摘要

The volunteered geographic information was introduced in 2007 and was first applied in navigation and mapping purposes. Currently, it has been applied in various fields and has been used for various purposes. The paper focuses on the potential of integrating crowdsourcing techniques in the compilation procedure of cadastral maps. This research aims to investigate the intention of citizens over the specific perspective in a theoretical approach and to analyze the results of the first experiment carried out in Greece. The main aim of the research investigates on citizens' intentions, motivations' analysis and in depth evaluation of the current official cadastral process. The research examined a wide range of participants of various ages and educational background composing an unbiased sample in Greece. A questionnaire was compiled and distributed to more than 250 volunteers. The volunteers were mainly questioned about their intention to participate in cadastral mapping and the potential motivations behind their participation. The research was carried out by filling out anonymous questionnaires in an online platform, adopting the exponential non-discriminative snowball sampling methodology. The research first focused on (a) raising awareness and exploring volunteers' availability and their familiarity with the new technologies; (b) identifying the reasons which would lead them to participate in cadastral mapping; and (c) volunteers' opinions about the efficiency of the official traditional cadastral surveying procedure.
