Geotagging photos and creating map

I’ve been asked to create a map of people working on a project in the UK.

They want everyone to send a photo of themselves that includes geotag data, and then create a map of their locations by uploading the photos.

Can you create a Google Map to do this?

Also, how easy is it for people to find out if the photos they take include geotagging?

I apologise if this is the wrong forum for this question.
