چکیده
New remote sensing methods based on narrow-band hyperspectral instruments enable the estimation of vegetation biophysical parameters and leaf biochemicals used to detect nutritional and water stress condition. This paper summarizes new advances in hyperspectral and thermal remote sensing for vegetation monitoring through biochemical and biophysical parameter estimation, discussing the potential for detecting water stress using high-resolution thermal instruments onboard airborne platforms. RESUMEN. Nuevos métodos de teledetección basados en sensores hiperespectrales de banda estrecha permiten potencialmente la estimación de parámetros biofísicos de la vegetación y la detección de la concentración de constituyentes bioquímicos foliares asociados a niveles de estrés nutricional e hídrico. Este artículo resume avances en la detección de estrés nutricional mediante la estimación de parámetros bioquímicos, así como la viabilidad de la detección de estrés hídrico mediante sensores térmicos de alta resolución espacial instalados en vehículos aerotransportados.

Land cover is defined as the physical material of the surface of the earth, including different vegetation covers, bare soil, water surface, various urban areas, etc. Land cover and its changes are very important and influential on the Earth and life of living organisms, especially human beings. Land cover change monitoring is important for protecting the ecosystem, forests, farmland, open spac...

Urbanization-associated land use and land cover (LULC) changes lead to modifications of surface microclimatic and hydrological conditions, including the formation of urban heat islands and changes in surface runoff pattern. The goal of the paper is to investigate the changes of biophysical variables due to urbanization induced LULC changes in Indianapolis, USA, from 2001 to 2006. The biophysica...

Cities are experiencing rapid population growth and consequently extensive urbanization. Land-use/land-cover change is one of the important elements worldwide, which significantly affect the environment. This study aims to describe the emergence of urban heat and cool islands as a result of changes in land-use/land-cover. Land surface temperature over a 32-year period in Isfahan city, Iran was ...
