By the time you can collect most of these you can just scan for them in the world while playing and detect them nearby (same for mercer spheres and sommersloops). It's unlocked through pretty easy research tiers.

There is a much more informative map if you google Satisfactory Tools and look for the interactive map. It also includes the items and/or power required for each.

Save scumming is also a way if you're going for the achievement.
Same goes for Mercer Spheres and SomerSloops.

Nice thanks
