NATMAP RASTER MAPSHEETS

$119 for the deluxe

Gidday, what is the benifit over the older versions???

Time to admit my ignorance of electronic mapping aids.
How useful are these particular maps on my lappy ? How do they compare to the Desert Tracks ones for those areas ?
Yes I'm suffering from information overload (lots going in but nothings staying there :). Surely I can't be the only one.
5 mts demo would tell me all I need to know, but since I'm here and they're there I have to ask silly questions :))

TIA

Hi Peter

I think from what they say the new one is better in the quality of the maps i dont have the old set only bacause i was not ready to get them as yet but now i have the laptop all set up and will be doing some long trips and it will be handy and not have to sort out all the maps i will need to take it will all be there ..I think its all down to distance per pixel
standard is 50 mtrs and deluxe is 20 mtrs per pixel

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.
