Visual programming languages are nowadays commonly accessible in software of geographic information systems. In this article, a comparison of two different visual programming solutions in the area of geographic information systems is presented: the ModelBuilder in ArcGIS Desktop 10 and the Workflow Designer in Autodesk Map 3D 2011. The visual programming introduces a possibility of constructing several steps of spatial analysis as a work flow on geometric and attribute data. It is especially useful for users without specific knowledge of classical textual programming languages. In this article a practical application of model for batch processing is presented on example that demonstrates the generation of digital elevation models. ArcGIS software offers an extraordinary opportunity of exporting the final graphical model to Python programming language. An output script in Python can serve as a start point for the sophisticated algorithmic solution. All of the above mentioned techniques are described in detail in the following separate chapters.
