I have to use elevation data (dem.tif) and NDVI data (ndvi.tif) as covariates for regression kriging and I want both these files as txt files.
How do I do this?
Simply use the (Raster to ASCII) tool.
ArcTool Box go Conversion > From Raster > Raster to ASCII
Then locate your input raster and click on output location, then under Save as Type select second option "File".
