I have multiple elevation raster tiles of an archaeological site and it would be extremely useful for me to visualize the topography as one 'uniform' image/layer. I have attempted to merge the rasters, build a virtual raster, and copy/paste the style from one layer to others, yet I have been unable to produce a seamless image from any of the said methods.
The tiles overlap considerably, most more so than the two tiles in the example. I have checked the elevations between layers of some of the overlapping areas and they appear to match, so the problem doesn't seem to be incongruous elevation data.
When I have copy and pasted styles I have made sure to change the elevation data to the min/max values among the tiles and as well as make sure the break values also match. Yet, inconceivably, this makes it worse.
