Joint Workshop in Jakarta with Synspective Inc. and PT. MRT Jakarta on Small SAR-Based Ground Deformation Monitoring
On February 5, 2026, Oriental Consultants Global Co., Ltd. (OC Global; Headquarters: Shinjuku-ku, Tokyo held a workshop in Jakarta, the Republic of Indonesia, to present the results of a ground deformation monitoring platform utilizing small SAR satellite data. The workshop was conducted as part of the Ministry of Land, Infrastructure, Transport and Tourism of Japan’s “Smart JAMP Study for the Realization of Smart Cities.”
At this workshop, OC Global signed the “Collaborative Minutes on Strategic Cooperation” with PT MRT Jakarta (hereinafter “PT. MRTJ”), the operator of the Jakarta Mass Rapid Transit (MRT) system, with the aim of promoting the social implementation of this solution and its application to future railway construction projects.

OC Global has long supported the development of railway networks and transit-oriented development (TOD) initiatives in the Jakarta metropolitan area. In recent years, land subsidence has become a serious urban issue in Jakarta, raising concerns about its impact on existing infrastructure as well as railway lines currently under construction. In response, OC Global has collaborated with Synspective Inc. (Headquarters: Koto-ku, Tokyo) to promote the overseas expansion of millimeter-level ground deformation analysis using SAR (Synthetic Aperture Radar) satellites and an integrated GIS (Geographic Information System) platform that centrally manages such data. This project aims to apply these advanced technologies to actual infrastructure construction supervision in order to support safe and efficient urban development.
The workshop was attended by approximately 50 participants, including PT. MRTJ, the Indonesia’s Geospatial Information Agency (BIG), the National Agency for Disaster Countermeasure (BNPB), local construction companies, the Embassy of Japan in Indonesia, and Japan International Cooperation Agency (JICA). As part of the demonstration results for the MRT North–South Line (Harmoni–Mangga Besar section), it was reported that the SAR satellite analysis data showed an extremely high level of consistency with on-site surveying data. Furthermore, by capturing broad land subsidence trends on an area-wide basis, the system demonstrated its capability to enable wide-ranging risk management that would be difficult to achieve using conventional ground-based sensors alone. During the demonstration of the “Construction Supervision Platform” developed by OC Global, explanations were provided on functions that integrate and display, on both 2D and 3D maps, the real-time positional information of tunnel boring machines excavating underground tunnels and ground displacement data, as well as features allowing comparison between satellite-derived analysis data and on-site survey results. The platform received high praise from participants as a next-generation infrastructure management tool.
Based on the Collaborative Minutes signed on this occasion, OC Global and PT. MRTJ will pursue the full-scale implementation of this system as a construction supervision tool for railway infrastructure projects. In addition, they will develop a land risk information provision service for surrounding developers, including PoC and a pilot implementation model. Through these initiatives, the parties aim to support safe and efficient urban development in Indonesia and across ASEAN, thereby contributing to the realization of smart cities in the region.
OC Global will go beyond the conventional role of a “construction consultant” and, as a high value-added solution provider leveraging satellite data and DX (Digital Transformation) technologies, continue to contribute to sustainable urban development and economic growth in emerging countries.
