Vaclav Petras

My research includes landscape evolution analysis in coastal areas based on space-time cube concept, GIS-based environmental modeling of natural phenomena, web-based spatio-temporal visualizations for communicating research, and finally geospatial software quality assessment, which allows he and other scientists to test the proper functionality of various geospatial algorithms. I collaborate on free and open source software development, most notably, development of GRASS GIS. I believe that open source software is a crucial part of open and reproducible science and that providing my work as open source allows equal opportunities for all scientists around the world to use, critique, and further develop the results of his research.
