I downloaded many .hgt files to map California. When I open them in QGIS, the borders line up perfectly, but the average height shading is different for each .hgt file. Is there a way to average out the height data so every file's elevation lines up and the heights are parsed the same way when exporting the full map? It seems like adding a reference min and max height would do the job.enter image description here

  • You somehow had given the answer :you could easily have set all tiles Style to have the same (global) min & max values for the grayshade

Build a virtual raster and all the tiles will be treated/symbolized as one:
