Hi Reuser

I would love to help you, but I may have to disappoint... if you thought I used some kind of data dump to create my maps, then I have to correct you Instead, I used Eve-Map (a downloadable tool by FFET, and then transposed the information onto Visio.

If you don't need ank kind of data dump, mail me (ombey @ o mbeve.co.uk) and we can talk further.

Cheers.

Mail sent!

I would like to see how I go about auto-generating a map dump from the DB, but I don't even know where to start! I'll try dropping them a line, asking on the EveO forum didn't get a response.

Hi Ombey,

A few points:

Generating a map from the db data should be as easy as plotting the coordinates in a 2D plane. Instead of using X/Y coordinates use X/Z.

To find the distance between any two objects in eve use the formula for the length of a line segment in 3 dimensions:

distance = sqrt[(z2 - z1)^2 + (x2 - x1)^2 + (y2 - y1)^2]

Since the coordinates in eve are at a resolution of 1 meter per unit it's very easy to calculate the distances in any unit you like:

;; DISTANCE-IN-METERS = SQRT((X2-X1)^2 + (Y2-Y1)^2 + (Z2-Z1))
;; DISTANCE-IN-KM = DISTANCE-IN-METERS / 1000
;; DISTANCE-IN-AU = DISTANCE-IN-KM / 149598000
;; DISTANCE-IN-LY = DISTANCE-IN-KM / 9460730472580.8
;; (au = astronomical unit)
;; (ly = lightyear)

I have a dump of the coordinates of all regions, constellations, systems and celestials (suns, planets, moons, belts, stations, gates) if you would find it useful. Be aware though, the number of results is enormous:

Code: Select all

;;   There are:
;;      67  Regions             (         2,244.5 pairings)
;;     786  Constellations      (       308,898   pairings)
;;   5,186  Stations            (    13,447,298   pairings)
;;   5,431  Suns                (    14,747,880.5 pairings)
;;   5,431  Solar Systems       (    14,747,880.5 pairings)
;;  14,334  Stargates           (   102,731,778   pairings)
;;  46,172  Planets             ( 1,064,542,082   pairings)
;;  56,494  Asteroid Belts      ( 1,595,786,018   pairings)
;; 234,651  Moons               (27,530,780,552   pairings)

The pseudocode for such a program looks something like this:

Code: Select all

;; for each thisLine in readFromFile
;;   read thisLine's tokens
;;     read nextLine
;;       calculate-distance
;;       write-distance to writeToFile
;;     loop nextLine
;;     ;; we are past the end of the list
;;   loop thisLine

I'd be happy to help you with this if you like. I like the idea but am too damned lazy to do the work just for my own benefit... Send me an evemail or a pm here and we can work it out.

Keep up the good work!

Hi val

Sorry for the delay in replying, I have been away on holiday.

Thanks for the post, that looks like a lot of work!

To be honest, I am unlikely to start it all again programatically, because a) I wouldn't know how to troubleshoot it if I got stuck and b) I've done all the hard work, and there's not much point me starting again unless people *really* want the layout to match the in-game layout... and that brings a whole host of new problems with it.

Could be useful when planning a route, when planning an escape and whatnot.

Neat idea! The only trouble with this is that unless this data is published somewhere, I would need to visit every single system or get people to send me in the data and hope they've done it right.

I really like it though... a lot.....hmmm. I might just start recording distances on my travels anyway and see what happens

In terms of informatics the distance between gates might be better represented by scaling the lines that connect the systems, or annotating the lines with a tiny distance figure.
