03. Study on using SPOT-6 satellite images and construction design drawings to determine landslide points along the border patrol route in Son La province

Abstract

This study investigates the ability to identify landslide points from SPOT-6 optical satellite images combined with design drawings or as-built drawings of the route. The proposed method consists of two main stages, including: to classify the landcovers from optical satellite images using the fuzzy classification technique and to use design drawings or as-built drawings of the study route normalized to GIS data, then compare with the classification results to determine the landslide points. Experimental determination of landslide points along the border patrol route in Son La province was carried out by using SPOT-6 satellite image data taken on 28/3/2019. The results showed that the proposed method is accurate and can be used for rapid detection of landslide points.
