Pada daerah yang luas biasanya terdapat kesulitan dalam memantau fase tumbuh tanaman padi. Seiring dengan berkembangnya teknologi, salah satu alternatif dapat dilakukan untuk memperoleh data tersebut adalah menggunakan citra satelit. Fase padi diketahui menghitung indeks vegetasi berdasarkan tingkat kehijauan bantuan MODIS algoritma NDVI. Tujuan dari penelitian ini menentukan persamaan dan rent...

Aim Theoretical, experimental and observational studies have shown that biodiversity–ecosystem functioning (BEF) relationships are influenced by functional community structure through two mutually non-exclusive mechanisms: (1) the dominance effect (which relates to traits of dominant species); (2) niche partitioning [which diversity (FD)]. Although both mechanisms been studied in plant communit...

The aim of this research is to provide a detailed characterization of spatial patterns and temporal trends in the regional and local dust source areas within the desert of the Alashan Prefecture (Inner Mongolia, China). This problem was approached through multi-scale remote sensing analysis of vegetation changes. The primary requirements for this regional analysis are high spatial and spectral ...

This paper aims to present an integrated approach for assessing the desertification processes on one hand and spot possible source locations of dust storm in Eurasian continent across the central Asia and northern China on the other hand. The authors have bu ilt Remote Sensing Environmental Monitor (RSEM) for Desertification Assessment System (DAS). Such an integrated sensing, monitoring and mo...

in this article, new index, the optimized synthetized drought index (osdi), is suggested for real-time monitoring of this phenomenon in areas with heterogeneous land covers. the precipitation, one of the important factors in drought, measured by ground stations and improved bytrmm satellite data. each of the three normalized moisture indices, including normalized difference vegetation index (nd...

Forest’s ecosystem is one of the most important carbon sink of the terrestrial ecosystem. Remote sensing technology provides robust techniques to estimate biomass and solve challenges in forest resource assessment. The present study explored the potential of Sentinel-2 bands to estimate biomass and comparatively analyzed of red-edge band based and broadband derived vegetation indices. Broadband...

This paper reports the passive microwave radiometry application for regional assessment of crop growth in India. Brightness temperature (TB) of various vegetation classes observed at 37 GHz using special sensor microwave imager (SSMI) data. during Kharif season in 1 999 in India are analyzed. Vertical as well as hQrizontal polarization brightness temperature is used to derive microwave polariza...
