Research on extracting suspended particle matter content (SPM) based VNRedSat-1 imagery for monitoring water quality

Abstract

Currently, VNREDSAT 1 data have been commonly applied in studying disciplines of landscapes or socioeconomy. Nevertheless, there are limited studies using these data in water quality management. This article focuses on estimating amounts of SPM (Suspended Particulate Matters) from VNREDSAT 1 in Thi Vai river basin based on a popular formula with on - site adjustments. Results were validated by field data with an relative value R2 = 0. 79. This value represents that there is a potential of applying VNREDSAT 1 in studying SPM in water depending on certain circumstances of accuracy.
