[Star Wars] Why did the trade federation form of a blockade of a singular line around the planet when ships can move in three dimensions?

Every blockade we see from the federation seems to be a cluster of ships surrounding the circumference of a planet but it usually in one line... So what if someone comes from "under" the planet. I know "under" is a relative term in regards to space travel but planets are huge. What if someone came out of hyperspace and the planet is directly above them as in, they are approaching from the southernmost point of the planet, would they just fly in undetectable to the trade federation?

It’s because when you come out of hyperspace you end up in a certain area. If the blockade is right in front then there is no real point of placing your ships vertically. It’s also why blockades in Star Wars rarely ever surround the whole planet.
