Help finding OziExplorer topo maps

Cheers Richard, just adding them to my wish list for when I get home. Going to be doing more South West WA trips after getting back home from Broome.

Why? Isn't every mapset shown there available in Ozf2, Ozf3 or ECW format? :-)

Yes you are correct - but Richard did say "may also need" so we can let him off on a technicality. I always prefer to change even ecw to ozf format anyway, but there is no real reason as I am lead to believe ECW files work fine. Ozf may just load a tad faster (especially the bigger size files).

I will keep an eye out

Hello Doug - Firstly T4A uses same data as the 250K maps so using the raster set with Oziexplorer will have same detail as the t4A you use. True, the t4a are in vector format and you can zoom in and screen stays "pretty" (apart from increased jagged nature of linear features such as rivers and roads due to scale of data capture) - but you are not really gaining anything over using the raster 250K set, and neither will have the detail that is found on larger scale maps (eg 50K or 25K).

There is no point in zooming in past a certain point on raster images anyway - no extra detail will be revealed. You dont buy a paper map and then hold it against your face in the vain hope of seeing something extra which is what you are doing if you zoom in too close with a raster image...so why do it? The advantage of having raster images for use with OziExplorer is well documented and they have uses that paper maps dont (and visa versa).

While discussiing vector mapping is off topic on this thread just like to state that if you did want decent vector mapping for a GPS (and werent afraid to actually pay some money), Magellan mapping is probably better option than Garmin anyway - DiscoverAus has street level data (unlike t4A and shonky) in addition to (at least the WA section) having roads and tracks as found on the 25K series of raster maps.

PS - the digital versions of the various map series available on DVD are far cheaper than purchasing indvidual map sheets if you plan on getting a few. For example the Kimberley 50K DVD contains 483 maps and costs about $120. For $120 you could only buy ~12 paper maps:( With the digital version you can also just print out areas you want as well - very handy.
