I have a large collection (>20000) of georeferenced satellite imagery tiles in TIFF format. Each of them has a size of 64x64 pixels.

enter image description here

Is there a way to extract the lat/lon coordinates of the midpoint of each tile and store them all in one table?

I have never tried this for such a huge amount of rasters; hope this works:

  1. GDALTileIndex (Raster > Miscellaneous > Tile Index) on your raster
  2. Centroids (Vector > Geometry Tools > Centroids) on the tile polygons (from Step 1)
  3. Add Geometry Attributes (Processing Toolbox > Vector geometry) on the centroids (from Step 2)
