I think the additional functionality provided by EO Traveller and I presume other packages such as Hema and OziExplorer (which I haven't used), make them better apps for touring.
One of the family used the app while bushwalking in Namadgi NP and found the cached sat image invaluable when taking a route marked on the map that became poorly defined on the ground. I think these various packages are complimentary, I wanted the offline sat images as 'insurance' so if I became confused about a route and couldn't see a marked track on the ground due to changed conditions a geolocated position on an image would reassurance. Now if you could only overlay the sat image with a map!! The YouTube clip is definitely worthwhile watching and mirrors my experience with the app. For a limited area, that you knew you wanted in advance it would be great, I'll definitely be trying again. It would be much easier if the area of interest was squarer and smaller so that you could get the entire area of interest in a single box and download. Even with a 50MBs download (~36 over wifi) it took several days of constant downloading and there were missing tiles and various glitches. A year ago when I tried to download a cache for Hay R Track it was tedious and not very successful for a long and narrow but large area. To use the Aust Topo ESRI aerial images offline, they need to be cached. As I understand, ESRI aerial are a mixture of satellite and air photo images so it might depend on where you are looking. The satellite images are good, the ESRI aerial images seem to be a slightly higher res (smaller pixel size) than the online EO Traveller images. Google Earth lets you fly anywhere on Earth to view satellite imagery, maps, terrain and 3D buildings, from galaxies in outer space to the canyons of the ocean. Wednesday, at 11:52I have the Australia Topo Maps app.
