The routes and landmarks saved in the GPS are displayed much more legibly on the computer monitor than on the tiny screen of a handheld position finder. Any names or map script downloaded from the GPS are displayed in little boxes. Each reading taken by the positioning device is time-stamped, allowing you to replay the route you took.
The software comes with no useful maps, so it's up to you to supply this information. But surely you can buy Australian maps in digital form? I don't dare repeat what our national mapping agency at www.auslig.gov.au is asking for this virtual property - it's a national disgrace, go see it for yourself. Fortunately, scanning in paper maps can produce satisfactory results.
So, you have a map displayed. You have the landmarks you have obtained from free sources or your GPS supplier, and you have data you created with your GPS, all displayed at once. You can now plan a route, or print out the whole lot for future journeys in the same area.
You can - but surely it could be easier than this. There are arbitrary limits to how far you can zoom in on the map, the icons are tiny, the software does not support vector maps (think about that one). There are various crashes and no "undo" item in any menu. That said, the developer is still very actively improving this application, and the CE version for palmtops is probably where most consumer interest lies. OziExplorer is shareware, with a free trial period of 30 days.
