Download Maps For Offline Use
Linn Lievsay
After you download an area, use the Google Maps app just like you normally would. If your internet connection is slow or absent, your offline maps will guide you to your destination as long as the entire route is within the offline map.
Offline maps that you downloaded on your phone or tablet must be updated before they expire. When your offline maps expire in 15 days or less, Google Maps tries to update the area automatically when you're connected to Wi-Fi.
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.
After that I thought, is something wrong in layer1 (related table). So I exported the feature layer as FGDB and reuploaded it to AGOL and created a TEST Map. Now this worked perfectly fine when I tried to download the offline area.
The next obvious step was to try and break the TEST layer. So created a new field with name of more than 31 characters. Then I tried downloading an offline area, the result was a fail with the same error.
Removed the troublesome field and I am able to download offline areas on my phone/iPAD.
A few other tests have confirmed this. It is the field length that causes the issue.
There is no limit (max 31 characters) in AGOL when you create a new field but when you try and download an offline area/replica then possibly that limit kicks in and the process fails.
Ill also add here that this problem will occur when your hosted feature service schema contains attribute field names that are reserved Sqlite words. For example, a hosted feature service can have a field named "group". If you try and download this feature service in an offline area you will get the above error as "group" is a reserved sqlite word. See _keywords.html for all words that you should never use in AGOL as field names.
I am just wondering if anyone else has been having this issue. I can set up an offline area in the Field Maps online web application, then when I try to download that offline area on Field Maps Mobile (tested on two android devices) I receive the "Offline Areas Failed to Download" Error and the log tells me that feature tiling is disabled. Now this is frustrating. However, when I create on offline area in the Field Maps Mobile App, the map is created an downloads just fine.
I ran into this issue and was able to "fix" it by turning sync off, then back on for ALL layers included in the web map, make sure any tile packages included in the map or basemaps have Offline Mode enabled:
It would be good if anyone from ESRI could confirm if there was some sort of limit to the number of features with attachments or best practise with attachments. In my case I want as a read only reference layer a point layer which may have several hundred points each with a single photo attached. Is that asking too much of field maps?
So I decided to downgrade the image size of my attachments because when you click on a dot to see its attachment (in field maps) it does not appear to be a zoomable image. So I decided to resize the images to 800x600 pixels which significantly reduces the file size. This allowed the download to complete without error and I get to keep the whole dataset, no need to break it up into several "Map Areas".
I currently have a support ticket open with ESRI about this and she casually mentioned that attachments have been an issue for folks lately, but it does not appear to be a main focus of our troubleshooting so far (I do have layers with attachments). I am currently tasked with republishing all of the map layers and recreating the maps- glad (?) to know others are having this issue too and it's not just me!
I have gone into the projects that I have completed and deselected the toggle switch for offline maps but this appears to have no effect and when I look to add another offline project my total is still as it was.
Hi Murray,
Yes, that is the way DD told me to remove the offline maps. Make sure you turn off Available off line option, then delete app and reinstall. I have a lot of offline maps cached and I need to delete them as I go along. Flight plans and data are not effected as its held on the DD server. Offline option is in your IOS device. Give your ios device time to sync before re installing. Hope this helps.
Sorry to hear about your maps not un-syncing from the offline status. Some devices have a hard time un-caching flight plans than other.@Kapchaking is correct, you will want to uninstall the app but make sure to allow enough tie for the flight plans to sync. I hope you find that helpful
This group is for use with ArcGIS Field Maps in which members need to edit the feature layers. We also need the ability to manage offline map areas. I am able to do this in other established groups with folks editing data and web maps shared to the group where I manage offline map areas.
How can I have a web map shared to a group where group members can update the items in the group and I can also manage the offline map areas for use in Field Maps? I have been doing this for other groups over the last year without this 'Shared Updates' label and offline map areas? Today is the first time I've received this new 'Feature disabled' notice. So I'm supposed to unshare and reshare each time I want to create a new offline map? What is going on?
I think my situation is a bit more complicated as I don't own the map and I am only able to edit the map because of the shared update group. And I wanted to create a new offline area because the existing offline area failed to download on devices (which seemed like another weird situation that many had...). Wonder if anyone knows how to solve the situation?
I've just come across this too. I was trying to enable colleagues to update webmaps I'd created by sharing them with a shared update group but then I lost the ability to manage the offline areas myself, even though I am the webmap owner. Did anyone find a fix for this, or is the only way to manage offline areas to log in as the map owner? This seems like a strange limitation.
No I'm afraid not. Wiping the group and making a new one with the 'All group members can contribute' option left everyone, including me, unable to create offline areas. The only solution we've found for other team members to create offline areas is to log in as the map owner which involves sharing passwords so not really a solution.
For example, c:geo is a open source project, which I found today by recommendation, and the map engine supports both raster and vector maps (and plenty of other features). I did test the engine, and it does run smoothly, even with a 4Gb .map Mapsforge vector map. Sharing offline map files, to save space, with other mapping applications can be done: -howto
I think this is a great idea. But until 1.0 the only thing I can sign up for is the current current maps. I used mapbox because it is super well documented and free for up to 15Kish map views per month.
Hi just for info re hiking with offline maps. I would use openandromaps.org to download maps and use them on cartograph. Usually I do this on my iphone but cartograph do have an Android equivalent although I have not tested it.
Openandromaps offer mapsforge maps which are great for hiking. You also get POIs.
Cartograph allows you to record your track.
I have no idea how you could code the Meshtastic app to allow you to have a selection of offline providers unfortunately. So I cannot help much!
Hey guys, have a look into API for Locus Maps. They were helpful when I tried to design a prototype of LORA based tracker integrated with their maps and API. They offer free version and of course the paid one (for approx. 10USD per phone installation). They have great offline maps and huge community.
If you want more, you can also set up your own rendering, and use it with Marble. But that would require a quite heavy computer, and it's not documented how to achieve it in Marble (because they are afraid people will use it to display proprietary maps).
If you have Marble installed you'll have an "/usr/share/kde4/apps/marble/data/maps/earth/openstreetmap" directory with an "openstreetmap.dgml" file in it. In there you can see how the tile servers are configured.
Knowing how to download offline Google Maps is an important skill to know, especially if you're heading off into the great unknown. you don't want to get lost, simply because there's no cell signal, after all.
Fortunately accessing Google Maps offline is easier than ever, and in most cases won't require you to actually do anything. Considering how valuable a navigational tool it is, those offline maps can come in handy. Especially if you plan on doing some traveling over the holidays.
It's understandable if you'd rather download your maps manually, rather than rely on Google Maps functioning correctly all the time. Fortunately this is incredibly easy to accomplish, and can be done in two different ways. The most effective way is as follows:
This page uses v9.7.0 of the Mapbox Maps SDK for Android and v6.4.1 of the Mapbox Maps SDK for iOS. A newer version of the SDK is available. Learn about the latest version in the Maps SDK offline documentation for Android and iOS.
