I have an ArcGIS project with raster and vector layers. I use the function Export map ... to export layout view to a tiff file with different DPI values (150 and 300). The resulting image is very different from what is displayed in the ArcGIS. The resolution of the raster layer is highly distorted regardless of the DPI option.

How to fix this issue?

enter image description here Pic 1. ArcGIS layout view (natural raster layer resolution). enter image description here Pic 2. Export result - DPI 150 (raster layer resolution reduced). enter image description here Pic 3. Export result - DPI 300 (raster layer resolution reduced same way as with DPI 150).

  • Under the Format tab when you export, do you have any compression on your Tiff export? – Rex Feb 21 '18 at 14:17
  • @Rex Yes, LZW. But it is lossless compression. – Mr. Che Feb 22 '18 at 4:52

I would suggest bumping the DPI to 600, changing the file type to PNG format and changing the resample during display using to Bilinear Interpolation (for continuous data)

The problem was caused by the custom projection of the raster layer. Reprojecting raster data into a data frame projection solves the problem.
