Unternehmen des Monats Dezember 2023

The project aims to digitise the existing historical archive of the Geographical Service of the Hellenic Army in order to create an open database of georeferenced aerial photographs and high-resolution orthophotos. GEOSYSTEMS HELLAS is responsible for the supply, maintenance and operation of two Leica DSW700 photogrammetric scanners for the scanning and radiometric correction of 290,000 aerial photographs in the form of negative film rolls - black and white or colour - with a resolution of 2000 dpi. In addition, it provides the supply, maintenance and operation of 20 ERDAS Imagine Photogrammetry systems, as exclusive reseller in Greece and Cyprus of Hexagon Safety, Infrastructure & Geospatial software solutions, for the purpose of aerial triangulation of scanned material for the production of orthophotomaps from 380,000 scanned aerial photographs and other relevant data. 

GEOSYSTEMS HELLAS has successfully completed the surveying of the topographic background using LiDAR system along with aerial photography, for the needs of performing flood protection works in areas of the Central Greece Motorway (E-65), which has been undertaken by "Koinopraxia Motorway of Central Greece E-65".

GEOSYSTEMS HELLAS has successfully completed the services "Development of an Information System for the Documentation and Analysis of Geospatial Data" and "Mapping of the Evolution of the Evros River Delta over Time using Satellite Imagery" for the Management Authority of the Protected Areas of the Evros and Samothrace Delta. In particular, in the first part of the contract, the installation and configuration of the geospatial data processing and mapping software on desktop computers and tablets was carried out. At the same time, the employees of the Agency were trained in the above software and a user manual was delivered. In the second part of the contract, maps of changes for the time frame 2000 to 2020 were created using free and commercial satellite data. Finally, the staff of the Entity was trained to identify changes over time using these maps.

GEOSYSTEMS HELLAS undertook the upgrade of the existing Hexagon Geospatial software of the Payment and Control Agency for Community Aid for Guidance and Guarantee - OPEKEPE as well as the supply of new software. 

GEOSYSTEMS HELLAS together with EMTEC Space P.C., ISD S.A., HERON Engineering, LEO Photonics, AUTH, EKPA and the School of Naval Cadets, will create the first twin Greek CubeSat Earth observation mission in the framework of the "HELLENIC SPACE DAWN" project - ongoing. The project partners will design, build, test, and then orbit and operate the two Hellenic Space Dawn cubesats (named Selene and Helios).

Selene and Helios, carrying remote Earth observation receivers, will have a frequency of 5 times a day and at least once a night.

GEOSYSTEMS HELLAS is responsible for the ground control and processing station (Payload Data Ground Segment) as well as for the processing algorithms and AI services for specific remote sensing applications (rapid mapping, change detection, etc.). The Hellenic Space Dawn ground station will have two distinct subsystems: a) the acquisition and pre-processing subsystem, and b) the remote sensing applications subsystem. The former is responsible for the acquisition, processing and sharing of data for public use, and the latter performs processing for specific remote sensing applications both systematically and on demand. Some of these applications involve emergency mapping and will have the ability to give cubesats download scheduling commands over specific areas for as long as needed.

GEOSYSTEMS HELLAS, together with LuxSpace and UniLu-SnT, will create an innovative solution for the detection of undetected vessels from AIS systems, meeting the requirements of maritime operators, designed with a user-centric focus on scalability and adaptability- ongoing. By integrating data from multiple sources, satellite data (EO), AIS data, and radio frequency (RF) data, along with machine learning technologies, MAGINet enhances maritime situational awareness, improves vessel detection accuracy, and supports proactive decision making.

GEOSYSTEMS HELLAS within the MAGINet project has undertaken the collection of Earth Observation (EO) data, providing the fundamental data for the development of the system. GSH is leading the development of vessel detection methodologies, utilizing advanced Machine Learning technologies. In addition, GSH has a key role in the technical aspects of the project, including the implementation and integration of satellite image processing algorithms (optical & radar) into the GSIN Demonstrator. Their responsibilities further extend to providing technical support for the formulation and execution of the performance test and development plan, highlighting their role in ensuring the success of the project.

The TRIQUETRA project aims to create a Decision Support System (DSS) that allows the assessment and reduction of risks to monuments and heritage sites and integrates a data base (Knowledge Base Platform) with available measures and mitigation strategies, which will be created by GEOSYSTEMS HELLAS-ongoing

The data collection within the project provides a comprehensive picture of all parameters directly or indirectly related to Climate Change, comparing them with corresponding historical data. Furthermore, new innovative recording and documentation methods will be used.

The DSS and the technologies developed in the project will be tested in real-life conditions at 8 pilot sites in 6 different European countries, including the archaeological site of Kalapodiou in Fthiotida, which was discovered in the excavations started in 1974 by the German Archaeological Institute (DAI), which is participating in the project as a partner invited by our company.
