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.
