So I'm using this VGIN data to understand land cover surrounding points in Virginia in QGIS. The VGIN data came with ~100 tiles (and for each there is a .tif, .tif.ovr, and .tif.vat.dbf file) and two .xml files, one of which contains the land use classifications at specific values, along with other metadata.

I am 100% self-taught on QGIS and pretty much GIS entirely. Is there a way to be using these files in tandem so that when I pull a tile into my project it will have those classifications per-categorized, or do I have to do that with each tile?

The VGIN data would be SUPER useful, if only I could wrangle it! I'd be happy to have this be a Python learning opportunity, but don't want to overcomplicate if I don't have to!


  • Build virtual raster of tiles, then do the classification once. – user2856 Sep 16 '20 at 9:13
  • @user2856 I just tried, but ended up with a large black square rather than a nice mosaic of my tiles... – Ben Rhoades Sep 17 '20 at 19:31

I was able to build a .vrt virtual raster with the necessary tiles, and then manually entered the classification from provided metadata! The first time I had tried, I ran into issues, but I hit the "ignore projection differences" button and that worked... Probably not the best solution, but I have land use data that overlays with my other data points now so i'm not complaining
