R：“光栅”无法读取“readGDAL”能够读取的 GeoTIFF

Question

Question :

I'm working with MODIS GeoTIFFs. I want to use the sf and raster libraries. The file easily opens with rgdal::readGDAL() , which gives me an object of type Large SpatialGridDataFrame . So the file is not corrupt.

Yet, if I use raster I get the following error:

raster::raster("../MCD64A1/TIFF/Win09/2014/MCD64monthly.A2014001.Win09.006.burndate.tif")
  Error in .rasterObjectFromFile(x, band = band, objecttype = "RasterLayer",  : 
  Cannot create a RasterLayer object from this file.

More background info :

The same happens if I use raster::stack .

For reproduction: the file can be found in the MODIS -collection or be directly downloaded here . Relevant package versions are:

 [1] raster_3.4-13 rgeos_0.5-8   sf_0.9-8      rgdal_1.5-27  sp_1.4-2      RNetCDF_2.5-2

Edit :

It seems raster hides some error message. Calling the internal .rasterFromGDAP directly reveals the error message. Though the fix remains unclear:

> raster:::.rasterFromGDAL("../MCD64A1/TIFF/Win09/2014
/MCD64monthly.A2014001.Win09.006.burndate.tif", type = "RasterLayer",band=1)

Answer 1

I do not get this error.

I think it will go away for you as well after you update the sp package. When things do not work, it is good practice to first assure you have the latest versions of the R packages (perhaps run update.packages(ask=FALSE) )
