How to find current biome? (including "LaunchPad" etc.) [Answered]

[Snark]

So, I'm trying to figure out "what biome is the ship in".  Simple, right?

So far, I've found two ways:

• ScienceUtil.GetExperimentBiome
• ResourceUtilities.GetBiome

...and they both work... mostly.

However, they appear to be clueless about the various mini-biomes around KSC.  For example, if I'm sitting on the launch pad and query either of those mechanisms, they'll simply say "Shores".

How do I get the actual science biome of the current ship position?  In other words, "If I were to take a science measurement right now, what biome would it say", including the micro-KSC biomes?

It is actually easy :

Oh!  So that's what Vessel.landedAt is for.

Okay, well, nice to know that not everything has to be hard. 

Thank you for the answer!  Very easy, yes, but it sure wasn't very discoverable (by me, at least).  Would have taken me forever to find that on my own.  Much obliged.

[EDIT]  ...Okay, I spoke too soon.  It's still not quite what I need.

The code in question basically says, "use Vessel.landedAt if it's there, otherwise use the current biome".

public string CurrentRawBiome()
{
    if (vessel.landedAt != string.Empty)
        return vessel.landedAt;
    string biome = ScienceUtil.GetExperimentBiome(mainBody, vessel.latitude, vessel.longitude);
    return "" + biome;
}

...The problem is, it doesn't seem to match what I need.  If I do this on the launchpad at KSC, for example, landedAt is KSC_LaunchPad_Platform, whereas what I actually need is just LaunchPad.

What I mean by "what I need":  I need the biome name that ends up in science subject IDs.  For example, if I take a gravimeter reading on the launch pad at KSC, the subject ID that it ends up with is:

gravityScan@KerbinSrfLandedLaunchPad

...It's pretty clear that the way the game constructs a subject ID is:  experiment ID + @ + body + situation + biome

...so the "biome" that I need, here is just plain "LaunchPad".

Nor can I just do something programmatic, like "parse out the first word after "KSC_".  For example, the ground just east of the launchpad platform gives a landedAt value of KSC_Pad_Grounds, but the resulting science subject ID is still using a biome string of LaunchPad.

I suppose I could try just driving all over KSC with the debugger and seeing what landedAt gets set to, and then build a dictionary (e.g. "if landedAt is 'KSC_LaunchPad_Platform', then the biome is 'LaunchPad', etc.) to do the translation.  But that seems really hacky, tedious, and error-prone (I'm likely to miss stuff) ... surely there must be a better way?

...Okay, was able to find the answer.

It turns out that there's a static function Vessel.GetLandedAtString.  Pass in the value of Vessel.landedAt, and it returns the string that gets used in science subject IDs.

So the algorithm is basically,

1. check vessel.landedAt to see if there's a string there
2. if there is, the answer is Vessel.GetLandedAtString(vessel.landedAt)
3. if there isn't, use the other biome-determining functions
