I need to add to QGIS more than 3000 rasters tif (with pyramids). It works very hard and slowly. So I ask: There's a solution that give's them quickly?.

    This sounds like a lot of data for QGIS to manage. What are you trying to achieve? Perhaps you could do this outside of QGIS and then just load the product in

  • I'm surprised you could even load that many into a graphical map without crashing the thing. Kudos to QGIS for some good implementation there.

  • Hello Nathan. Thanks for answer!... I have a lot of raster with high resolution to enter into a library. I found solution to build by grouping the rastres in many vrt files. I think there's another better solution. what do you mean about: "do this outside of QGIS and then just load the product in"... I tryed to create a qlr file with all the rasters(almost 3000) but it crashed. May 10, 2018 at 14:05
  • Im curious as to what you want to do with the data once its in QGIS. For example, if you wanted to load them in so you could mosaic them, I would recommend doing this outside of QGIS first

You may see considerable benefit if you load them into a single virtual raster (vrt). You can do that through the processing toolbox, by searching for "build vrt"
