    Does anyone know of good electronic topo maps of Australia please?
    I'm running the Natmaps Raster 2005 maps which are mostly really good, but occasionally send me down a farmer's private track or to locked gates. Interesting way of meeting new people...:rofl
    Will the latest Raster maps be better?
    I use the maps in Oziexplorer, on the PC and the GPS.

    I'm unsure what you mean by raster maps, but free shonkymaps works with garmin's free basecamp software, and is a gps-enabled dataset that uses the Natmap 1:250000 maps as a base.
    The GPS maps Garmin Topo and OzTopo both do the full country, but cost money.

    It really doesn't matter whose maps you use, they will all send you up farmer Brown's driveway at some point.

    It's never happened to me with opencyclemap.org (which I also use on my smartphone) since the data is created by real people who've ridden down the goat track on their trail bike instead of pulled from satellite photos or 80 year old government map data.

    Depending where you're riding the map data varies from incomplete to awesome. But it never suffers from telling you there's a road where none exists.

    Only problem is it doesn't show roads and tracks when you damn well they are there. I guess this system is relying on people actually traveling a route then up loading.

    I will stick to my Memory-Maps and Oztopo for planning and up loading to my GPS.

    Format .. simply put:

    • Raster ~ like a photo .. jpeg/tiff/bmp etc. Describes each pixel across the screen.
    • Vector .. describes a line as a start and end points.

    ------------------------
    The shonky logic maps are vector ... but taken from the raster topo maps of some decades ago.
    The government produced topo maps are available (for a price?) from geoscience Australia .. http://www.ga.gov.au/search-data-and-publications?queries_keywords_query=index%20map&topic=navigator

    The 50k scale maps are dated 2004.

    --------------------------
    The opencyclemaps (intended for bicycle riders) are based on 'Open Street Maps' (OSM) .. that data is contributed by users based on

    • their own surveys - gps tracks, photos private knowledge
    • satellite views (Bing, AGRI, Mapbox to name some of the current providers)

    So the data may be based on satellite data .. and that may not see a locked gate. But you can add your data to the map .. or report things to OSM and it may get fixed when some volunteer takes it onboard.

    ================ edit .. added below
    Raster maps won't (yet) auto route. Vector ones can auto route (if they are configured for it).

    I should have been more specific. I have been using Natmap Raster Premium 2005, 250k scale. http://www.gpsoz.com.au/natmap_2005.htm

    It has been good mostly. I had to convert each utm zone map into the correct format for the gps, which runs windows ce. The conversion software is img2ozf or something like that. This can take a while.
