Emne: [R-sig-Geo] issue when opening raster image in R, the pixel values a rescaled somehow

I opened a Geotiff image in R using the raster function. However, the image seems to be rescaled. The minimum and maximum values should be 13607 and 15461 but are 275 and 305. The Geotiff image when opened in a GIS is correct but not in R. This is my code: Script: library(raster) trial<-raster("MOD11A2.A2000049.h17v05.006.2015058135048.tif", datatype = "INT2U") trial plot(trial) [[alternative HTML version deleted]] _______________________________________________ R-sig-Geo mailing list R-sig-Geo using r-project.org https://stat.ethz.ch/mailman/listinfo/r-sig-geo
