Integrating Remote Sensing and Meteorological Data to Predict Wheat Stripe Rust

open access: yesRemote Sensing, 2022
Wheat stripe rust poses a serious threat to wheat production. An effective prediction method is important for food security. In this study, we developed a prediction model for wheat stripe rust based on vegetation indices and meteorological features ...

Analysis of the LST and Vegetation Indices relationship using Landsat-8 data in Duhok Governorate, Iraq

open access: yesAl-Mustansiriyah Journal of Science, 2021
Vegetation cover is considered one of the most important factors that affect weather, climate, and the environment. This paper aims to study the correlation between land surface temperature and the Vegetation Indices using Landsat data in Duhok ...

MODISTools - downloading and processing MODIS remotely sensed data in R [PDF]

open access: yes, 2014
Remotely sensed data – available at medium to high resolution across global spatial and temporal scales – are a valuable resource for ecologists. In particular, products from NASA's MODerate-resolution Imaging Spectroradiometer (MODIS), providing twice ...

Identification of Forest Vegetation Using Vegetation Indices

open access: yesChinese Journal of Population Resources and Environment, 2004
Abstract Spectral feature of forest vegetation with remote sensing techniques is the research topic all over the world, because forest plays an important role in human beings' living environment. Research on vegetation classification with vegetation index is still very little recently.

Evaluation of pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment with landsat thematic mapper [PDF]

open access: yes, 2011
In this study several pre/post-fire differenced spectral indices for assessing burn severity in a Mediterranean environment are evaluated. GeoCBI (Geo Composite Burn Index) field data of burn severity were correlated with remotely sensed measures, based ...

Detection of irrigation inhomogeneities in an olive grove using the NDRE vegetation index obtained from UAV images [PDF]

open access: yes, 2019
We have developed a simple photogrammetric method to identify heterogeneous areas of irrigated olive groves and vineyard crops using a commercial multispectral camera mounted on an unmanned aerial vehicle (UAV).

Temporal Variation in Vegetation Indexes for Pine and Beech Stands During the Vegetation Season, Szczecin Lowland, Poland

open access: yesQuaestiones Geographicae, 2014
Located in north-western Poland, the Bukowska Forest and Goleniowska Forest are vast woodlands consisting of areas with a homogeneous species composition that have been scarcely affected by humans.

Comparison the accuracies of different spectral indices for estimation of vegetation cover fraction in sparse vegetated areas

open access: yesEgyptian Journal of Remote Sensing and Space Sciences, 2011
Quantitative estimation of canopy biophysical variables are very important in different studies such as meteorology, agriculture and ecology, so knowledge of the spatial and temporal distribution of these variables would be highly beneficial.

Vegetation response to extreme climate events on the Mongolian Plateau from 2000 to 2010 [PDF]

open access: yes, 2013
Climate change has led to more frequent extreme winters (aka, dzud) and summer droughts on the Mongolian Plateau during the last decade. Among these events, the 2000–2002 combined summer drought–dzud and 2010 dzud were the most severe on vegetation.
