The Use of Modis Data to Derive Acreage Estimations: a Case Study in Rostov Region of Russia
نویسندگان
چکیده
The recent developments of remote sensing technology, in particular with its improved spatial and temporal resolution, open new possibilities for estimating crop acreage over larger areas. Remotely sensed data allow the estimation of crop acreage independently of sometimes biased and incomplete sub-national survey statistics. This paper presents a methodology on crop acreage estimations using the MODIS13 16-day composite NDVI product. The suitability of the different MODIS products for acreage estimations is assessed. Particular emphasis is placed on a good quality crop mask. Preliminary results for winter crop area estimates are presented.

The Use of Modis Data in Southern Russia for Crop Acreage Estimations and Inter-comparison of Results from Various Crop Acreage Estimation Methods
The first part of this paper presents a methodology on crop acreage estimations using the MODIS 16-day composite NDVI product. Particular emphasis is placed on a good quality crop mask and a good quality validation dataset. A novel approach which is based on the sampling of pure fields has been developed. The novel approach has been tested in previous work using a traditional maximum likelihood...
متن کاملCanine and Human Dirofilariosis in the Rostov Region (Southern Russia)
Epidemiological data on canine and human dirofilariosis in the Rostov Region (Southern Russia) are presented. Prevalence of Dirofilaria spp. infections in 795 autochthonous dogs, assessed by the Knott test, was 20.25%. The highest prevalence was found in Novocherkassk (38.3%) and Rostov-on-Don (18.5%), while prevalences were lower in other points of the region. Prevalence of D. repens was 44.7%...
متن کاملDrought Monitoring Using Vegetation Indices and MODIS Data (Case Study: Isfahan Province, Iran)
Drought is a major problematic phenomenon mostly for semi-arid areas of Iran. During drought periods, reduction in vegetation levels causes such problems as soil erosion, surface runoff, flood risk, etc. Therefore, the assessment of drought effects on plant covers is the most important issue. This research was conducted in 2015 using the extracted vegetation indices from Moderate Resolution Ima...
متن کاملDrought monitoring using MODIS data and its comparison with SPI meteorological index in short periods (Case study: Jaz_Murian basin)
Drought is one of the most important threats for agricultural production in the world, espatially in Iran. This phenomenon has started with reduction of precipitations that lead to a decrease in soil moisture and an increase in soil surface temperature, which affect the vegetation growth. The purpose of this study was to investigate droughts in the Jaz_Murian basin by VHI, VCI, TCI and SPI indi...
