I have been tasked to mosaic 26 DEM tiles together. In doing so, I have come across an issue where that last 3 DEMs become checkerboard (see attachment) at a scale beyond 1:150,000. Zooming in below 1:150,000 everything is fine (no checkerboard), which is weird. I used the "Mosaic To New Raster" to create this mosaic. Any ideas? Thank you, Daniel
