I can't see GPS data in the App

The GPS data can be delayed between the time the Moments are built and the time you receive the GPS addresses on your photos. We are working hard to make this better.

Restart your App and check if any additional GPS locations are reflected. You won't be able to obtain GPS-addresses to your Moments if you don't have access to Wi-Fi or 3G/4G on your Smartphone. To get GPS positioning indoors is unfortunately always a challenge.

    I have the same issue. In 6 days I have not had a single moment reflected with GPS data.

    In two months of use, I have never seen any GPS data associated with any image or moment. No location is displayed in the app, and none of the images downloaded from the app appear to be 'tagged' with any GPS information.

    How is GPS location meant to be displayed? Should it be displayed in the app? Is it added to the downloaded photographs?

    I'm interested to hear that other people are seeing some kind of GPS information, because I'd started to believe that it was an unsupported feature.

    Hi guys,

    We are doing a number of updates to improve the overall performance and user-experience of the Narrative photo pipeline. Unfortunately, this means that currently the geographic tagging of Moments is being held up, but once the maintenance work is done, all old and new Moments will be updated automatically with the recorded GPS data. Thanks for your patience.

    Kind Regards,

    I also had the same issue, but after a few days, some of the moments had locations added,

    Location data started showing up for some Moments a little while ago, but more recent Moments don't have it.

    I suspect that there are two things going on. One is that the GPS in the Clip may simply not be able to capture GPS data for all images (I've seen hints that like many GPS devices, it doesn't work well if line-of-sight to GPS satellites is not available, i.e. obstructed by tall buildings or when inside). The other is that computing location from the raw information stored by the Clip is resource-intensive, so Narrative may be turning off that feature when their servers don't have enough spare capacity. This is speculation on my part, but it seems to fit with what we've seen.

    If location data is dependent on the amount of server resources Narrative can bring online at any moment, then that's one reason why I'd really like to see Narrative offload those particular computations into the Uploader, so that location data can be computed locally. However, their gameplan may call for keeping location information as a part of the 'added value' for their subscription-based service, so they may not have an incentive to enable client-side processing.

    @Angus M. I think this article https://support.getnarrative.com/hc/en-us/articles/202246618-Why-Do-I-Need-The-Narrative-Cloud-Service-To-Get-My-GPS-Data- fits in line with what you are saying :) Narrative's geolocation feature relies on a so-called Software Defined Radio approach, which means that the GPS-processing is split between the Clip and the our Cloud Servers. This is primarily done to prolong the battery life of the Clip, since the main idea of our Clip is to lifelog our lives.

    @Ariq Rob. Glad it worked out for you. Again, please always feel free to reach out to us if you have any issues and we will work to solve it. Have a great day!

    Thanks Angelyn. Yes, I'd seen that article and I understand the SDR approach, and the importance of offloading GPS processing to save power on the Clip.

    I'd be curious to know whether Narrative will ever support GPS processing on user computers, rather than the Narrative Cloud Servers. The advantage would be that if this processing was done on the user's machine (by the Uploader software, for example), it would reduce load on Narrative's Cloud Servers. However, I imagine that Narrative may have plans to keep GPS data as part of the "added value" that comes with a subscription.

    There is a GPS decoder for the narrative data on github

    The only Narrative-related projects I've found so far on Github seem to be fairly early-stage. https://github.com/ruins/offline-narrative seems to be the most advanced/ambitious, but doesn't have GPS decoding yet.

    I just searched https://github.com/search?q=narrative+clip. If you know of other projects that don't show up in this search, I'd be interested to hear about them. Thanks.

    @Hi Angus M. We will update you when we have new developments coming up! We are working on improving the GPS processing and momentification. The projects done on Github are not sanctioned by us, and we have no means of ensuring its security, so please do it at your own risk! Again, feel free to reach out to us if you have any other queries. Have a great weekend!

    I don't understand. Why is the 3G/4G wireless mentioned. Is the GPS taken from your cell phone via the mobile app? How is this possible? There is no bluetooth connection

    When a photo is taken they record the GPS data using an CellGuide ACLYS radio module. In order to allow the device to function with minimal battery usage they are not decoding the signal on the device. Instead they take a GPS radio recording (SNAP) of the data and store it in a file(Off-Board Positioning Using an Efficient GNSS SNAP Processing Algorithm - http://www.cell-guide.com/technology/resource-center.html). Narrative processes the recording on the server to then generate a location. In order to improve accuracy you join the GPS data from multiple recordings together to then create a statistical average of where the device is located. The SNAP data is not inherently reliable, but when you join multiple SNAP's you can then produce a more reliable positional fix and track.

    This has nothing to do with 3G/4G. That comment is instead referring to viewing the GPS data on the app. The photos are tagged with GPS coordinates and they are doing a web service lookup to get the location name.

    If you want to see what the app is doing. Download Fiddler web debugger and setup your phone to proxy through it. This will show you exactly what is going between the app and the server. You will see that it is a simple location lookup based on the coordinates in the reference.

    Update: @Angus M, looks like the project that had the GPS decoding was pulled. I sent the primary developer an email asking why. I have been using it to successfully geotag my clip photos for several months. I was not a big fan of uploading all my photos and didn't want to marginalize the effectiveness of the clip by losing the GPS data.

    Thanks for the info. I still have one set of moments with no GPS data. I was indoors the whole time. Perhaps that has something to do with it (the previous post also mentioned issues while indoors)?

    Hi @Chris Yes indoor moments are more likely to have no GPS data /Ange
