How to edit elevation data?

Hi,

So my Instinct took some incorrect measurements at one point, probably the sensor was blocked...altitude dropped suddenly to -22 meters.

In total I have a number of waypoints with incorrect altitude stamps, how could I correct that? I have the correct data more or less from the topo maps.

Thanks,

Adam

... or simply enable the option Elevation Correction on the page of the concerned Activity in Garmin Connect Web.(just under the wath photo on the right side). It will recalculate the elevation profile…

You might try http://garmin.kiesewetter.nl or https://www.fitfilerepairtool.info

Or zip the FIT file and attach it here. We'll take a look at it.

Hi,

I'm having trouble syncing my run from today, and cant seem to repair the file via the suggested websites I've researched (likely because I'm on a Mac). Any help would be greatly appreciated.AABA2652.FIT.zip

Thank you, I have just had some time finally to check. Unfortunately when I try to convert my fit file to csv the page errors out... Thank you.

Can you zip the FIT file and attach it here?

Both hikes have 2 negative spikes, not sure why. I know Instinct is famous for having a not ideally placed barometer but I had no such issues in the past year. Both sections should be more or less flat.

As to why this might be happening (assuming your watch isn't defective), there are some support documents here:

As mentioned, you can view the data on Garmin Connect Web using the elevation corrections setting. If you want to actually change the elevation data that is in your FIT file, I can do that using FFRT. This can correct elevation data through the comparison of a public GPS / Elevation database. I have done this on these. Essentially the same as doing it on Garmin Connect.

Here's the before and after of the Julianus hike.

Thank you...the reason for not enabling autocorrection in Connect is that I want to export the file into 3rd party apps like Locus. I will check later but I am sure its OK, so thanks again :)
