    Please create the
    Maps by modeling forest fre-vulnerability risk map using historical forest fre incidents based on MODIS data, using the a
    deep neural network (DNN) approach, and the Maximum Entropy (MaxEnt) approach. This same data was used to develop the graph of spatial
    distribution of burned area across diferent elevation zones and d burned area across four physiographic zones

    Thanks, Ramadhan for this very useful video. I checked your code and wondering if the Landsat 7 was used at all because the function specifying the images did not include L7. It only specified 4 & 5 and 8 & 9.

    Hi Ramadhan,great, your contribution to is very important, however, when executing the code in a different area, the following error appears:
    VI_2005: Layer error: Image.select: Pattern 'B7' did not match any bands.
    Forest_2005: Layer error: Image.select: Pattern 'B5' did not match any bands.
    Forest Year: Layer error: Image.select: Pattern 'B5' did not match any bands.
    Image.select: Pattern 'B5' did not match any bands.
    I think it may be due to some empty bands from the L8 or L5 collections, for new roi
    Any help will be useful, thank you very much for your contribution...
