%X This dataset uses the WGS84 coordinate system, and the file format of GMIE-100 is GeoTIFF. The GMIE-100 irrigation ratio is represented in a single band image. The pixel value of GMIE-100 corresponds to the irrigation ratio of the corresponding spatial grid, with a range of 0-1 and a background value of -99. For areas that require regular irrigation, the data was produced using the dry months from 2017 to 2019; For areas that occasionally require irrigation, the data was produced using the driest months from 2010 to 2019. There are a total of 67 tiles worldwide. If most of the tiles overlap with land, the maximum range is 21 ° x 21 °. Otherwise, the range will be adjusted according to the land range. The file is GMIE-100 log_lat.tif, where lat and log represent the rounding of the longitude and latitude of the center point. The tile field can be found in the file "tiles of GMIE-100. shp". GCPIS is stored in shapefiles format in a zip file.
