The aim of the course is to extend the analytical skills of students in the processing of environmental spatial data. The topics within course are not focusing on theory of spatial ecology but mostly on practical tasks of data processing in free open source GIS software. An important aspect of the course is to selection of the software which is freely available and/or have open source code. The course uses knowledge of ecology and landscape ecology (individual tasks are within domain of ecology/landscape ecology). After completing the course, the student will be able to process spatial data in open source GIS and gain a basic overview of the possibilities in the current free GIS tools.
