Online maps, NSW.

Google maps are great for displaying roads and some paths but if you need topographic detail then head to the NSW Department of Lands. They have the Spatial Information Exchange (SIX) and the GeoSpatial Portal. The SIX interface takes longer to load the images, which look like scans of the actual topo maps. The GeoSpatial Portal still gives the contour lines and walking tracks but does not look the same as the real paper maps. Both have search features so you can go to an address or feature, say like a park or wharf, but neither will work on a mobile phone like Google maps. So if you need a pizza at the end of a bushwalk then stick to Google maps.
