Description
  • Data flow diagrams (DFD) are one of the oldest graphical representations in informatics. The data flow diagrams can be consider as visual programming language (VPL). Nowadays, geographic information systems (GIS) have some graphical environment that assists in the designing of flow chart model. The article brings an overview of notations and formal semantics for data flow diagrams in GIS. The survey contains software ArcGIS for Desktop 10.2, ERDAS IMAGINE 2013, IDRISI Selva and AutoCAD Map 3D 2014. Beside the commercial software, the open source QGIS 2.2 and its component Processing Modeler is mentioned. The article concerns more to the graphical notation than the amount of functionality. The graphical notation is important from the point of perception and cognition. The main task of data flow diagrams is to support the batch processing data. The next function is a %22graphical report%22 of steps of processing. From the point of these two tasks, the graphical notation is important. For all that purposes, it is necessary to use cognitively effective visual notations. Cognitively effective means optimized for processing by the human mind. An optimized notation helps to user very quickly understand to the diagram.
