Introduction

iLand is a model of forest landscape dynamics, simulating individual tree competition, growth, mortality, and regeneration. It addresses interactions between climate (change), disturbance regimes, vegetation dynamics, and forest management.

iLand is a research tool already used by a growing number of scientists in the US and Europe. The iLand software is released under the GNU General Public License and freely available.

The iLand wiki with 120+ pages of documentation, links to the download package and much more is located here.

the source code

Qt toolkit

iLand uses the cross platform C++ toolkit Qt. Qt is available for Windows, Linux and Mac platforms (along several mobile platforms like Symbian, Maemo, and others) - so you are not locked in with regard to operating systems. The Qt framework is open source and offers lots of functionality beyond the graphical user interface.

Database

iLand uses the SQLite (http://www.sqlite.org/) database. This is a leight-weight open source database that requires no installation, is cross platform and has the reputation to be very fast. SQLite stores the all tables of a database within one single file. This approach could get quite handy for the storage of model outputs.

Subversion

The iLand source code is stored in a subversion source code repository. The public SVN-repository (through WebSVN) is available on the net: http://iland-model.org/publicsvn/. Note that there is also a "private" SVN for portions of the model that are not published yet.
