Saving map tiles/imagery

spartaracing

Is there a way to save all the downloaded map imagery onto my desktop so I can just drag and drop that imagery back onto my iPad when I do that same race the next year? So I won't have all that storage taken up on the iPad by leaving it there. Or is it better to redownload all imagery each time?

Yes by geeking out on a software program called MOBAC and by researching outside map types (most of the ones your going to want are not “authorized” for download use). This is a cost effective way to do it but requires a big computer and again some geek knowledge. This is a service we do for groups and teams under contract but is available to the general public.

Above this we can pull other sources of offline imagery down to 21 zoom and months/weeks old in mass but this bumps up to the $100k to million dollar range very quickly.

For $150 a year the in app consumer grade maps and current method of downloading you will find however to be the best economic way to do so

It is best to do a trip/event/race then wipe it out when complete and resave for the next one

MapBox is offering you this method of saving and storing map imagery for such a low cost by locking it down per device to protect their data from free public distribution. Can’t share it outside that iPad

You mean resave files (waypoints and such)?

Damian_offthegrid

No resave background map imagery an delete after trip unless it’s a smaller area/place you frequent regularly like Moab

Ok, seems that the current method is best then being as I'm not geeky. Thanks!

You can backup Collections (gps) files as much as you want to File app, Dropbox or ur computer

copy that, thanks. Yes I do that now and keeps my lead nav clean for when others are using it in the chase truck. They start playing with other files then they somehow manage to screw it up!

Ok so if I save my created route to file, I can then save it, like on an external hard drive to free up space on my I-pad but have it for future use?

You can do anything you want with Collection Folders/files. They are just GPS files in the standard GPX format. You can share them out anywhere and put then in any Garmin or Lawrence GPS (You may need to dumb them down using the Pro export to GPS feature) or you can convert them for KML for Google Earth. You can share them out to the Files storage app or DropBox.

Again they are just small GPS files and should be backed up outside the LEADNAV app and device if you really care about them.

Do not confuse these however with prepped and stored background map imagery. These are different and are saved and allowed to be "borrowed" for your trip per device that downloaded them. Then deleted. They are not yours to keep...they are yours to save out and borrow for each trip through these low cost In App subscriptions.

If you wanted to "own" these background maps we can do that as well but this will be a big contract so you would need to break out the checkbook! As these companies would want closer to the million dollar range to own outright.

So I understand imagery is just rented and all, what I'm trying to figure out is how I actually save the imagery for a trip so that I have the mapping up. This is my first attempt with the software on my iPad and I'm trying to save the imagery for Sand Mountain area and last time out I didn't pay attention and it was just tracking on the iPad no imagery.

Hey Damian, hope all is well.

Question: If I save a map tile at 16 zoom and then go back and drill down on that 16 zoom tile and save areas within it at 18 zoom, will those 18 zoom tiles download faster since they are overlaying on the 16 zoom? Or is it better to just start at the 18 zoom?

I ask because a lot of times I just need 16 zoom for scouting an area but when I find a good area I want to go back and save imagery in more detail.

Thanks

Damian_offthegrid

Will zoom faster and know what you already have.

However be aware...tiles are meant to be saved and “borrowed” for that trip, deleted when done.

This is currently being emphasized now heavily as we negotiate with our current map providers.

We seem to have been breaking their 30 day rule for your offline imagery/maps.

Among their limits of offline maps...

So expect big changes coming very soon. In fact before June 1 which is the deadline we received.

We maybe switching map providers/maps all together as we work through that the next few weeks

Noted, thank you.

I'm talking short periods of use where I download 16 zoom then a day or two later come back and do 18 zoom for more detailed scouting.

So to answer my question, strictly talking about when I am at home and downloading map imagery from wifi, will it download 18 zoom faster with the 16 overlay already there? I'm good with a yes or no, thanks.

Damian_offthegrid

Yes what we typically do is save our surrounding overview tiles in 15 zoom and the areas we will be operating in in higher zoom under it.

Sometimes the tiles may get "stepped on" if this gets a little crazy.... but this typically happens with people trying to use Advanced subscription to save way too many micro tiles. This can cause loading confusion...

But running fewer larger Pro pack tiles you can absolutely do this.

Copy that, thanks
