Hi everyone in this thread, I have tested the following apps over the last week:
Google maps off line mode.
Handy GPS (Free)
MapDroyd.
All are available on the Play Store in your phone.
When testing I put my phone into Airline mode so the transmitter was disabled and I then knew it was in "off line mode". I travelled within a 60km radius of Cairns, I use optus as my carrier and there are some blackspots in my region so data / network location assistance was not possible in a few of the spots. Also due to dense canopy, I could not always get a signal from the onboard GPS.
MapDroyd, Forget it, could not get the thing to work properly and when it did, the maps are incomplete, seem to be based on goolge maps from a few years ago.
Handy GPS is great for getting your exact coordinates in both lat and long and WGS GDA coordinates, did not try the coordinates on a topo or geo map cause I did not have one. It uses updated google maps and works ok in off line mode. Another feature of this app is the waypoints, you can create a waypoint for the spot you are at and label it. It also offers the option to export your way points in .kml format for use in other gps software.
Google maps worked ok, gave me the direction i was heading but I can not figure out how to get coordinates out of it,
I am running with a combination of google maps with off line data stored and the Handy GPS for its waypoints and coordinates. This seems to give me what I need as far as geolocation goes.
Another app worth mentioning is GPS Test. This is a good tool to check the number of satellites you can see from any given location, I was using it as comparison for the other apps.
I will update in a few weeks when after going to more remote localities.
Good hunting everyone
