This research is investigating the above ground biomass mapping of mangrove forest in Vietnam by ALOS PALSAR measurements. Our test sites are located at four districts of Quang Ninh province in the Northeast of Vietnam. Firstly, a field measurement were carried out in to measure water level, tree species, height, diameter at breast height (DBH) and crown diameter. Secondly, Soil sampling will be further...
NOAA (National Oceanic and Atmospheric Administration) satellite images have been widely used for environmental and land cover monitoring. This paper proposes a geometric correction method that corrects the geometric distortions in NOAA images. In this method, the errors in NOAA images are corrected in the image coordinate system before transforming into the map coordinate system. First, the variation...
NOAA (National Oceanic and Atmospheric Administration) satellite images have been widely used in environmental and land cover monitoring. Before delivering to the consumers, NOAA images need to be accurately transformed from image into map. This paper proposes a geometric correction method that corrects the errors caused by this transformation. In this method, the errors are corrected in image coordinate...
This paper describes a high accurate geometric correction method for NOAA AVHRR data considering elevation effect. NOAA data in map coordinate system is divided into rough and flat blocks to identify the variation of elevation. GCP template matching and affine coefficients are then used to correct residual errors in image coordinate system. In order to correct more residual errors, appropriate flat...
