Abstract

Borneo Island is home to the world’s largest peatland with relatively straightforward tectonics movement. Those nature would be beneficial to illuminate the hydrological cycle of the Earth-surface processes. We analyzed the total water storage changes deduced from the Gravity Recovery and Climate Experiment (GRACE) satellite where the Global Navigation Satellite System (GNSS) network may detect its deformation. High-frequency data in GNSS observation might benefit the hydrological cycle real-time monitoring. We investigate the spatial correlation of GRACE-based total water storage changes and the GNSS-derived horizontal dilatational strain rate. We found that the dilatational strain rate based on GNSS data negatively correlates to the Equivalent Water Height (EWH) change observed from GRACE data. Hence, the extensional dilatation rate (> 20 nanostrain/yr) is observed exactly in the decreased EWH region ( <-13 mm), while the compressional dilatational region (< -20 nanostrain/yr) is observed in the increased EWH (> 20 mm) trend. Finally, we highlighted that GNSS observation’s precise horizontal dilatation rate in Borneo Island is reliable for detecting seasonal total water storage changes.

期刊介绍： Applied Geomatics (AGMJ) is the official journal of SIFET the Italian Society of Photogrammetry and Topography and covers all aspects and information on scientific and technical advances in the geomatics sciences. The Journal publishes innovative contributions in geomatics applications ranging from the integration of instruments, methodologies and technologies and their use in the environmental sciences, engineering and other natural sciences. The areas of interest include many research fields such as: remote sensing, close range and videometric photogrammetry, image analysis, digital mapping, land and geographic information systems, geographic information science, integrated geodesy, spatial data analysis, heritage recording; network adjustment and numerical processes. Furthermore, Applied Geomatics is open to articles from all areas of deformation measurements and analysis, structural engineering, mechanical engineering and all trends in earth and planetary survey science and space technology. The Journal also contains notices of conferences and international workshops, industry news, and information on new products. It provides a useful forum for professional and academic scientists involved in geomatics science and technology.
