One of the tasks for the weekend is to write a summary of my experiences with GPS as a mapping tool. Sort of useful will be my conclusion. But I'm far more interested in LIDAR and digital mapping. Here is one way of mapping the Hattah area. You could consider this as a map based on 20 cm contour intervals. The colour gradient doesn't really show it. Someone sent this map to Obewan who passed it on to me.
Is the area good for orienteering. Well, parts might be. There isn't much runnable sand dune country in Victoria. This is runnable. But its a long way from Melbourne. Obewan and I are more interested in organising a rogaine here. We had a great time at the Wilderness navigation challenge using a map with aerial vegetation detail and 10 metre contours. the contours were dodgy. The vegetation image was very useful in part of the map. This is what the red gum country looks like.
If we could get access to the LIDAR data and recent aerial digital photography, a very good rogaining map would be possible, with little time in the field. BTW, thats a 1km grid as far as I can work out.
