The TerraME environment implements the nested-CA model and services for spatiotemporal data analysis and management, model development, simulation, and assessment.

There is a GUI library called LuaAllegro.

As I can see until now, the other applications decided to implement a simple time scheduler, and give to the behaviour pore complicated time-dependent decisions.

TerraME works with topological spaces. It has advantages and disadvantages over geometrical spaces. First, it can represent proximal spaces

When we have simple geometrical objects, such as rectangular or hexagonal cells, it is simple to compute geometrical relations. TerraME stores both topological and geometrical relations of cellular spaces.

But when we go forward and represent complex spatial objects, the geometrical relations became so complex that topological relations are unavoidable. Future versions of TerraME will work with this kind of object.

The scale in TerraME can be used to implement an observer??
