Downloading SoilGrids v2 raster data

This repository contains R scripts for downloading SoilGrids v2 data. Since the original tutorials provided by ISRIC did not work for me, I made a web scrapping algorithm for downloading the data directly from their webmapping service.

  • script_making_tile_indices.R: defines a bounding box and tiles size (in this case I was able to make up to 10 degree of Lat and Long extent), which can be exported as a gpkg layer for local indexing. There is an edge buffer of around 0.01 degree for each tile.
  • script_soilGrids_download.R: downloads the SoilGrids data for different soil attributes and soil depths using the custom parameters.
  • script_debugging_with_thumbnails.R: for some reason (perhaps internet connection), some tiles are broken and cannot be visualized. Therefore, this script identifies the problematic tiles for redownloading.
  • script_overviews_and_virtual_rasters.R: overviews and mosaicking of tiles can be made from this script.
