Abstract

<p>Land cover changes since 2000 in the vicinity of Tomsk City, West Siberia, were determined using Google Earth Engine.</p><p>Normalized vegetation indices, normalized water indices, normalized snow indices, and normalized soil indices were calculated from satellite images of the target area acquired by Landsat 5, 7, and 8.</p><p>In addition, slope, plan curvature, profile curvature, watershed area, topographic flatness, sediment transport index, and wetness index were calculated from DEMs acquired by SRTM.</p><p>The land condition polygon data around the year 2000 was used to create the teacher data, and the classifier of the land cover in the 2000s was created by random forest.</p><p>We used this classifier to classify the satellite images of the 2010s and 2020s, and calculated the change in land cover classification.</p><p>The results showed that the land cover change due to human influence was large in the decade from 2000s to 2010s, while the land cover change in the decade from 2010s to 2020s was small compared to the decade from 2000s.</p>
