I would like to extend this example to extract values from a multi-band image. I am using the example linked to manually select the band and export each GLCM texture measure as a 2D table (w/ values from each scene ID in columns). I was hoping to run it as a single command (big thanks to Rodrigo Principe for the original answer). The solution can either write a file for each texture (in a loop) or export a single, really wide table.

I've pasted the tail end of the code below. please excuse all the extra comments, I'm still coming to grips with JavaScript. Any help appreciated. Cheers

I would like to extend this answer to Extracting pixel values by points and converting to table in Google Earth Engine? in order to extract values from a multi-band image.

I've tried placing the mapfunc function in a for loop, but can't seem to get it right. I've pasted the tail end of the code below. please excuse all the extra comments, I'm still coming to grips with JavaScript.

I've tried placing the mapfunc function in a for loop, but can't seem to get it right. I've also tried lopping the .get("VH_diss"); off the end of the value variable (this might be working but GEE takes ages to export even a small test subset- so unsure if this is the simple solution).
