Downloading Maps

    I'm going to head off to Arizona for two weeks in less than a week.  I will have 1 1/2 weeks spare to bump around the hinterlands as I feel like on the fly.  I managed to download all US Forest service maps of AZ and the western half of NM, and now I'm trying to download the OpenStreemap data of the same area.

    While I really love most things about Back Country Navigator Pro, the download process seems neelessly tedious and error prone.  Unless I'm missing something, you can only mark areas for download at zoom level 10, which is very small for size of AZ.  Even so, when I laboriously scroll and define all the rectangles, it doesn't download everything, but doesn't tell me anything went wrong or try to fix it.  There are various random gaps at various zoom levels.  Since it's effectively impossible to check all data at all zoom levels is really in the cache, I can't trust it.  I don't want to be hiking around and find out the area I happened to be in is missing.

    Yes, I know I'm asking for lots of data.  However, if that's how I want to use the memory on my device, my internet bandwidth, and am willing to wait a few hours, that should be my business.  I see above that you do "not encourage" downloading large areas, but why do you care?  I don't know where I'll be in AZ and western NM, and want all of that data on my device.

    I found that downloading one screen full only at a time seems to work better, but it's a very slow and tedious process because every 30-60 minutes I have to interact with the device to acknoledge something or select more to download.  I want to plunk one large rectangle over AZ and western NM, then let it crank for a whole day if that's what it takes, as long as in the end I can trust all the data is really there.

    Another tweak that would make this process easier is not to have to wait for it to calculate the download size, then have to acknowledge it again.  I want the button that say "Yes I know it's a lot of memory.  I don't care.  Just do it.".  If I run out of memory, it can stop and throw up a error window or something.

    Sometimes it's been taking much longer than usual downloading screen-size areas.  Late Saturday it stopped working, didn't work Sunday at all, and now seems to be downloading but very slowly.  It's been stuck at 6% downloaded for the last 10 minutes.  At this rate, and considering I have to work a day job, I'm not sure I can get everything downloaded by the time I leave and won't have internet access anymore.

    Am I missing something?  Is there a better way?  If not, any comments on why it needs to be this way or, hopefully, that this will be addressed in the future?

    In case it matters, I'm running Back Country Navigator Pro on a Nexxus 7 tablet running the latest version of Android.

    Hi Pete,

     

    I hope you find them - did you update your OS by any chance? new external SD Card?

     

    Hi Ollin, 

     

    We did not receive it. Can you please try again? I will need that to escalate this to our dev team - 

    Your Nexus Tablet is NOT on a custom ROM, right?

    since after the pop-up about choosing your email application, it's an Android call function already to open up another app (for emailing the log) and not within the app's scope I believe. 

     

    thanks,

    Dan

    Hi Pete,

    Yes. The application automatically sorts out any tiles you've downloaded previously and does not download it again.

     

    Thanks,

    Hi Ollin,

     

    Apologies for being late in responding. We manage the helpdesk query faster than the forum here.

    What App version do you and and what android version does your tab have?

     

    Can you please send a log? this goes directly to our helpdesk: http://support.crittermap.com/entries/20061131-how-to-send-a-log-to-support

     

    Thanks,

    Hi Olin,

    I'm not sure why but can you confirm before downloading, the max zoom level you can choose is level 10? I tried it and I can go to level 15-16 and choose the "MAX ZOOM LEVEL" as well after you hit the "download" tiles icon.

     

    Another tweak that would make this process easier is not to have to wait for it to calculate the download size, then have to acknowledge it again.  I want the button that say "Yes I know it's a lot of memory.  I don't care.  Just do it.".  If I run out of memory, it can stop and throw up a error window or something.

    > There are actually limitations with how much you can download at a time within android. for now, it's maxed at 4Gb and there is no work around for it. 

    The maps are handled by various servers and the download rate maybe affected by the number of people downloading/accessing that particular map source. Some of them are public. 

    Our devs are working continuously to make the downloading process as seamless as possible. Please bear with us as we have a particularly small dev team trying to accommodate everybody's requests.

     

    Thank you for your consideration.

     

    sincerely,

    Hi Pete,

     

    Have you tried checking your bcnav folders if your downloaded package folders are still there?

    I'm also baffled as to what happened to your files.

    Thanks,

    I don't see mention of what is done about the overlapping rectangles.  Are these automatically corrected so they are downloaded just once or are they downloaded twice?  I may have read something about this before but I don't remember and I'm studying these guides to try to get a better handle on the details.

  • Dan

    Hi Mark,

    You can try zooming out and download larger tile segments, then just be sure to download to the max zoom level so that you get most of the tiles - please be advised that we do not encourage large downloads (e.g. whole states) in one go since, there are times the map server encounters hiccups, which would lead to your download looping - we cannot control nor predict this.

    Also, you can try downloading them using Map Packages, makes organizing much easier: http://support.crittermap.com/entries/22268768-using-map-packages

    The maps on the map layer section are free mostly, other than the hybrids with AccuTerra which requires a purchase.

    When you go to Menu > Settings > Purchase add-ons - each map should have a link to its website or to its sample.

     

    Thanks,

    Hi Ollin,

     

    It could be the cache - have you tried clearing the app's cache and Android's Cache (Menu > Android Settings > Storage > Cache storage)?

     

    please advise if it does help and sorry for this frustration.

     

    Thanks,

    Dan

    Just a comment while on a trip.  I'm sticking to the areas of AZ that I was able to successfully download maps of, and it's working great.  It's really awesome to have all the National Forest maps (the contiguous NF from west of Flagstaff into western NM is larger than Switzerland) handy and to be able to see where I am along the trail at any time.  I was hiking a loop in the Coconino NF, and was able to see whether it was shorter to return or continue when a thunderstorm rolled in.  That's harder to do with paper maps as there aren't always a lot of identifiable nav points like intersections for you to know where you are along a trail segment.

    Again, I really love BCNAV, but downloading large areas needs to be fixed.  I'll try to send you better information on that when I get back.

    Hi James,

     

    It should be on the notification panel(top). 

    What version of Android are you using? you might want to see this: http://support.crittermap.com/entries/27671140-Samsung-Devices-External-Storage-locked-after-4-4-updates-

    Hey Mark.

    Look at your Map Layers Menu and look at the link that says "Whats this" next to prebuilt map.

    You'll find some maps that are much easier to use covering large areas.

    Hi, Dan.  I don't have the tablet where I am now.  I'll try this evening.

    I can see the point of clearing the Android cache (I didn't know it had one), but wouldn't clearing the app cache delete all the tiles I did manage to download?  I don't have time between now and when I leave to recover from loosing everything I have so far.  It was pretty tedious getting all the National Forest data for AZ and western NM.  I'd rather not do that again, and I probably don't have time for that before I leave anyway.  I'd rather do nothing than risk loosing data I already have (around 15 Gb).  Unless you tell me that the "tile cache" is different from the "app cache", I don't want to take a chance on messing with it.  Please let me know.

  • Olin Lathrop

    I'm back now, and having all kinds of issues with BCNav.  I still can't download any new data, and now exporting GPX files of tracks I took for mapping doesn't work either.  I have setup email on the tablet and tried to send another log while it was in the middle of trying to download data.  This time I didn't get any popup about choosing a email application, so maybe it got sent.

    I'm pretty much dead in the water with BCNav.  Let me know what I can do to help you diagnose this.  I'll send you the tablet if you think that would be useful.

    I am a newbie and downloading a map selection to an LG G tablet 8.3 (running Android) and do not see any download status indication.  Where can I check to see if the map is fully downloaded?  

  • kurt finvik

    I got a samsung s4+. I have downloaded maps on my device. Almost full memory. Can i move the maps over to a SD card?   Kurt Finvik

  • Dan

    Hi Ollin,

    but wouldn't clearing the app cache delete all the tiles I did manage to download?  > this is the cache for the map tiles saved on your device's temp folder for Maps that are "streamed". 

    If you downloaded the tiles - it should still be saved there (either on the main tile cache or a specific map folder/package)

     

    Also, it would be sound advice if you back-up your downloaded data to your PC - this will save you a lot of headache in the future.

     

    Thanks,

    I don't see the progress as % complete. All I see is a bar with bands moving along it. It's been downloading for 45 minutes now.

  • Deserthiker

    When I try to download maps and I get to the "Space available on disk" section I click on "proceed" and I get this message "Unfortunately, BackCountry PRO has stopped.  No other explanation. Where do I look next?

  • Olin Lathrop

    I got home and tried it.  From the Android "internal storage" screen, I deleted all cached data.  Just in case, I then powered off the device and had it completely reboot.

    I tried downloading a small part of a screen at zoom 10, about 17,000 tiles (a full screen is around 160,000 tiles).  It went OK for a while, then hung when it got to 50%.  After that, the app won't even load tiles anymore interactively as I'm panning around.  It seems getting any kind of data over the network is now completely hosed.  I checked, and "Online&Cached Tiles" is checked.  Other network access works fine, so it doesn't seem to be the WiFi or network connection.

    Now what do I do?

  • Dan

    Hi Rick,

     

    What version of Android do you have? Where do you currently set your default storage to?

  • Dan

    Hi Deserthiker -

     

    Sorry about that, some posts does not go through our automated spam filter and we clean them up once every week manually. There's literally hundreds of spam comments that we need to filter through.

    Please comment with your answers based on Pete's question and we can work from there.

    Hi Pete, 

    Thanks for that! you did ask the right questions :)

     

     

    Sincerely, 

     

    Dan

    Hi Ollin,

     

    Can you please send a log while the download hangs up? (http://support.crittermap.com/entries/20061131-how-to-send-a-log-to-support)

    After you send that log, I will escalate this to our devs. 

     

    Thank you,

    Is there a way to download a map without doing the rectangle-select of an area? I want to hike the PCT through all of Washington state, but the select process is very tedious because I can't do it at a large zoomed out view so it looks like I have to do a zillion select/scroll steps. Maybe I'm an idiot but that's all I know.

  • Pete Larson

    FWIW, any area worth downloading is worth saving to its own created and named map folder, IMO.  Although I'm currently tearing my hair because my map folders disappeared a few days ago.  If I don't solve this it will become another topic.

  • Sebastian Dollinger
    How can I change the location the maps are saved to? I'd like to use my external sd instead of the internal one.
  • Dan

    Hi Joe,

     

    Unfortunately, No.

    We do not encourage download very large parts actually (android has a file limit of 4Gb downloads). 

    Did you want to download the entire state?

     

    Thanks,

    Hi Dan,

     

    The fact is, I have never upgraded the OS from 4.3 so my GS3 perpetually tells me it has a system update downloaded for me to install.  I lost these folders once before a couple months ago and I'm trying to remember what on earth I did to get them to reappear.  My Download History shows all the packages I've got but I'm at a loss.  This disappearance just happened after I went kayaking last Sunday and tracked the route.  I reported the stats to my paddling friends and later when I went to look at it again, everything was vanished, track, stats, map, folder, etc. plus my other dozen folders..  My folders and maps represented a lot of work and I fear I may just blow away all the cryptic numbered data and start over.  Not a happy thing.

    Hi Sebastian,

     

    What Android OS version do you have?

    You can go to Menu > Settings > Storage Options and choose a new directory/path.

     

    If you are on Android KitKat 4.4.x - please see this: http://support.crittermap.com/entries/27671140-Samsung-Devices-External-Storage-locked-after-4-4-updates-

     

    Thank you,
