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 ...

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 ...

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.
