I hope somebody can help me.
At first I have merge some vectorlayers (lineshape) without problems. Then I've create a bounding box with "polygon from layer extend" (polygon-shape) without problems too.
And then when I tried to "extract by location", I always get the following error (screenshot).
At first i've thought the reason would be the large nummer of datasets (>3 million), but i get the same error with fewer datasets. Now i THink the problem is because of the merging tool, perhaps. But I can't imagine.
