How to remove unwanted parts of a bigger map that is outside the smaller map above it?

Question

This is what I'm working on:

How can I remove the parts of the land cover map that is outside the Baao map?

I can't use the filter function since the land cover map does not have location data:

Answer 1

For the Land cover layer, right-click and go to Properties > Symbology. In the Layer Rendering section at the bottom, set the blending mode for Layer to Overlay and the blending mode for Feature to Normal. Apply and make sure the Land cover layer is above the Baoo layer in the Table of Contents.

This will only render the land cover which overlays the Baoo layer.

Note that this is only for display purposes. If you want to create a new layer which geometrically cuts the outer map, you can use the Clip tool.

Answer 2

@Joseph is right. Here's how I did it (there's an error that others might encounter too).

1. Use Vector > Geoprocessing Tools > Clip
2. An error showed after running the tool. It said there is an invalid geometry and I should change the Processing setting to "Ignore invalid input features'option." See this Ignoring invalid input features with Intersection tool in QGIS?
3. I did the suggested solution but error again. So, instead of "Ignore...", I picked "Do not filter." This is in Settings > Options > Processing > General > Invalid Features Filtering."
4. I also used the "Check Validity" tool for both layers. You will get a Valid, Invalid, and an Error layer for both layer. Vector > Geometry Tools > Check Validity
5. I now used the Clip tool using both of the Valid layers and done.
