CyGOS Operational Services
CyGMS — Cyprus Ground Motion Service
Cyprus's national, operational service for monitoring how the ground is moving — continuously, precisely and across the whole island. CyGMS turns satellite and ground-based observations into ground-displacement and velocity products that authorities, infrastructure operators and researchers can act on.
CyGMS (Cyprus Ground Motion Service) is Cyprus's national, operational ground motion monitoring service. It transforms continuous GNSS (Global Navigation Satellite Systems) and satellite InSAR (Interferometric Synthetic Aperture Radar) observations into ground-displacement and velocity products for the whole of Cyprus, delivered through a dedicated, fully operational WebGIS platform. It is the national counterpart and complement to the European Ground Motion Service (EGMS), calibrated and validated specifically for Cyprus's deforming tectonic setting — a national service, not a pilot or future capability.
CyGMS was developed and rendered operational as a deliverable of the CyCLOPS+ project, implemented by a consortium coordinated by the Cyprus University of Technology (CUT), together with the ERATOSTHENES Centre of Excellence (ECoE), the German Aerospace Center (DLR) and GEOGRAFICA Ltd. Its continued development and operation are now integrated into CyGOS, Cyprus's national geohazard observatory.
What CyGMS delivers
National GNSS velocity model
A velocity model for Cyprus in the global IGS20/ITRF2020 and European ETRF2020 reference frames, providing the geodetic reference that anchors the radar products.
InSAR ground motion products
Products from Sentinel-1 (ascending and descending), combining Persistent Scatterer Interferometry (PSI) at national scale with Small Baseline Subset (SBAS) in areas of complex deformation such as active landslides.
Interactive WebGIS platform
Visualise, query and explore the products across desktop, tablet and mobile, with authenticated, role-based access at cygms.cut.ac.cy.
A three-level product structure, aligned with EGMS
CyGMS products follow the same three-level structure as the European Ground Motion Service, so they can be used alongside continental data:
Basic
Line-of-sight displacement and velocity, measured along the satellite's viewing direction.
Calibrated
Referenced to the national GNSS velocity model for consistency and accuracy across Cyprus.
Ortho
Vertical and east–west motion components resolved on a regular grid.
Why CyGMS for Cyprus
CyGMS is built on the CyCLOPS national research infrastructure — the largest scientific GNSS network in Cyprus — and is designed for the island's active tectonic setting.
Calibrated for Cyprus
EGMS calibrates satellite measurements with a continental-scale GNSS model; CyGMS adds Cyprus's dense national GNSS network for higher spatial resolution and accuracy at the national level.
Resolving fast ground motion
EGMS provides consistent, pan-European coverage. CyGMS complements it for Cyprus by combining PSI with SBAS, adding the ability to capture fast-moving phenomena such as the Pissouri landslide.
From observation to service
CyGMS does not stop at research. It is an operational national service, turning continuous observations into ground-motion products that authorities and professionals can act on.
Who benefits
CyGMS supports evidence-based decision-making across the public and private sectors.
Government & competent authorities
Geohazard monitoring, hazard assessment and emergency management, backed by reliable national-scale deformation data.
Local authorities & communities
Support for land-use planning and local decisions, with a clear picture of how the ground is moving in their area.
Infrastructure operators & asset managers
Reliable deformation information for roads, bridges, dams and networks — for condition assessment, resilience and planning.
Researchers & the scientific community
An open, calibrated, national-scale dataset spanning slow tectonic motion to active landslides.
Access the service
CyGMS products are delivered through the operational WebGIS platform under registered, role-based access, consistent with the CyGOS commitment to open science and the GSNL Supersite Data Policy Principles.
CyGMS platform
cygms.cut.ac.cy — visualise, query and explore ground-motion products for the whole of Cyprus.
Register for access
Access is granted after registration through a secure authorisation layer. To request access to the CyGMS and CyCLOPS data services, contact the Coordinator.
Part of CyGOS
CyGMS is the first operational service of CyGOS (Cyprus Geohazard Observatory Supersite), Cyprus's internationally recognised geohazard observatory and a Permanent Supersite of the GEO Geohazard Supersites and Natural Laboratories (GEO-GSNL) initiative. CyGOS is coordinated by the Laboratory of Geodesy at the Cyprus University of Technology.
National research infrastructure — the observing backbone of GNSS stations, radar reflectors and sensors.
Internationally recognised observatory and GEO-GSNL Permanent Supersite that integrates the observations.
Operational ground motion service delivering products to authorities, industry and researchers.

CyGMS was initially developed and deployed under the CyCLOPS+ project (Cyprus Ground Motion Service, SMALL SCALE INFRASTRUCTURES/1222/0082), implemented under the THALIA 2021–2027 programme of the Research and Innovation Foundation (RIF), co-funded by the European Union.
