[Qgis-user] How to get rid of the rest of the World?

[kmgkmgkmgkmg .]

Hello everyone..

I will be going on a little bit here now..

Wonder how to create a clip/mask layer or do something to the same effect?
More specifically, how to make a rectangular area of longitude and latitude
coordinates that enables to cut away the area not needed in other layers?

Since stuck with a quarter of the World or even the entire World in my
little project. This question is for shape file layers mostly, have not
gotten to the .tiff yet. They are not global though larger then needed. So
a universal solution for both types would be nice.

Is there a python console command to do this?
Is there a plugin to do this?
Is there a online service to create such a layer?
Is it possible from within QGIS?

Have tried the make a rectangle plugin, it cuts out zero features.
Also tried clipping with a layer of not the right shape and it says that
they do not have the right projection, even though it looks as they do, and
end up with a blank layer.

Sure plenty people have this problem, though the forums do not have any
clear explanations as I found nothing that really explains, even youtube
got one but that is for regional borders.

Is there some way of just knocking in the longitude and latitude to do this?
Please assist. Do not get why this should be so difficult.

Why does not QGIS ask first thing which area of the planet you wish to work
on a project? And then just filter out it automatically when you load layer
that include more than that? Perhaps this could be a feature of a future
release?

With hopes for many answers and simple solutions. I repeat just want a
specified area that easily can be determined by longitude and latitude
coordinates.

Yours hopefully..
Marcus
