I've taken the plunge and bought a PDA and blue tooth GPS, all very fancy, from local computer guru Blaze. I've got some maps but looking in Exploreoz
shop, the Natmap raster obviously covers all of Aust. The CD version and DVD versions are fairly similar in price, but do you need the extra detail (and therefore extra memory space ) of the DVD version or is the CD version adequate for moving map stuff when travelling. I am a learner so don't understand that clever computer geek words so plain english answers and opinions please.

He are the facts on the two NATMAP products from the Geoscience Australia Website.
"What are the differences between NATMAP Raster and NATMAP Raster Premium?
NATMAP Raster Premium has higher quality images than NATMAP Raster. Premium edition images have lower compression rates applied and in some cases smaller pixel size.
NATMAP Raster Premium is supplied on 2 DVD-ROMs whilst NATMAP Raster is supplied on 4 CD-ROMs.
NATMAP Raster has 514 individual maps based on MGA94 (UTM projection). In NATMAP Raster Premium, these maps have been mosaiced into separate UTM zone maps i.e. zone 55 contains all s*55** numbered maps as a single map image.
Map content and software operation is identical between versions i.e. NATMAP Raster and NATMAP Raster Premium operate in exactly the same way.
NATMAP Raster Premium Landsat satellite image has 25 metre pixel size, whereas the NATMAP Raster satellite image is coarser with 50 metre pixels.

All you need to load onto the PDA (or better still a memory card to save space) is the 8 Zone Maps (Zone49 -Zone56).
I assume you will be using OziExplorer on the PDA to reference the maps?
Ozi provides a free download program which converts the *.ecw map files into a format better used by OziExplorer CE. (The version of Ozi that runs on a PDA)
The program will save the map files, including the Map reference files, to a CF Card.
The easiest way to do this is to use a card reader so that the CF Card appears as an additional removable drive on the PC. Conversion of all eight files will take almost 24 hours, or you can select one at a time.
Any more help you need with information to help you choose the best approach, please don't hesitate to ask.
