Q:

How to use GPS log from Nikon D5300?

I have turned on GPS tracking in my Nikon D5300. It generates a CSV text file with some data.

Found the website that explains what each field means:

GPS: NMEA sentence information

How can I use this data to place it on the map?

A:

You can visualize the GPS log on different places. For example Google Maps.

Go to in My Maps
New map. If you do not see Import you can add layer and there import GPS logs
Import. There you can add CSV, KLM, GPX files

If you want to convert your log in different format you can use variety of software. I use GPSBabel, you can check this answer
This is the command:
gpsbabel -w -t -i nmea -f C:/tmp/a.csv -o gpx -F C:/tmp/a/a.gpx

Do not use CSV format, instead select NMEA
Edit: You can view images on the map if you use Maps module of Lightroom. And if you export them as jpeg or have them in this format you can use Google Photos or Flickr Map module to visualize them on the map
