I have a Nextbase 552GW thatis very good quality and GPS. I have tried to follow the instructions to upload the video files and GPS traces using the command line tools however I have never used command lines before.
Is there a set by step guide on how to upload using command lines for absolute beginners?
I have never seen a guide that starts at a low level. There are many many ways of running it, so any guide would be very complicated. Perhaps you should post info about your operating system/version and what you have tried so far. I personally ONLY use mapillary_tools under Linux.
There is also a desktop based uploader that you may like to try. (I have no experience with that)
