- ItemAccuracy Assessment of The Urban Land Surface Temperature Calculation Based on Landsat-8/Oli Data (Case Study: Coyhaique, Chile)(IEEE, 2019) Verichev, Konstantin; Mikhaylyukova, Polina; Salimova, Alisa; Salazar, Cristian; Carpio Martínez, ManuelThe relationship between the values of the surface temperature retrieved from the Landsat-8/OLI satellite data and the values of the atmospheric temperature measured by NETAMO sensors in the urban environment of the Coyhaique city (Oct.2017Sep.2018) was analyzed.Based on the five satellite (one winter, one spring and three summer) images, the coefficient of the linear relationship determination between the two types of temperature was 0.85.
- ItemDynamics of Built-Up Areas over The Past 30 Years According to Remote Sensing Data in the City of Valdivia, Chile(IEEE, 2018) Verichev, Konstantin; Mikhaylyukova, Polina; Salazar, Cristian; Carpio Martínez, ManuelThe dynamics of built-up areas over the last 30 years in the city of Valdivia was analyzed according to Landsat satellite imagery data. For ETM+/Landsat-7 and OLI/Landsat-8 instrumentation systems, method of automatic satellite image interpretation of build-up areas showed inaccuracy, less than 1%, compared to visual method. For TM/Landsat-5 instrumentation system, method of automatic satellite image interpretation of build-up areas demonstrated unsatisfactory results. Since 1987 and by the year 2017 the city's built-up areas increased by 61% with the population growth of 66% within the same time period.
- ItemMapping of built-up area dynamics over the past 30 years in the princial cities of southern Chile based on Landsat Imagery(Bulgarian Cartographic Association, 2018) Verichev, Konstantin; Mikhaylyukova, Polina; Salimova, Alisa; Salazar-Concha, Cristian; Carpio Martínez, ManuelIn this paper, the dynamics of built-up areas over the past 30 years in principal cities (the actual population of more than 100,000 people) in southern Chile is analyzed according to Landsat satellite imagery data. The area of built-up territories increased by 244% in Puerto Montt, and the lowest by 14% in Punta Arenas, and in the same time period, the population in cities grew by 151% and by 28%, respectively. It was revealed, that given differences depend on the geographical, economic and administrative status of cities in the region of our study.
