Im using the Copy Raster tool and its setting the null values to -999.
Copy raster in r full#
with r: To create a full copy of a map layer, use the g.copy module. 09:01:19,283 - Raster band is not byte, short, int, float, double.
I was able to reproduce your problem and solve it by changing the order of the process. Created overview is stored in the database and is not affected by -R. use the command g.list to list available raster, vector and site map layers. x, y is the position of the pixel and r,g,b are the Python.
I think that this is occuring because you are changing the resolution before changeing the extent, because this, the extent is bound by the resolution that you have assigned to it.

I tried to copy the metadata using: res(af1_area) <- res(af1_patch)īut it doesn't work, dimensions and resolution are incorrect and the data values are lost: af1_areaĭimensions : 166, 166, 27556 (nrow, ncol, ncell)Įrror in.

I tried to use raster, because I made all the processing in R. I know that all the metadata information was exactly the same so I want to copy it from one file to the other. I have two geotiff raster files, one has all the metadata information and in the other the metadata information was lost.
