Potential of Using Remote Sensing Data for Dike Inspection

Dikes are increasingly becoming structures of major importance in view of sea level changes. Dike inspectors monitor dikes visually whilst walking the dike. It has been proposed that remote sensing could be used to make dike inspection faster and cheaper. This paper presents the results of a study which investigates remote sensing for evaluating the soil moisture and dike grass cover quality. Correlations were found between soil moisture and thermal and multispectral remote sensing data, and between dike grass cover quality and multispectral remote sensing data. Remote sensing provides useful information for soil moisture and grass cover quality evaluation for dike inspection and may be useful for dike quality inspection.
