Get more understanding of

– Data acquisition

– Software concepts

– Data concepts

Practical work

– Install working tools and data

– First tutorial in HydroVISH

– Look at some concrete data

What are we doing today?


Tomorrow:

– Work on a concrete example project

– Doing the major processing steps togetherwith the HydroVISH tools

Day after tomorrow:

– Continue on that

– Do a GIS workflow together in ArcGISwith data exported from HydroVISH Viewer / KomVISH

– Work on/present other topics of interest e.g.: data connections to other pipelines

What are we doing thereafter?
