GPS Monitoring and GIS-Based Spatial and Temporal Analysis of Land Subsidence

Abstract

Abstract: As an example, the method of land subsidence monitoring by GPS was introduced in Jiangyin area, Jiangsu Province, China. The result stated that the precision of GPS data was able to satisfy the requirement of land subsidence monitoring. The authors discussed how to analyse the spatial and temporal law of subsidence based on GIS according to the GPS monitoring data. The GIS-based spatial and temporal analysis system for GPS data provided an advantaged method to analyze the law and correlation with the groundwater exploitation of the land subsidence.

Key words: GPS, land subsidence, spatial and temporal law, GIS
