A helpful Delta V map?

[maceemiller]

Hi all. Was just browsing around on the internet when I came across this interactive dV map. I actually like it but whats your thoughts on it?

It's interesting, and appears to be well coded.  I find the subway maps to still be more convenient.

I use the subway maps too however this could be a useful addition. I like the way it breaks down the dV into separate stages without having to do the math myself

Yes it's quite nice.

I had quite a hard time to understand the rocket and flag icons

But even the "realistic" value is very overfueled.

Ahh that was what I was wondering.....the fuel levels. Mind you as a sandbox player predominantly I personally think that too much is better than not enough. I also agree that the icons could be better presented.....I've only just worked them out myself lol.

I find it unintuitive, hard to use.  I'd just go with a subway map/porkchop plotter and add what I think are decent margins.

Aside from subway, I usually use this here:

It's soooooooooo good, giving you all the windows, costs and timings ingame. And ofc mechjeb, when I'm lazy.

It's a little unintuitive, but seems to be chock full of very useful information. I'll probably keep this for when I need more detailed things along side my subway maps

You can set the margins for the Realistic and Casual options on the sliders.

 

Surprised by the unintuitive comments, seems to be just click your start point, click your end point and it tells you the dV requirement.  Saves having to add up the numbers on a subway plot.

 

Not sure about some of it's numbers though, for example it says Mun surface to Kerbin low orbit is the same as Mun surface to Kerbin surface.  Surely in the former you need a bit more dV to lift the Pe out of the atmosphere after capturing, and to get to Kerbin GSO from Mun surface it seems to be saying go to LKO and then back up again, not sure if that'd just the display though as I've not tried the manoeuvre to see how much dV it would need.  It's a pretty minor point though.

It doesn't give you the angle for an ideal launch window (which can massively change your dv requirements)

EDIT : I didn`t break it, I mistook Kerbol for Kerbin because it was misnamed, there is no kerbol...

this will get book marked at home.

rep to the coder on this one... who ever it is and is on the forum. it is a good supplement to the subway map.

Seems good for ballpark calculations on simple missions - it throws a lot of answers at you in a single click so time-wise seems pretty easy. But yeah - I can get to orbit with ~3500 m/s, it's budgeting me over 3900. :/ I'll try the "perfectionist" setting where it doesn't give you any extra fuel and just add that manually.

Also - a trip from Kerbin to Eve adds over 100m/s in plane change - why not just match and intercept from whatever angle and just save yourself the fuel? Anyways, I've turned that one off - though I can see that feature being useful for (say) Pol-Bop transfers and so on.

EDIT again: Though it's certainly worth considering plane changes in trips to Eeloo or Dres too - I've had missions out there fail because I planned an intercept when the planes were far out of alignment.
