You can sell survey data in Starfield at a few different buyers, but the best one for profit is Vladimir Sall on The Eye.

Main place to sell survey data

  • The best place to sell survey data is Vladimir Sall on The Eye , the Constellation station orbiting Jemison in the Alpha Centauri system.
  • To access The Eye, you need to progress the main story: finish “The Old Neighbourhood” and start “Into the Unknown” so you can travel there.
  • When you talk to Vladimir, use the dialogue option along the lines of “I’ve got some survey data for you” to open a normal sell menu where all your completed survey data notes appear.
  • Vladimir pays the highest rates for survey data (around a quarter of the value listed on the note, improved further with the Commerce skill), so he’s the go‑to if you’re min‑maxing credits.

Tip: If the survey‑data dialogue does not appear at first, exhaust all of Vladimir’s conversation options once, then back out and talk to him again; players report that this unlocks the survey‑data line.

Other places you can sell survey data

If you can’t or don’t want to go to The Eye, you have alternatives:

  • Trade Authority kiosks and vendors
    • You can sell survey data to the Trade Authority like any other item, from the Notes section of your inventory.
* Trade Authority kiosks/posts are found in places like **New Atlantis (Jemison)** and **Cydonia (Mars)**.

* They pay **about half of what Vladimir does** (roughly 12.5% of the listed value), so it’s convenient but less profitable.
  • Phil Hill (LIST rep on Mars)
    • Once you start working with Phil Hill , the LIST representative in the Broken Spear bar in Cydonia , he can also buy survey data.
* He only buys **completed survey data for habitable planets** , and he pays about **half of Vladimir’s rate**.

Requirements for selling survey data

  • You need 100% survey completion on a planet for the survey data to turn into a sellable note: this means scanning all flora, fauna, resources, and relevant points of interest until the planet shows as “Surveyed” on the star map.
  • When fully surveyed, the planet’s data appears as a Note in your inventory, which is what you sell to Vladimir, the Trade Authority, or Phil Hill.

TL;DR:

  • Best credits: Vladimir Sall on The Eye.
  • More convenient but worse rates: Trade Authority kiosks/vendors.
  • Special case: Phil Hill in Cydonia for habitable worlds only, at reduced payout.
