I mean does it allow me to choose any map, just like if I was using paper maps?
Thanks

Yes - and you can also use an external gps unit to link to the iPad via bluetooth and use the iPad for navigation. You just need to make sure that the app recognises the external gps. I have a Bad Elf GPS Pro that is designed specifically for the iPad and it works well with the Hema app.

They are different tools for different jobs. I have both and use both. If you want directions and city navigation then HEMA is not for you, you need a tomtom/Navman etc. but they are useless anywhere remote or off the beaten track, they just get lost and stay lost.

I also find the HEMA much better for touring as you get to see the picture of where Yu are heading, what the next town is how far away the next town or highway turnoff is etc which you don't get with the normal satnavs

OK mine is now working well except... the toppo map is years old and a lot of roads are missing. Can this map be updated? Jim

If you mean the 1:250K mapping, it's based on the NatMap imagery which was released in 2008. There hasn't been any update from NatMap so this is the latest version at that particular scale.

There is additional mapping that is available from the memory-map store: Aus Maps : Topo maps | 4WD maps | Australia maps | PC : iPad : Android | Memory-Map Aus/NZ

To go beyond that you need to purchase the 3rd party map import option ( Memory-Map software features | Pro | AIS | Remote Tracking ) for the PC desktop application, which allows you import and calibrate additional mapping for use in Memory-map/Hema.

Problem with all these mapping "solutions" for iOS (memory-map/hema and mud map in particular) is they lock you into a mapping ecosystem that is designed to benefit the map makers and app vendors rather that providing a versatile navigation platform for the end user.

There are a lot of roads in my area (and I dont mean street by street but main through roads ) that have been there for years but are not shown on this map. Jim

Hi Jim,

The AusTopo 250K maps included with Hema map package are 1:250,000 scale mapping. If you relate this to a paper map it would mean 1mm on paper equals 250,000mm (or 250m) on the ground. At this scale you don't get much detail in cities or towns. So it's not a question of updating the 250K maps to show more information, rather it's a matter selecting a more appropriate map to use for the task at hand.

For street directory style mapping you can buy the UBD street maps on a state by state basis for $18USD. I used the NT package around Darwin last year and found them very well suited for getting around town. Obviously it's not turn by turn but the mapping is very clear and usable for this kind of navigation.

You can download the zipped map packages from here:

Packaged Map Download : Hema maps, Marine Charts, Topo maps for PC, iPad or iPhone | Memory-Map Aus/NZ

The unzipped maps can be transferred to your iPad using iTunes. There is a 10 day demo period on all these maps.

cheers

I'm posting up some screen shots of mapping to try to explain the difference in scales.

This first image is the Geoscience Australia 250K mapping that is the basis for a lot of the commercial 250K mapping.
This is available in a format that can be loaded into mapping software and modified extensively.
As supplied this mapping can be pretty hard to read.



The next image is roughly the same area but taken from the Hema AusTopo 250K mapping.
There has been a lot of work done to improve the legibility for touring navigation, but you still have essentially the same level of detail.



I'm cheating a bit here, as this next two images are from mapping that is only available in OziExplorer format.
This is taken from the Spatial Vision VicMap DVD and shows the area around Essendon Airport at 1:100K scale.



The Spatial Vision mapping covers some built up areas at 1:50K



And finally, the Memory-map supplied VicTopo 1:25K mapping of a section of Essendon Airport.
There is much more detail BUT I find this mapping next to useless when driving.
If you zoom in far enough to see the track detail, you only have 300-400m of track on screen so it's hard to see the overall context.



cheers
Paul
