Map format

The freeciv map format is quite simple. In theory it is even possible to edit it by hand.

The map part of a savegame starts like this:

[map]
topology_id=1
width=78
height=52
have_huts=0
temperature=50
alltemperate=0
is_earth=0
r0sx=43
r0sy=39
r1sx=2
r1sy=38
t000="aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
t001="          t   t                 t      t t       t f     t       t           t"
t002="                                                                              "
t003="f                              tffmtt     fmt                                 "
t004="ttt                      tft  fdmmmmmtt  tmt                               ttt"
t005="gfff                   fpgf   fdmttfmpfspgpg                           sssggpm"

Terrain identifier

Single-character identifier used in savegames. This must be unique for each terrain, and changing it will break savegame compatibility.
