Abstract
The article presents the results of the investigation of thermal field dynamics in the forest harvesting sites with the Landsat 8 satellite images in a long Infrared range. The temporary (annual and seasonal) dependences of the forest floor temperature in the harvesting sites are studied. The dependence of the forest floor temperature condition in the harvesting site on the area of the site is considered. The method to detect the sites strewn with the forest residues by using the images in a near Infrared range is described.
Highlights
Background valueThe calculated value of temperature difference between the mean temperature within the borders of the forest harvesting site and the background value of the temperature is shown in figure 1.In the first year of measurements the mean temperature difference between the forest harvesting site and surrounding background was 5,15 °C
This paper examines the features of thermal field dynamics for the forest harvesting sites obtained with the Landsat 8 spacecraft in a long Infrared range and the method of detecting the sites strewn with the forest residues by using the images in a near Infrared range
The thermal field dynamics was investigated in 22 forest harvesting sites of different area located within the borders of the test site
Summary
The thermal field dynamics was investigated in 22 forest harvesting sites of different area located within the borders of the test site. The minimum size of harvesting sites was 2,27 hectares, the maximum – 26,97 hectares. The research was conducted for the time period from 2014 to 2017. Sets of space images used for the research are presented in table 1
