Thanks for the question. Currently maps cannot be uploaded to our system but this is in the work flow for future development. We will also be adding the Ollie O'Brien open source overlays at sometime. The look and feel of these maps are more familiar to orienteers.
Hi - No update on this one at the moment. It is in the workflow but the the new version, yet to be launched has taken a lot longer than expected. I'll post something when we get going with this part of the APP.
Just as a thought we have a few users who use paper maps with the Sporteering APP and don't use the internal mapping at all. Give me a shout if you would like more details.
