| Popis: | Volunteered Geographic Information (VGI) has been used in various scientific domains and applications. Surveying Engineering is a field that has not yet exploited concepts like data and service sharing and reuse. This paper aims to suggest a framework that will support data sharing in Surveying Engineering by creating an online spatio-temporal information repository for land surveying projects. A data model to meet the needs for Surveying Engineering applications and accuracy requirements is introduced to facilitate the sharing of VGI information among Surveying Engineers. A fully functional prototype system has been developed and used to apply the proposed methodology in a large scale study undertaken by the Greek Ministry of Culture which involves the mapping of the historic center of Athens as part of the Archaeological Cadastre project. Results coming from data analysis indicate a substantial (~60 %) error reduction and also significant productivity raise (~25 %), while at the same time, the collected data are structured and saved in an online database, accessible by community users—professional Surveying Engineers who can in turn contribute to further improve the available data and services according to the principles of VGI applications. |
