Who operates it
- InaCORS (Indonesian Continuously Operating Reference Stations) is operated by the Geospatial Information Agency of Indonesia (BIG — Badan Informasi Geospasial).
- It is the official national CORS network, forming part of the country’s geodetic reference system.
Availability & access
- InaCORS data and services are generally available free of charge through the BIG portal.
- Provides real-time corrections via NTRIP and RINEX data for post-processing.
Coverage & scale
- Nationwide coverage with hundreds of reference stations distributed across Indonesia’s vast archipelago.
- Integrated into regional geodetic networks in Asia-Pacific and aligned with the International Terrestrial Reference Frame (ITRF).
Typical use cases
- Land surveying and cadastral mapping.
- Infrastructure development, including ports, bridges, and transportation networks.
- Disaster management, including monitoring earthquakes, tsunamis, and volcanic activity.
- Scientific research in geodynamics, climate change, and sea-level rise.
How it’s used in practice
- Surveyors connect GNSS equipment via NTRIP to InaCORS for real-time RTK corrections.
- Researchers download RINEX data for static and kinematic post-processing.
Notes
- Indonesia’s position on the Pacific “Ring of Fire” makes InaCORS crucial for tectonic monitoring and disaster preparedness.
- It is also vital for modernizing the nation’s cadastral and geospatial infrastructure.
