Hey, do you want to map deforestation in your area over multiple years in a simple way instantly? Don't worry I just create a script to make it easy and fast as possible.
Script: code.earthengi...
In this video, I will show you how to create a simple deforestation map using Landsat multi-temporal imagery from 1990 - 2020 with 5 years intervals. All of this is done in Google Earth Engine, making it easy to composite the imagery and analyze it.
I'm using almost the same script with the river change and urban sprawl. The area that I am using is Palangkaraya City, Central Kalimantan where deforestation is quite alarming.
I hope that my video could help you to generate a deforestation map for your research and project area.

Error generating chart: Error in map(ID=0): Image.reduceRegion: Too many pixels in the region. Found 11175761, but maxPixels allows only 10000000. Ensure that you are not aggregating at a higher resolution than you intended; that is a frequent cause of this error. If not, then you may set the? can you resolve it?

Error generating chart: Image.select: Band pattern 'B5' was applied to an Image with no bands. Forest_2005: Layer error: Image.select: Band pattern 'B7' was applied to an Image with no bands. VI_2005: Layer error: Image.select: Band pattern 'B5' was applied to an Image with no bands. Image.select: Band pattern 'B5' was applied to an Image with no bands. Forest Year: Layer error: Image.select: Band pattern 'B5' was applied to an Image with no bands. S These errors came when i changed the roi to a shapefile of a city

Add maxPixels: 1e13 argument

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

@ramiqcom Год назад

I suggest you study more about that

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.

@ramiqcom 10 месяцев назад

yeah, it is becuase of the stripped error of the landsat 7

Thank you for your kindness. It would be nice to write your code based on the definition of a shape file so that it can be used everywhere.

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...

@ramiqcom Год назад

I think your area might not have any image at that time period. Try another area
