ParaGeo Examples

 

In this section several examples are discussed. Those comprise specific examples that can be used as a guidance on how to set up specific ParaGeo data structures or typical ParaGeo application models. As opposed to the ParaGeo Tutorial Examples section, a complete description of the datafile is not provided, thus focusing only on the relevant data structures.
