Abstract
The real-time mapping system combines information and communication technology (ICT), mapping techniques, and GIS spatial analysis. The system's architecture includes a sensor and infrastructure layer, a functional and service layer, and an application and presentation layer before delivery to users. The development of ICT and GIS has created the basis for the formation and development of a modern cartography product: Real-time maps that provide timely and fast information and data associated with the space-time of objects, phenomena, natural processes, environment, and society to users visually and vividly. This article introduces the basic technology infrastructure developed and applied to real-time mapping and the WebGIS real-time noise map system successfully developed by the Vietnam Institute of Geodesy and Cartography in 2021
