Question

7. Explain, in your own words with examples, what is selected using the functions “Intersect the source layer” and “Are within the source layer feature” when the source is a line and then a polygon feature (2pts)

Answer 1

Intersect the source function:-

The Source layer is the layer that is used to determine the selection based on its topological relationship to the target.

Intersect is the most generic operator. As its name implies, it will return any feature that geometrically shares a common part with the source feature (or features).
There are a few other operators that are equivalent to intersect for specific uses, for instance:

• Are identical to, when comparing point features
• Are within a distance of, when specifying no buffer or a buffer of zero.

Are within the source layer features:-This method differs from the Are completely within method in that the geometry of the target feature must fall inside the geometry of the source feature including its boundaries.
