Abstract
The GIS system works based on the principle that after GPS satellite signals are used for positioning, the geographic position of a monitoring point is obtained through analysis and calculation by combining a digital map, and therefore various commercial and public service applications are achieved. Because of the limitation of GPS signal precision, the interference of various building materials on positioning signals and the technical problem that no unified digital map exists in indoor geographic space at present, a GIS system supporting indoor application is lacking at present. The invention provides an indoor space information management system, which depends on WLAN (wireless local area network) to carry out indoor positioning, combines mapping to generate an indoor space map, and uses a space database to store indoor geographic space data information, thereby realizing commercial application of the indoor space geographic information system and effectively filling the market blank.
