Algorithm for generating continents/islands

[Ralfonso]

Hello,

currently i'm programming a mapeditor. i want to include some nice scripts, which generate some islands/continents or other interesting shapes. the algorithm only need to tell me, if to set land on the field (x,y) or not. But in that direction i have no experience.

so if you can tell me some good internetsites or names of algorithm which can be used for this, i have a point at which i can start with the search. some example are also welcome, the programming-speech doesn't plays any role to me. so pseudocode will also be good.

i'm thankfull for every help.

See this link.

It portrays some methods for automatic 3D terrain generation.
You can easily adapt it to 2D if you decide a height threshold.
