Overlay in QGIS

Hello everyone. how can i overlay a vector layer raster layer to come up with one reasonable map?

I can’t tell you how to do it in QGIS, there are other forums better suited. I can tell you how to do it in SNAP.

When you have opened your data, you can import vector data by selecting File / Import / Vector data from the menu.

You can define a geometry by WJT right-click on the image view and select Geometry from WKT

You can also add layer via the layer manager:
