Basic characteristics of component GIS

If the functions of GIS are properly abstracted and used by developers in the form of components, it will bring many incomparable advantages to traditional GIS tools. Abstraction of specific algorithms for industrial applications is solidified into components, which further speeds up the development process. Take GPS monitoring as an example. For GPS applications, in addition to general GIS functions such as map display and information query, specific application functions are also needed, such as dynamic target display, target locking and trajectory display. After these GPS industrial application functional components are encapsulated, the developer's work can be simplified as setting the legend of the display target, the color of the track display, the locked target, and the method of calling and receiving data.
