Mapping Rice Seasonality in the Mekong Delta with Multi-Year Envisat ASAR WSM Data

Mapping Rice Seasonality in the Mekong Delta with Multi-Year Envisat ASAR WSM Data

Rice is the most important food crop in Asia, and the timely mapping and monitoring of paddy rice fields subsequently emerged as an important task in the context of food security and modelling of greenhouse gas emissions. Rice growth has a distinct influence on Synthetic Aperture Radar (SAR) backscatter images, and time-series analysis of C-band images has been successfully employed to map rice...

Flood Mapping and Flood Dynamics of the Mekong Delta: ENVISAT-ASAR-WSM Based Time Series Analyses

Satellite remote sensing is a valuable tool for monitoring flooding. Microwave sensors are especially appropriate instruments, as they allow the differentiation of inundated from non-inundated areas, regardless of levels of solar illumination or frequency of cloud cover in regions experiencing substantial rainy seasons. In the current study we present the longest synthetic aperture radar-based ...

Use of ENVISAT/ASAR wide-swath data for timely rice fields mapping in the Mekong River Delta

Rice Monitoring Using ENVISAT ASAR Data: Preliminary Results of a Case Study in the Mekong River Delta, Vietnam

ABSTRACT: Vietnam is one of the world’s largest rice exporting countries, and the fertile Mekong River Delta at the southern tip of Vietnam accounts for more than half of the country’s rice production. Unfortunately, a large part of rice crop growing time coincides with a rainy season, resulting in a limited number of cloud-free optical remote sensing images for rice monitoring. Synthetic apert...

Mapping of Agricultural Activities Using Multi-temporal Asar Envisat Data

Space borne radar data facilitates continuous monitoring of almost any location on the earth (limitations in polar zones) at quite low costs. Almost weather-independent operation of radar systems enables a reliable and continuous record of data from earth’s surface. In the framework of an ESA pilot project (AO335), ENVISAT polarimetric SAR data of year 2004 are examined for their usefulness in ...
