670 ITU‐T's Technical Reports and Specifications Figure 15 – Application scope of technical specification for resource and toponym database matching in the integrated management for smart sustainable cities 3.3.1.3 Content The fusion of nodes and the toponym database, assigning the actual place name information to nodes, will make it convenient to overlay nodes on maps or images, and increase the efficiency of sensor accessing and dispatching. Fusing sensors with the toponym database will facilitate the graphical display of sensors on the map, and provide data support for sensor planning, arrangements, as well as intensive observations under emergencies. The observations fusing with the toponym database, mainly adding observed properties, will make the demonstration of the data's geographic positions more intuitive, and convenient to be invoked at any time. The fusion between events and toponym, adding graphic position labels for events, will contribute to map display, pattern of spatial distribution, and causality inferring for events. The technical workflow of matching resources up with the toponym database in IMSSC is shown in Figure 16 [b‐Smart].
