Hello,<br>
<br>
The one major element missing from the otherwise great Quantum GIS, is that<br>
of easy setup map graticules. There is a basic way of doing simple ones in<br>
the print composer which is fine for geographic (WGS84) or UTM etc type<br>
projections, but will not work for conic or stereographic etc.<br>
<br>
Is there a plugin for doing this work (that is built-in to layout mode in<br>
ArcGIS) or is this an upgrade/update that will be available in a new<br>
release?<br>
<br>
Generating a vector grid does not work properly in 1.8.0, and certainly<br>
only partially completes a Polar Stereographic layout. There are clearly<br>
flaws that need to be addressed. If there is a reliable workaround for<br>
this, it would be good to know.<br>

A workaround is to make the graticule in WGS84 and reproject it to the desired end projection. I found that it doesn't curve well so I wrote this script to make graticules with a higher points density that projects well.<br>

I hope to work it into QGIS at a later point, but you can use it standalone with python to make what you need, import and reproject.<br>
<br>
Thanks,<br>

I am working on Antarctic data, so generated a vector grid for 0-360 in X (at 10 degrees) and latitude (-90 to -60) in 10 degrees. That all worked fine in WGS84. However, reprojecting to Antarctic Polarstreographic did not project correctly with less than half the meridians and no latitudes. <br>
