Hi, this is a pretty basic question I think, excuse my inexperience.  Can anyone tell me how to select an area on a map and zoom to that area?  I want to either extract this area and create a separate raster layer or put borders round the area so that I know I have a specified area in km squared.  I have tried using the measurement tool but I cant work out how to then select the area I measure out.  Any help would be greatly appreciated.
