The development of UAV-based sensing systems for agronomic applications serves the improvement of crop management. The latter is in the focus of precision agriculture which intends to optimize yield, ...
HJ-1A/B NDVI (HJ NDVI) time-series data possess relatively high spatio-temporal resolution which is significant for the research on urban areas. However, its application is hindered by noise resulting...
TUBITAK UZAY has conducted a research study on the use of space-based satellite resources for several aspects of agriculture. Especially, there are two precision agriculture related projects: HASSAS (...
The El Niflo Southern Oscillation (ENSO) phenomenon produces an important inter-annual variability of oceanic and atmospheric conditions with irregular periods and amplitudes in many regions of the wo...
Vegetation coverage change is a very important indication of the ecological enviroment change. In this paper, we detected the vegetation cover change by retrieving the fraction of the vegetation cover...
Multiple cropping system, characterized by cropping index, is of significant importance to Chinese food production and security.Owing to the changing nature conditions and human activity, cropping ind...
The article, using the each ten day’s data of NOAA/AVHRR from 1981 to 2000 and adopting the Maximum-Slope Method and Curve-Fitting Method, analyzes the beginning and ending of the growth season of the...
One of the possibilities offered to us by the remote sensing, is to monitor all the vegetation. Therefore agricultural plants can be monitor as well. From the spectral point of view, the presence of v...
Spatial relationship between vegetation and rainfall in Central Kazakhstan has been modelled using Normalized Difference Vegetation Index (NDVI) and rainfall data from weather stations. The modelling ...
Background and data: Alpine environments are particularly sensitive to climate change such as changes in snow cover. An important instrumentation to detect and monitor snow cover extent and duration...
This work modelled the spatial distribution of the rodent species that act as hosts in the transmission cycle of the parasitic tapeworm Echinococcus multilocularis. The rodent distribution was modell...
To evaluate accuracy of low resolution vegetation mapping for hydrological purposes, a comparative study of NDVI images derived from MODIS and Landsat 7 ETM+ data has been done. Main goal is to unders...
Potential evapotranspiration (PET) is an important parameter of water budgets at different spatial scales and is a critical variable for understanding regional biological processes. It is often an i...
The spatial relationship between vegetation patterns and rainfall as well as its trend over the period 1985-2000 in the shrubland, grassland, and cropland of the Middle Kazakhstan was investigated wi...
Plant phenology is an integraph of global changes and a comprehensive indicator of landscape and entironment changes, and its responses to global environment changes have become a focus of the field ...
