A Proposed Crowdsourcing Cadastral Model: Taking Advantage of Previous Experience and Innovative Techniques

Abstract

Are Land Owners able to participate in official Cadastral Surveys? Can the offi-cial procedures be modified in order for crowdsourcing techniques to be incor-porated in them? How many different stakeholders can actively get involved and which is the optimum workflow that could be adopted? This chapter addresses the main question of whether the spatial and attribute data that is collected by volunteers – land owners – can be used in official Land Adminis-tration Systems (LAS) and explores the potential introduction of crowdsourc-ing techniques into the official cadastral surveys as a simplified and transparent procedure with the aid of citizens. As the title reveals, this chapter aims to propose a crowdsourcing cadastral model as an alternative option to the official cadastral procedures. The research investigates a voluntary model and documents it in terms of participants and structure according to various international case studies that were analyzed in depth within the research that was carried out by Haklay et al. (2014). The main lessons that were collected by each separate crowdsourced case study were used as a guideline for the suggested cadastral model. The opportunities and the weaknesses are isolated and explored in terms of a cadastral survey. The main advantage of the adopted case studies is the opportunity for a simulation of
