Adding gps info on a photo taken...

I used to enable the gps function on my android phone for photos.

What I wish to do is to make a google map showing the track and photos when sailing around.

few experiences to be shared:
1. google map: you can create a own map, and import your photos. Trick1: google map does not support direct import of google photos.(why????)
Solution: you can greate a google blog and import photos to to blog. So, when you import photos in google map(the one you created), you will be able to "see" these photos.
Trick2: Even with photos already geotagged, you won't see the photos on the map, google map will put these photos on the nearest spot. You can't add photo without creating a mark on google map.

So, not exactly what I wish to have, I turn to google earth. It seems
google earth can add a photo base on their gps tag.

I still have few photos from friends or there was no gps signal when the photo was taken. So, need to add manually.
I did search on how to add geo info on internet:
 1. there are softwares which can add locations to photo base on the track you provided. it will match the time stamp with location.
I don't have track.
2. some one says you can add location info with google photo: first, it can only be done for album, the info will not be added to each photo, and you can't add gps info(lat, lon), you can only add "location".

So, since the gps info is in the metadata of photos, I will need to access EXIF data. There are several SW able to do this. I wish to find one can modify gps info by simply point out the location on map.

A quick search:

Also I noted this: http://www.geosetter.de/en/main-en/
Geo setter require IE 10, but this is for interacting with google map/earth, it also means it has more map functions:


So, I will give it a try...

I download the installation file, after installation, it would ask for some update, since geosetter use an other sw to write exif data.

Once you open your photo folder and select a photo.
select a position on the map, and find the little mark to assign to selected images.
Then use file/refresh to write info on to the image.
That's Done!!
Great!!
