Atmospheric correction for Landsat 5 images by applying 6S modeling technique


1)    Data and materials

§ http://6s.ltdri.org/pages/run6SV.html

§ https://earthexplorer.usgs.gov/

§ Study area:Beijing, China

2)    6S model

§ applied to B1, B2, B3, B4, B5 and B7

§ ρo :0,0.25, 0.5, 0.7, 0.95

§ scatter plot and regression equations (see Fig.1)

Fig. 1 6S correctionfor Landsat’s 6 bands

3)    Code

§ Do the atmospheric correction by Google EarthEngine coding

§ Code link:

§ https://code.earthengine.google.com/3ba8add9eacddefff9c8738a3d91dcfd

§ In the exercise, I also tried to compare the differencebetween NDVI result using un-corrected images and NDVI result using 6S-correctedimages. However, there seems no difference.
