Hi, A raster database has not been developed yet in QGIS, unless it was recently add and don’t know about it. I did not know it could stored in the metadata. I know some metadata (Like layer name, file name) can queried as variables. Could this be used in a python script? Anyone???
Ultimately, you could do a raster to vector conversion and add the data in a new database. You could make that layer transparent but still access the dataset.
