Assuming you have several 100 000 files on your discs
- which are all georeferenced
- which are all readable within QGIS (Raster maps, sqlite maps, vector maps, shapefile etc.)
After 20+ years in working with geodata I lost the overview over my collection.
In consumer tools like Oziexplorer or Oruxmaps you have a feature where you can see the outline of available datasets at your region of interest. If you click on this outline, the data is loaded.
Is there a tool like this in QGIS, maybe a plugin, and able to handle 100 000++ of datasets?
