A first use I see for it is to have a better idea of scale and easily see the extents and distances.
When I first started using QGis I thought that that an easy way ti have a grid on the canvas was missing. I started this thread a few months ago and decided to implement it as a decoration. I also refactored the decorations with a base class. http://osgeo-org.1560.n6.nabble.com/show-grid-on-map-canvas-similiar-to-grid-used-in-composer-strategy-td4964055.html Before implementing this feature the only way to draw a grid was to use the ftools "vector grid" tool which is cool but a little clumsy (have to save a shape file) and has some performance issues with high-resolution grids (esp. when saving as polygons). My initial motivation was to be able to make a grid from a raster (which was created by rasterization of a polygon vector layer), to see if things lined up correctly. John Donovan is working on a more flexible plugin to draw complex grids - see the above thread also Etienne On Thu, Jul 5, 2012 at 7:35 AM, Nathan Woodrow <[email protected]> wrote: > Just been playing with the new grid decoration.
