A Review of Landsat TM/ETM based Vegetation Indices as Applied to Wetland Ecosystems


DOI: https://doi.org/10.30564/jgr.v2i1.499

Abstract


A review of vegetation indices as applied to Landsat-TM and ETM+ multispectral data is presented. The review focuses on indices that have been developed to produce biophysical information about vegetation biomass/greenness, moisture and pigments.In addition, a set of biomass/greenness and moisture content indices are tested in a Mediterranean semiarid wetland environment to determine their appropriateness and potential for carrying redundant information.The results indicate that most vegetation indices used for biomass/greenness mapping produce similar information and are statistically well correlated. 


Keywords


Greenness determination; Mediterranean wetland areas; Moisture estimation; Remote sensing; Vegetation spectral indices; Thematic Mapper sensor

Experimental Simulation of Red Sprites in a Laboratory

Experimental Simulation of Red Sprites in a Laboratory DOI:  https://doi.org/10.30564/jasr.v5i3.4858 Abstract Over the past three decades, research of high-altitude atmospheric discharges has received a lot of attention. This paper presents the results of experimental modeling of red sprites during a discharge in low-pressure air. To initiate ionization waves in a quartz tube, an electrodeless pulseperiodic discharge fed by microsecond voltage pulses with an amplitude of a few kilovolts and a repetition rate of tens of kHz were formed. In this case ionization waves (streamers) have a length of tens of centimeters. The main plasma parameters were measured at various distances along the tube. The measurements confirm the fact that ionization waves propagate in opposite directions from the zone of the main electrodeless discharge, just as it happens during the formation of red sprites.

Analysis of Chinese Citizens’ Perception and Its Differences of City Spirit: A Case Study of Hefei City DOI:  https://doi.org/10.30564/jgr.v5i3.4788 Abstract City spirit is the soul of the city. The spread of city spirit not only could establish a civilized specimen for citizens, but also create a good cultural atmosphere for the city. Hefei residents’ perception of city spirit is extensive, and most of Hefei citizens consider the expression words of city spirit are very appropriate, which is enlightened, open-minded, actual and innovate. Great majority of Hefei citizens willing to support the propaganda and promotion of the city spirit, and they think the promotion of the city spirit plays a key role in the way of city’s development. In addition,significant differences in the perception of urban spirituality emerge among residents with different economic and social characteristics. There are four aspects about how to enhance the public perception of city spirit, which including in...
