Hello

Sorry cant help with all your query but can say that the maps are not "routable". While the online version is in vector format, the maps are supplied in raster format (i.e. an "image" like a digital picture) and don't have any associated information that would allow for routes to be calculated automatically. Also zooming in on raster maps will not provide any more details - its all there to see in the first instance, though getting closer allows you to distinguish between features more clearly (like holding a magnifying glass to a paper map). How close you can zoom in is dependent on the viewing program you are using and the resolution of the map image. In OziExplorer you are limited to a 200% zoom with the original 250K topo..not sure of the limit for EOtopo ...but anything past 200% is likely to result in a blurry (pixelated) mess.

Keep in mind EOTopo is based on 250K map data with more detailed additions made in select areas from GPS data taken from ExplorOz user treks notes....so in some areas there will be more detail than available on the standard 250K topo and in other areas there will be no difference i.e. many roads and tracks that you know of could be missing. If you are limiting your activities to a certain area there maybe other map sets available with more detail, but maybe not - depends what area.

Nick,

The online version is derived from the same data sources as the 200K product - the actual 100% zoom equates to approx the 5km zoom level however it shows the 1km zoom detail - this is due to higher resolution output of the information. So in reality what you see on the 1km level is the basically what you get on 200K.

Is there something wrong or missing? We are about to start the next rounds of updates for the 2014.4 release so anything that can be attended to now is the time to let us know.
