Really like your work!

i was able to reproduce this! After almost 1hour rendering on a Ryzen 5600x 326g DDR4 ram 3600mhz, i was able to achieve the portugal map.png image on the directory. Also, i was able to watch the whole rendering process. It was amazing! Do amazon rainforest buddy! We brazilians, want to know how the situation is over here with illegal harvesting happening all the time!

Great work Sir Milos.. I am greatly inspired with this..
-
Amazing. make one tutorial for river please
-
good figure❤❤❤
-
Nice work. Which code editor is this?
-
My computer literally explodes with that render
-
Hi Milos. I like the editor you are using in this video. Is it Sublime Text? The arguments visualising is pretty helpful, which I don’t find in Rstudio.
-
First of all thenk you for the wonderful tutorial. But I didn't find any map with tiles from where I can download geotiffs. The linh "cloud optimized geotiffs here" is taking me in the another page. So, it would be very nice if you can help me regarding this matter.
-
Very nice video! Unfortunately, the link to download the cloud optimized geotiffs seems to be offline/not working. Waiting for it to work and try out your awesome tutorial!
-
Hi, Milos. I am geting stuck in section 3 (cropping tiles). This part of the code stops showing the next error: Error: [crop] file exists. You can use 'overwrite=TRUE' to overwrite it. If I add this statement to crop function, it works correctly but it doesn't crop properly. Is there any solution to this? The .tiff files are already in the same working folder
-
Great turotial thank you very much. I have also an issue, when I run the classInt: classIntervals, It takes ages to run and never run it. I chose a different study area and I put n = 5 so the dimensions are 1149, 2893 (smaller than the video) but it still do nothing. Is it normal? should I leave it to run ?
