Advancements in Estimating Crop Growth Stages Using Radarsat-2 and Terrasar-x Polarimetric Data
This paper uses RADARSAT-2 quad Polarimetric Synthetic Aperture Radar (PolSAR) and TerraSAR-X dual polarimetric SAR data to monitor agriculture crop growth stages. Two RADARSAT-2 Fine Quad Wide (FQW) beam modes FQ2W and FQ10W, each with 5 sets of data and 13 sets of Stripmap TerraSAR-X data were used in the study. Both RADARSAT-2 POLSAR data and TerraSARX data were acquired in summer 2012 outsi...
متن کاملEstimating Surface Soil Moisture Using Radarsat-2
Extremes in soil moisture, either too much or too little, present a significant risk to agricultural productivity. Managing and mitigating risk requires information and knowledge to assess risk potential, implement risk reduction strategies and deliver responses to this risk. Synthetic aperture radars (SARs) are sensitive to the dielectric properties of soils and are thus well suited to provide...
متن کاملModeling Crop Water Productivity Using a Coupled SWAT–MODSIM Model
This study examines the water productivity of irrigated wheat and maize yields in Karkheh River Basin (KRB) in the semi-arid region of Iran using a coupled modeling approach consisting of the hydrological model (SWAT) and the river basin water allocation model (MODSIM). Dynamic irrigation requirements instead of constant time series of demand were considered. As the cereal production of KRB pla...
متن کاملA processing and software system for rice crop inventory using multi-date RADARSAT ScanSAR data
An operational crop survey program requires standardised procedures and software packages to meet the specified targets Ž . of timeliness and accuracy of estimates. Currently, the focus is to include Synthetic Aperture Radar SAR data in such a program, as these data are available from a number of sensors. A procedure has been developed to use multi-date SAR data for rice crop inventory. The ste...
متن کاملOperational Surface Water Detection and Monitoring Using Radarsat 2
Traditional on-site methods for mapping and monitoring surface water extent are prohibitively expensive at a national scale within Canada. Despite successful cost-sharing programs between the provinces and the federal government, an extensive number of water features within the country remain unmonitored. Particularly difficult to monitor are the potholes in the Canadian Prairie region, most of...
