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".

  • Thanks Moh. Could you please also clarify me to use elevation from dem and NDVI as covariates 1. Do I need to project them first 2. Do I need to resample them to same cell size before converting them to txt file – Ahmed Shabir Jul 13 '18 at 18:54
