Geographic Information Systems (GIS)Geographic Information Systems (GIS) and geospatial applications and infrastructuresinfrastructures are widely used and widely integrated into other systemssystems. Among the most well-known such systemssystems are those based on the Global Positioning System (GPS) and other Global Navigation Satellite Systems (GNSS). They have enabled such diverse applications as automobile navigation systems, smartphones that location-stamp photographs, and military weapon systems that target enemy locations. According to Hahmann and Burghardt (2013), about 80% of all data have a spatial referencespatial reference; i.e. the data can be related to a physical coordinate in a spatial reference systemspatial reference system, or identified by a geographic identifiergeographic identifier. SystemsSystems and their constituents reside in or operate in space and often need to know where they or their parts, constituents, etc. are; where their mobile components go; or where objects observed by the system are. In other words (Longley et al. 2015): “Almost everything that happens, happens somewhere. Knowing where something happens can be critically important.” Extending this observation, potentially the system(s) and their associated constituents require synchronization of their activities and actions which is often achieved by triggering actions via time stamps; for this purpose, systems need to be time-wise synchronized to a certain extent or accuracy. The Geospatial/Geodetic Engineering (GGE) Knowledge Area provides a broad introduction into this overall topic in order to make the reader aware where relevant technologies are actually used in systemssystems. It reflects the abundant uses and applications and even critical dependencies of geodetic and geospatial technologies in systems, such as GNSS & GPS (satellite positioning systemssatellite positioning systems); GISGIS; spatial reference systemsspatial reference systems; processing, analysis and visualization (portrayalportrayal) of geographic data. It briefly analyzes to what extent the Systems EngineeringSystems Engineering Specialty ActivitiesSpecialty Activities listed in the INCOSE Systems Engineering Handbook (2015) and modeling and simulationsimulation may be supported by related subject matter expertise. As a consequence it concludes that GGE activities could be considered as dedicated Specialty EngineeringSpecialty Engineering activities themselves within Systems EngineeringSystems Engineering.
