I am trying to split the Hansen dataset https://developers.google.com/earth-engine/datasets/catalog/UMD_hansen_global_forest_change_2018_v1_6?hl=fr into 250x250 pixel tiles within a region.

For that I think I can use image.clip(geometry), but I am not sure how I can split a region in rectangles (how to map the rectangle coordinates to the pixels) so that each of them have the desired 250x250 pixel size.

    Hi Mr. Liu, what have you tried so far? include some code. What is your final goal?

  • gis.stackexchange.com/questions/315541/… . You possibly want to use neighborhoodToArray(KERNEL)

  • @RodrigoE.Principe I'm trying to get a bunch of 250x250 pixel tiles, 30m per pixel, from the Hansen Data within a specific region. I plan to feed those tiles to Tensorflow. I tried to use image.clip(geometry) but that normally requires some sort of Geometry, so I'm not sure how to proceed.

  • @Kuik could you explain a bit how neighborhoodToArray(KERNEL) works? I'm not sure if I understand it propertly. Does it store in every pixel, a matrix with the values of the neighbors up to the size of the kernel, being that pixel the center of the matrix?
