The Southern Cross of the Russian Empire, and A Neat Trick with Mapillary GPX FIles

於 23 六月 2018 由 apm-waEnglish發表。 上一次更新時間為25 五月 2019。

You learn something new every day. Monday I traveled to Serhetabat, on the border with Afghanistan, and collected Mapillary imagery en route that is now being uploaded (please be patient, the Internet is slow here). Mapillary also collects accurate GPX files along with the images, and I have learned that if I copy them from the SD card onto my computer, pull them all into EasyGPS, and save them merged as a single file, I have an accurate GPS trace of my entire route. I may be a slow learner, but I’m at least still learning!

On a hilltop in Serhetabat one finds one of four crosses erected by the Russian Empire in 1913 to celebrate the 300th anniversary of the Romanov dynasty. The four crosses marked the four farthest flung points of the compass, and this was the south compass point. The other three have been taken down but this cross survives.

To be more accurate = Mapillary makes a folder for each sequence. In that folder there are the jpg files of 1 sequence and one gpx file.

Yes, correct, and the easy way to get at them (if you have a Windows-based computer) is to use Windows to search for all *.gpx files on the SD card, move them to a single folder on your computer, pull them into EasyGPS, and save the result as a single file. Here is the one I was talking about: osm.org/user/apm-wa/traces/2730630

And no Strava there, I suppose ?

I don’t run or cycle so would not know.

Looks like there are a few in Ashgabat, at least: Strava in Ashgabat

If you are into GPS, I even have more for you to learn.

Why don’t you log with https://play.google.com/store/apps/details?id=de.geopp.rinexlogger

and postprocess into a gpx file ?

With my Samsung S9, the rinexlogger works in the background.

Dear Philippe, It looks interesting, but I am already using Pocket Earth on my iPhone to collect GPS traces when I am not using another device, and it works pretty well. Pocket Earth traces can be exported as GPX and e-mailed to myself for upload to OSM. apm-wa
