LUE data model and modelling framework

Output of an example model built with LUE. Time increases from bottom to top. The sheets represent amounts of biomass and the lines the location of wandering deer.

LUE is software for storing and manipulating large amounts of information for large collections of objects. The software currently mainly used in the context of forward simulation modelling of biological and physical systems which are represented by discrete objects and continuous fields. Kor de Jong and colleagues tried to make the software as generic as possible, with the goal to make it useful in other domains as well.

The latest addition to LUE is a set of operations for computations that involve potentially very large grids of information. These operations can be called by the user from a Python script, and can optionally make use of compute clusters. For example, a simple statement statement like my_slope = slope(my_huge_elevation_grid) calculates the slope of a digital elevation model and runs unmodified on laptops as well as on multiple cluster nodes.

LUE is spinoff of research projects at the departments of Physical Geography, and Information and Computing Sciences, and is in active development. For more information, visit the or contact Kor de Jong. A is available.
