how to make a rectangular area of longitude and latitude
coordinates that enables to cut away the area not needed in other layers?
In QGIS 2.2 (and just about any GIS that has geoprocessing tools) there are
two ways to extract data.
The first is to clip the data from the existing file using
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?

Marcus,
I think what you are asking is can you just view the area that you are
working on and have QGIS hide or filter out those feature not within the
area of concern.
From my understanding is no. Well not exactly.
My understanding is that shapefiles will allways be processed regardless
Hello Marcus,
The feature I believe you are describing is being worked by a few
developer, have a look in this pull request:
https://github.com/qgis/QGIS/pull/1254
Maybe it lands in QGIS 2.4 :)

I usually make a new vector Layer. Then you can draw or use the
numerical vector editor to add a polygon. This polygon can then be used
as a clipping mask. Simply having a layer of a given extent isn't
enough, you have to have a polygon object in the layer.
As for why this isn't the way it
