Geofem has coordinated and participated in many publicly-funded research programmes in the fields of satellite remote sensing for ground and infrastructure movement applications, atmospheric pollution monitoring, water quality assessment, water leakage detection, land use, cultural heritage and natural hazards.
The research projects have included earth observation applications including optical, thermal and other satellite data for a wide range of applications such as:
Water Quality Characteristics
A system for the automated determination of water turbidity was developed at Geofem where values of turbidity can be extracted at study areas during each satellite pass. This is applicable to dams, lakes and sea. Such an analysis was performed at the Evretou, Aspokremos and Kourris dams in Cyprus.
GEOFEM was a core partner in the EU funded ANDROID project aimed at increasing society's resilience to disasters of human and natural origin. It was based on an inter-disciplinary consortium of partners that comprised scientists from applied, human, social and natural disciplines. ANDROID set out to achieve this aim through a series of inter-linked projects and led by a sub-group of international partners.
We apply satellite remote sensing data processing and earth observation to determine crop irrigation demand based on crop characteristics to optimise crop cultivation. Crop specific algorithms are developed to enable automated crop irrigation demand estimation based on growth stage and crop characteristics, specific for the study area.
‘Risk Evaluation Tool for Assessing the Risk of Uplift and Subsidence from Swelling Clays using Radar and Geotechnical Data (RET-UPS)
This is a project funded by the European Space Agency under the 2nd PECS – Cyprus Call. It is commenced in May 2019 and will run for two years.
Swelling clays experience large volume variations as moisture levels change due to seasonal changes. These cause subsidence and heave and hence damage to buildings and infrastructure. This geohazard is widely referred to as swelling-shrinking clays. Even though the hazard of swelling-shrinking clays has not received much attention compared to other natural hazards, the cost from the damages outweighs those caused by floods, landslides and earthquakes combined. It is therefore vital to derive a means for the detection, estimation and prediction of ground movement caused by expansive clays. The project aims to develop a Risk Evaluation Tool in a GIS environment which will enable the categorization of areas covered by swelling clays into different risk levels using a synergy of SAR technology with geotechnical, geological and soil moisture data. For this purpose, InSAR technologies (using Sentinel-1 SLC data), optical data (Sentinel-2) and SAR data (Sentinel-1 GRD) will be used together with in situ data for deriving soil moisture estimations, geotechnical and geological soil characteristics.
