Why Download Offline Maps !FREE!

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 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~

Just upgraded to iOS17 and checked the new offline maps feature. The thing I like is that you get transit in offline mode. The thing I don't like is that there is no search option. You can browse offline maps. It is almost useless. If you are visiting some city (that you downloaded for offline use) and want to go to some street, how would you find it?

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!

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.

iOS 17, just use my saved maps when I'm in that area without impacting my data rates. If I venture outside of that area, please use the data to populate a new map. Why is "only use offline maps" even an option?

The "Only Use Offline Maps" setting is designed for situations where you have a limited or no data connection. When this setting is enabled, Apple Maps will only use the offline maps that you have downloaded, even if you are connected to Wi-Fi or cellular data. This can be useful if you are traveling to an area with poor or no internet coverage, or if you want to avoid using any data for navigation.

Edit: Additionally, I believe that off-line maps is not used whatsoever when online maps is on. The only current benefit to offline maps is that it will automatically switch to offline maps only when your phone detects that you have no cellular connection. But even with 1 bar of super weak connection, it will still try to use online maps so even that aspect is not very seamless.

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:

I have read up on google map api, and it seems that it is against their policy to use their map offline. On the other hand, the custom markers is something that I am interested in. I am considering to make use of the marker concept to show the status of the area.

Seems like you could use a combination of MapServer as mapping server and openstreetmap as data source (maps for asia are available, but it depends on the level of zoom, precision and update you are willing to work with) and OpenLayers to load, display and render your markers and data.

Google Maps/Earth will only allow you to store 2Gb of map data locally. The API will not let you store any at all. There is no way to use the maps offline. However you can try downloading images from NASA World Wind: it is opensource.

I believe it only shows the offline maps that correspond with the chosen map provider and type in settings. So if you downloaded a VWorld roadmap it only shows it if Application settings->general->miscellaneous->Map provider and Map type are also VWord map.

The wiki contains a short description on using offline maps.

I followed it to the letter but no maps appear on my tablet.

I suspect it has something to do with the path to the maps.

The path mentioned in the wiki does not exist on my Samsung Galaxy 2 tablet.

Does anybody know what place the offline maps should be placed, if the app is very critical to this, or if you can change the path?

The first one being: ./DroidPlanner/Maps/1/, the last one being ./DroidPlanner/Maps/19/. All folders contain subfolders with georeferenced map material.

In DroidPlanner I checked the use offline maps checkbox and I restarted the app.
