The landsat archive has several images for each of the 12 months in a year, do I choose only one preferred image or I need all of them.
Hi Sadat,
You can download the raw radiance image. You should have one image for each month of the year. You can do the atmosheperic correction using Qgis. You can then go ahead with your LULC classification (using different landsat bands combination).
However, you should be careful of cloud covers especially during the wet seasons,
Having some ground data of landuse classes could give you more accurate classifications. Then you can also do your accuracy assessment.
Hey there!
If you want to do LULC classification, download the suitable image of particular day preferably having 0% cloud cover. After hitting on download you will be given 5 option of the image that you can download. choose the last image download option. The files will be in zip folder containing tif extensions and will be the heaviest file.
Read about the band combinations before you layer stack images and jump into the classification. Usually 2,3,4,5 bands of landsat 8 (OLI) and 1, 2, 3, 4 bands of TM or ETM+ are used for making standard FCC images for classification.
Good luck!
