Made my first steps in that direction.
Set sail for Synuefe TP-F B44-0 to check the ancient ruins there.
Scanning every system on my way, found a planet with biosigns and checked it out. Was lucky and stumbled upon some Frutexa and found 3 locations not too far apart to sample.
There are a few questions that arose during this:
1) What does it mean if the FSS scan tells me under Features "Biological (3)"? Are these three different species?
2) The DSS seems to show different colours after a completed scan. What do I have to look for if I want to find some of theat green (well, sometimes) stuff?
3) Does the flora show up on the SRV scanner?
As 0threeleven says regarding point 1) yes 3 species on the planet, paging through the DSS screen will show you the areas where the different species may appear...note the may, not necessarily will due to some sub-requirements. For instance some species will only be found on mountains but the blue will often encompass both mountains and plains, the DSS notes suitability of environment but not sub-requirements like sandy ground or rocky ground etc, these are things we often need to learn for ourselves either by asking or plain experimentation.
2) the different colours are misleading and only reflect the ground geology and not bio density, it's not a heatmap but a location map showing suitable environment like temp and etc, you won't necessarily find the indicated bio everywhere in the blue area, but the different colours are of no help really in finding them, it's annoying but once you start learning about the bio it does become much easier.
Yes
Yes, kinda. It will show as a long narrow streak but could be a long ways off
Don't forget if you get more than 2.2 kilometers away from your ship, it will leave and go into orbit and you'll have to recall it through your crotch panel.
3) Really 3 is a yes and no reply. It will show old Horizons type bio, brain trees, bark mounds and etc, these often appear on the Odyssey planets, but it won't show the new Odyssey only bio, it shows the old bio due to the mineral deposits on them, so the SRV scanner shows mineral deposits only, not bio, but because the old bio has mineral deposits associated with them you can use it to find them, but it will not help you with the Odyssey bio. Hope that's clear for you.
