Spatial Analysis and Modeling Tool Version 2 (SAMT2), a spatial modeling tool kit written in Python

SAMT2 is a complete re-implementation and enhancement of the Spatial Analysis and Modeling Tool (SAMT) in the form of a Python module. Implementation as a Python module offers great flexibility due to the wide range of scientific Python modules that can be used without having to transform the basis data types. SAMT2 can be used as part of a Python script even in parallel processing at the computer cluster for large simulations. Its graphical user interface is similar to that of SAMT, but it is easier to adapt and enhance. In addition, SAMT2 can be used together with IPython notebook to combine the readable source code, documentation, and visualization to a new style, called Open Science, to include stakeholders in modeling. The paper focuses on the new graphical user interface based on QT and the implementation of SAMT2.
