ANTONIOS FEKAS
I'm a graduate of the School of Spatial Planning and Development, of the Faculty of Engineering, of Aristotle University of Thessaloniki. I hold a Master's Degree in Spatial Planning and Regional Development.
My decision to chose Engineering as a professional career, was highly influenced by my father who himself was a Surveying Engineer. After the completion of my studies, I teamed up with several companies which specialized in the Cadastre Sector. Through these experiences I managed to upgrade my skills in the process of land registration, Photogrammetry and land surveying with GNSS technology and unmanned aircraft systems (UAV).
I joined the family of Consortis in 2020. The company gave me the chance to extensively work on the Geospatial and GIS sector.
Sessions
The presentation will discuss Q-MOKA, a GIS application developed in collaboration with the Hellenic Ministry of Infrastructure and Transportation to manage and analyze traffic accidents along the Greek Primary and Transeuropean Road Network. Q-MOKA addresses the challenges of the existing Traffic Accident Registry, which lacked geospatial referencing and robust data validation. Built around QGIS and Postgres/PostGIS, Q-MOKA offers several key functionalities:
• Network Model: Supports multiple linear referencing systems for accurate accident location representation.
• Dual-Carriageway Management: Ensures consistent linear referencing even during network realignments.
• Flexible Accident Location: Records accidents by X,Y coordinates or route/offset, maintaining synchronization between the two methods.
• Linear and Point Data Management: Allows creation and editing of additional linear and point event data relevant to the Agency (e.g., number of lanes, speed limits).
• Geographic Mapping: Provides route-level accident mapping based on the recording service.
• Custom QGIS Forms: Facilitates data entry and management through user-friendly forms.
The presentation will delve into the technical aspects of Q-MOKA, including its database structure, configuration options, and potential future enhancements. By offering a robust and user-friendly platform for traffic accident management and analysis, Q-MOKA contributes to improved road safety and informed decision-making in Greece.
