In this tutorial I will show you how to use the Print Composer in QGIS it to export high resolution height maps. This tutorial expands on Getting height maps from QGIS.

It is worth doing this one first if you're unfamiliar QGIS. To follow along, download from Koordinates a heightmap of Wellington (or if that is too big a download, use one of Christchurch).
