Building state monitoring system based on GIS

The invention provides a GIS-based building state monitoring system. The GIS-based building state monitoring system comprises a data acquisition unit, a DTU module and a remote monitoring platform deployed at a remote server side, the data acquisition unit is used for acquiring deformation data of a building and sending the deformation data to the DTU module; the DTU module is used for receiving the deformation data and uploading the deformation data to the remote monitoring platform; the remote monitoring platform is used for constructing a GIS monitoring map based on a monitoring map construction instruction input by a user; position coordinates of a building area, position coordinates of the data acquisition module and position coordinates of the DTU module are marked on the GIS monitoring map; the remote monitoring platform is also used for generating a monitoring report based on the received monitoring data of each building, storing the monitoring report in a background database, and associating a storag
