In many business decisions and business processes spatial information plays an important role. Although in computer science with the Business Process Execution Language (BPEL) a standard for modeling and controlling business process workflows exists, the instruction set defined by this standard lacks spatial operators. For example topologic operators like \"Touches\" or \"Within\" would be needed for branching business process workflows depending on the spatial properties of data involved. Analogous to so called decision gateways used in the Business Process Modeling Notation (BPMN) for branching workflows by comparing alphanumeric data using logical operators like \"Less than\", \"Equal to\" or \"Greater than\", the introduction of spatial operators would lead to \"Spatial decision gateways\".
