Re: Download Google Maps Offline Card
Mina Spartin
As @MervynLotter mentions, you can still sideload TPKs, VTPKs, etc. onto the SD card to minimize the impact on the internal device storage as outlined in this doc topic. You will also need to define this as part of the map's offline properties if this is the default basemap that should be used when downloading the map.
One benefit of ArcGIS Field Maps is that you won't have to have separate TPKs in each app directory as you did for Collector, Explorer, etc.
I can only reply to the question about basemaps as I have done in Field Maps. The latest releases of Android make it more difficult for Esri to utilise folders outside of those created when the app is installed so you now need to place your basemaps in "Galaxy A70\Card\Android\data\com.esri.fieldmaps\files\basemaps" (in may case but it should not be different to yours).
I don't think I made myself clear, sorry about that. You can still add your TPK files to your SD card (and I have a 1.3 GB tpk available to me as a basemap on my SD card), you just need to access the correct folder with a little more effort. So browse to the following folder on your SD card, and then copy your basemap into this folder. "SD Card\Android\data\com.esri.fieldmaps\files\basemaps".
Previously we could move the TPKs from the SD card to the data folder for use in the application. But with Android change, we no longer can access the data folder directly on the device to move it. We'd have to connect to the computer to be able to move the TPKs. Due to this restriction, field workers have to prepare ahead of time, which they might not have the ability to do before having to go into the field.
It would be nice to be able to have a secondary location to check for basemaps so that we could designate the SD card as another directory instead of having to move the basemaps to the specific folder in the data directory.
I can't get Field Maps to find the TPK basemaps on my microSD card. I filed them in Android\data\com.esri.fieldmaps\files\basemaps. But Field Maps doesn't see them there. When I file them in my phone's internal memory in the same folder they do work.
Setting up my Google maps, I attempted to download an offline map to my SD card which I had formatted in my new phone and repeatedly got the "Couldn't download" message for every attempt to download to SD card. Swapped SD card - same result. Download to device works OK.
Now luckily (for the test) my wife had postponed her UI 5.1 update on her own A33 5G and she was still on UI 5.0. So first I attempted to download an offline map on her phone with UI 5.0 and it was successful. Swapped her SD for my SD card on her phone and a download was successful again with my SD card with UI 5.0.
With offline maps in iOS 17 and later, you can use Maps for information and navigation even when you don't have a Wi-Fi or cellular connection. Offline maps include details like hours and ratings on places, turn-by-turn directions for driving, walking, cycling, or riding transit, and estimated arrival times.
Offline maps do not sync across your devices. Offline maps are only available in select areas. An offline map for a specific region is not intended for use in all regions. Features vary by country and region.
As Google continues to make it harder for applications to share data, you may have to move your offline maps and GPX save location to a MyTrails-specific folder rather than the traditional /sdcard/MyTrails.
A, B and C do not need to all be offline maps. in fact, it may be useful to select an online map as the last map in the chain, so that there is always something to display. This is what MyTrails does when you create an offline map and check the Let MyTrails download missing tiles option.
On recent versions of Android, even the internal storage may no longer be accessible to MyTrails. One location that should always be available is /sdcard/Android/data/com.frogsparks.mytrails. This is the offline location you should use if all else fails. Warning: that location is deleted by Android when you uninstall MyTrails!
Alternately, you can use the standard Android file picker with MyTrails, which makes it possible to load and save GPX files from anywhere. Enable it by turning off Use internal file picker in MyTrails > Preferences > Other.
In order to avoid having the Android Media Manager index all the files MyTrails uses for offline maps (thus wasting space and battery on every startup), MyTrails adds a .noscanandnomtp file to offline maps.
Even for premium maps (except IGN), such an abuse-prevention is used, and MyTrails will be able to download only 10,000 tiles per 24h period. The limit will be reset 24h after the first tile was downloaded, not 24h after the limit was reached.
Note that at latitude 45 for zoom level 15 (the zoom level used for 1:25,000), each tile covers about .8km, so 10,000 tiles represents about 8000km, so the most popular offline subscriptions can be entirely downloaded without hitting this limit.
How did you use your offline maps? Note, if you touch the Offline maps button, you will be given the option of updating, deleting or creating an offline map. To actually use the maps, just use google maps as you normally would. The program will automatically load the appropriate offline map if a data connection is not available.
I know I can use Google Maps without any data (as I have no data plan). Would you be willing to try [Maps.me]( ?). This is my backup in case I forgot to load the appropriate map. Maps are meant for offline use, they are in vector format so they do not take up as much space. I find they are not as accurate as google maps, but I they are a great backup.
I agree, the gps should work without a SIM card.Apple maps worked, that is I could follow our progress as we walked, but I could not get directions without WiFi. Google maps gave perfect bus and subway directions over WiFi
. I took screenshots of the directions before leaving the WiFi area.
When you are using Google maps offline - is your location being actively tracked ? When I use Google maps, I can always see my progress. However, if I try to get directions to a unique place, it is hit or miss. I usually need an active Internet connection to plot a new course from a unique location.
My workaround (which does not alway work) is to do my plotting before I leave home(I save the locations in My Places). I am not sure why this is the case as Google Maps is perfectly capable(most of the time, but not always) of rerouting when I am off course.
The video below shows how to change the directory for offline map data to an SD card on Android 5.0 as on higher versions this process is simpler. Unfortunately, it is not possible to change the directory for offline map data to an SD card on devices with Android 4.4.4 and lower. On Android 6.0 and higher when you navigate to the SD card you just need to grant permission to write to SD card through showed dialog. On Android 5.0 in showed dialog you need to navigate to the actual SD card into which you want to store offline map data and then tap on Select all button. You can also follow step-by-step tutorial for Android 5.0.
Yes, GPS works because it is completely independent of any WiFi or Cellular data connection. A GPS is just a radio that receives location data from satellites, so its radio is separate from any WiFi, Cellular, or Bluetooth radio.
The navigation system consists of three main components: GPS receivers, maps and navigation platforms. Your phone features an integrated GPS receiver that can determine your location without cellular data.
Maps can be stored on your phone and need no connectivity, as they are not changing much. This is done if you download maps, also known as offline maps. Offline means no Wi-Fi or Cellular data connection needed to use the map.
This GPS data combined with Google Maps can show you the exact location coordinates on a phone and provide navigation so you know where you are going. Without offline maps, your device may need a data connection to a local cell tower network, which can cause you to be unable to locate your location.
In other words, the GPS may not automatically turn off in the latest iPhone or Android operating system. This is an important benefit, especially to travelers whose phones are not accessible from their home area.
This is why airplane mode saves your cellphone battery during a flight. If you leave your phone in regular mode, it will work very hard during your entire flight trying to find a cell tower, and there are none available at 35,000 feet.
Yes. On Android and iPhone devices, the Google Maps app can locate and follow you wherever you are without the internet or without data. The GPS on your smartphone is able to do both things at the same time.
No, the GPS receiver itself has no need for the Internet, but if you are using an app, like maps or navigation, or require real-time location tracking, then that app will need the Internet in order to exchange information and work properly.
When it comes to sense of direction I rank really low. I heavily use Google Maps to find my way around, at least for the last two years now. Before going to England I went on a sponsored trip with Google Maps in India. I learned many few useful tips and tricks there. I was looking forward to use them in London, particularly London Underground! This was my 6th visit to UK as I used to go there for work. My last trip however was in 2011.
