrument) data, one of the latest types of remote sensing satellite data. The results of the research show that by using Sentinel-2 MSI imagery, MNDWI (Modified Normalized Water Index) is the appropriate parameter to detect surface water areas in the studied area, with an overall accuracy > 0.92 and Kappa coefficient > 0.84.

In this research, remote sensing technology was used to evaluate urban development and its thermal characteristics through mapping impervious surfaces and evaluating thermal infrared images. The study is carried out in the northern part of Ho Chi Minh City, which is experienced an accelerated urban development since the end of 1980s. Landsat and Aster images were used to calculate the variation in urban impervious surfaces from 1989 to 2006. Thermal bands were processed to obtain land surface temperatures for investigating the urban heat island effect...

The genesis of this book began on the sunny shores of southern France in September 1993. For five days in the delightful Mediterranean coastal town of La Londe Les Maures, a gathering occurred of a group of scientists interested in furthering both the understanding and use of thermal infrared (TIR) remote sensing data for analysis of land surface processes.

Signal processing has been playing an increasingly important role in remote sensing, though most remote sensing literatures are concerned with remote sensing images. Many data received by remote sensors such as microwave and geophysical sensors, are signals or waveforms, which can be processed by analog and digital signal processing techniques.
