摘要
The present invention relates to a method for producing a surface temperature map using Landsat satellite images, and more specifically, (a) acquiring an image of a multi-wavelength band from a Landsat satellite (S101) (S102); (b) converting the multi-wavelength band image into a radiance value image through an algorithm for obtaining a radiance (S203), and Kelvin temperature through an algorithm (S204) for obtaining an absolute temperature of the converted radiance value image; Converting to a value image (S205), and generating a Celsius temperature image material (S207) through an algorithm (S206) for obtaining a Celsius temperature from the converted Kelvin temperature value image; (c) converting the Celsius temperature image data S401 into a vector isotherm S403 having a temperature property through an algorithm S402 for converting the raster into a vector, and Determining the generalized isotherm data through the generalization process (S404) from the isotherm (S406); And (d) applying a map schematic specification to the determined isotherm data (S407) to generate a surface temperature map.;The surface temperature map using Landsat satellite image according to the present invention provides vast information on the surface characteristics and temperature distribution, and the cause of temperature distribution on the surface using visual data and surface data captured at the same time is explained in detail through visual information. As a result, the scope of utilization of the land is widened, which is useful for various land-related projects.;Landsat satellite, land use, thermal band (10.4 ~ 12.5㎛), vectorize, spline, temperature map
