Guest Posted February 11, 2015 Share Posted February 11, 2015 Currently the altimeter only shows "baseline" altitude (sea level on Kerbin, Eve, and Laythe, base elsewhere), which is fairly useless most of the time because parachutes deploy based on ground altitude and knowing how far you are from the ground is crucial to successfully landing. At the moment the only place you can see your ground altitude is within certain IVAs (which are generally useless to begin with because KSP strives to starve the player of information). Therefore, it make sense to have the altimeter on the main flight view be able to show the ground altitude as a different mode, just like when clicking the velocity indicator on the navball.

Tuareg Posted February 11, 2015 Share Posted February 11, 2015 it WOULD make sense and thats exactly why it will not make it into the game like many other things... Link to comment Share on other sites More sharing options...
nightingale Posted February 11, 2015 Share Posted February 11, 2015 So basically, Diazo's Landing Height for stock?Certainly makes sense to me. I remember my first Mun landing attempt when I crashed into the surface at 100m/s because I thought I still had 3 km or so to go. Considering at the time I didn't even know about quicksave/quickload... well you could say I was somewhat upset at the realization of what was going on.

Guest Posted February 11, 2015 Share Posted February 11, 2015 (edited) So basically, Diazo's Landing Height for stock?Somewhat, but just using the stock radar altimeter for altitude, no need for fancy parts-based altitude.

Nemrav Posted February 11, 2015 Share Posted February 11, 2015 so....IVA's are useless, and I hate that... so let's get rid of the one advantage ivas have !!! Excellent idea everyone !!11!!Other than that... sure, people might not be able to handle the higher resolutions to actually see the instruments, so it would be useful Link to comment Share on other sites More sharing options...
cpast Posted February 11, 2015 Share Posted February 11, 2015 More like "why make us use IVAs for this information?" I don't see why AGL altitude should be specific to IVA. While I don't love that things like apoapsis altitude aren't available in non-map mode, I can see the reasoning (map mode is for stuff to do with the orbit, flight modes are for when you want to control the craft at a finer level of detail than "use my currently enabled engines" and "point"); however, I don't see why IVA is uniquely suitable for the radar altimeter.

Sonny_Jim Posted February 11, 2015 Share Posted February 11, 2015 +1 for the idea that altitude is displayed from terrain when the navball is set to surface mode and sea level when in orbit. Makes much more sense. Link to comment Share on other sites More sharing options...

Brotoro Posted February 11, 2015 Share Posted February 11, 2015 I approve of being able to switch the altimeter from MSL to AGL. They could invert the colors of the display (to white on black) to make the change Really Obvious. Link to comment Share on other sites More sharing options...
Stormweaver Posted February 11, 2015 Share Posted February 11, 2015 It'd be more interesting to have parachutes deploy based on height above sea-level, and unlock a not-inexpencive radar altimeter some way into the tech tree.....but where you have one, yes, it should be on the HUD somewhere.

Red Iron Crown Posted February 12, 2015 Share Posted February 12, 2015 (edited) Agree with this suggestion 100%, when in surface mode AGL is the more useful information and should be available in the main flight view as well as IVA.it WOULD make sense and thats exactly why it will not make it into the game like many other things...Do you have anything constructive to add? Because that post is simply worthless. Edited February 12, 2015 by Red Iron Crown Link to comment Share on other sites More sharing options...
Alshain Posted February 12, 2015 Share Posted February 12, 2015 (edited) I agree with the suggestion, but I'm afraid at this point they would probably add it as a function of the Engineer. Ground level altitude is a complicated two variable subtraction problem after all. Edited February 12, 2015 by Alshain Link to comment Share on other sites More sharing options...
Renegrade Posted February 12, 2015 Share Posted February 12, 2015 Also agree.Actually, is it even possible to determine altitude above sea level on a planet that has no atmosphere? AGL is easy to do with radar, optics, or laser rangefinders or such.. but sea level measurements usually rely on barometers, no? Link to comment Share on other sites More sharing options...

AGL is easy to do with radar, optics, or laser rangefinders or such.. but sea level measurements usually rely on barometers, no?I believe it is the other way around. The sea level is the standard for which atmospheric pressure is measured. Presumably if you had a defined standard sea level for a body and knew the altitude of the ground, radar mapping could tell you the ASL without a barometer by simple addition, but that process requires the surface altitude first, which is why we should have access the that data!

If both are to be available, clicking the altimeter (as suggested by regex) sounds like a perfectly good way to handle it, especially as that's how the speed indicator on the navball works.Would kill fewer newbies too Link to comment Share on other sites More sharing options...
cicatrix Posted February 12, 2015 Share Posted February 12, 2015 Technically, radar/laser altimeter is the only reliable instrument that is available on the planets with no atmosphere. There is simply nothing else that can tell you how far is it. So, the baseline altimeter is an artificial thing that is used by the game engine. The real thing is radar / barometric altimetry.

AGL is easy to do with radar, optics, or laser rangefinders or such.. but sea level measurements usually rely on barometers, no?In KSP "Sea Level" on airless/oceanless bodies is essentially the base sphere radius around which all terrain is measured from. It is useful for orbital calculations (75km up, or whatever) but is essentially worthless for landing.I agree with the suggestion, but I'm afraid at this point they would probably add it as a function of the Engineer.

tntristan12 Posted February 13, 2015 Share Posted February 13, 2015 (edited) I've been pulling for this feature for a long time. I think I would go one step farther and say "give the altimeter a datum toggle like the speedometer has." For example, the cycle might go:1) distance from surface of planet.2) distance from center of planet.3) distance from currently selected target (for docking, since the altimeter is basically useless when you're trying to dock)For bonus points, tie it to the speedometer datum toggle, so 1 corresponds to surface mode, 2 corresponds to orbital readout, and 3 corresponds to target readout.EDIT: It'd be really nice to toggle them independently, but have them switch together when the transition is automatic (like when going from surface to orbit mode)Tangential aside: Heck, let's make the Pe and Ap readouts in the map menu measure from the center of the planet instead of sea level, because that makes absolutely no sense whatsoever!

Above ASL makes sense anytime you need to have an idea of how much clearance you have from hitting the planet and it's how most Low orbits are described. You only need Pe from center if you're doing math, in which case adding the body radius is a trivial step Link to comment Share on other sites More sharing options...
cicatrix Posted February 13, 2015 Share Posted February 13, 2015 2 corresponds to orbital readoutImagine you're in a real spacecraft orbiting the Moon. How in the world you would determine orbital readout? The only way you can measure the distance to the surface/target is by using radio or laser beam. No 'orbital readout' for you.

Still doesn't make much sense for heliocentric orbits though, since you never actually come close enough to the sun to worry about crashing into it.Imagine you're in a real spacecraft orbiting the Moon. How in the world you would determine orbital readout? The only way you can measure the distance to the surface/target is by using radio or laser beam. No 'orbital readout' for you.You're preaching to the choir on that one. Yes, it is unrealistic, and as somebody who is taking a graduate level course on spacecraft navigation I can attest to the fact that determining a spacecraft's position in space is no trivial thing. However, keep in mind that nearly everything about KSP's UI is designed to make it accessible. Hell, I don't think even Orbiter went into that level of detail - requiring you to determine your position using celestial navigation or GPS or whatnot. I think something like that is a reasonable break from reality.Besides, how exactly does pinging the Mun with a laser beam tell you where you are at relative to the datum? By that logic, the system is already broken anyway. Also, I do agree that surface mode should give you the radar altitude anyway. Link to comment Share on other sites More sharing options...

Actually, there's no big difference if its radio or laser - they both are just electromagnetic waves. So, you can use either to determine how far down the surface is (or your target is), but you cannot tell how far the 'baseline' or 'sea level' are or how far is the planet center. What I mean that it's only logical to change the altimeter readout from 'baseline' to 'surface'. Link to comment Share on other sites More sharing options...
