I'm using QGIS.
How can I create a shapefile consisting of a grid 0.5° latitude and 1° longitude in size?

use the MMQGIS plugin, after installing you find it in qgis 1.8 under plugins--mmqgis. select create --create grid layer and enter the appropriate values
for h spacing and v spacing select 1 or 0.5 (instead of 10 in my screenshot)
hope this helps

1MMQGIS-plugin is availabel via official user contributed plugins pyqgis.org/repo/contributed, but you may also take a look at the pugins homepage michaelminn.com/linux/mmqgis. this is an extrem useful plugin! – Kurt Jul 26 '12 at 10:13
Another option is to use the built-in Vector Grid tool. (Toolbar menu: Vector → Research → Vector Grid):

Is this guaranteed to be in line with the real latitude and longitude lines? I didn't see how they choose where to start the lines. – mmmm Jul 22 '19 at 4:03

The grid starts at xmin,ymin and next coordinates are chosen by adding the specified horizinal/vertical spacing. The code that creates the grid is here github.com/qgis/QGIS/blob/master/python/plugins/processing/algs/… – spatialthoughts Jul 22 '19 at 4:31

Thanks! I ended up downloading a file with the lines I needed from Natural Earth. – mmmm Jul 22 '19 at 4:43
