1/18/2024 0 Comments Kobo collect and odk collectI’ve found 100m+ differences but that’s on a Samsung Galaxy Note 4 with slow GPS fix - sometimes the camera records the previous location in the geotag even though it indicates a new fix, which is really unhelpful when you download the data!. Worth an experiment - compare the EXIF geotag with the Geopoint information from ODK Collect to see what the variance is (on a decent sample size, more than one phone), and maybe you can decide from there. I know this slows the process down slightly but for the quality of your data, add the question! You can set the visibility of the geopoint question to be dependent on the respective image (use Relevance), so that if the enumerator doesn’t take the nth picture they don’t have to locate the non-existent image… I would recommend using a Geopoint question directly after each photo capture (I don’t think there is yet a background that can be triggered as specific questions using XLSForm as says). Unless you have a relatively new phone with fast GPS positioning, you might get variable results (and if your enumerators are using their own phones, add that to the mix). Choose the GPS question form and tap get selected. Open the ODK Collect app (or Kobo Collect app) on your phone, and tap get blank form. To learn more about these two please feel free to view our post that has been. You could use either KoBoCollect android app or the ODK Collect android app to collect data for your survey project. Whilst recognising that this issue is marked solved, to add a note of caution - I have previously relied on Geotag data from the Camera and sometimes found the accuracy unreliable. Collect GPS Data using your Mobile Phone. Can we use both ODK collect and kobo collect for the same project/same questions does this have effect to data exporting or data analysis Yes. Since I’m using PowerBI, i might be able to do that in PowerBI (i’m not sure, i might have read something about it).Īlternatively, you could do something like I suggested here using the REST Services, but that could be quite convoluted. If you have some technical experience, you could write a script to extract the geo location from each image and append it to the submission - either posting it back to the submissions on the server or just locally on an export of the data. Is there a way to have the geopoint question hidden in the same page as the photo question? That way it would record automatically. I understand your suggestion and I have a followup question. I would suggest adding a geopoint question alongside each image question so that the enumerator can at least explicitly set this each time they take a photo. Hi unfortunately this is not something that XLSForm supports.
