From download Landsat images to NDVI (step by step)

Recommended Posts

Dear all,

sorry if this topic exist here...

I have a few question:

I have downloaded three Landsat images (L1TP) because my study area is very big, there is overlapping between images. I would like to make NDVI for that area, and I am interested what the steps are:

Do I need to do atmospheric correction first, then I have use copy raster tool to eliminate black NoData part of the images?....after that how to merge (join) images but to avoid lines because of overlapping. After that I guess I can make NDVI? 

Thank you all in advance :)

Ok thank you, and about atm. correction (in FLAASH) ? Should I do it on the separated images or on the mosaic?

 

Thank you very much?
