JENGO, a prototype mobile application based on crowd sourcing for LIS
Abstract
The possibility of collecting data with one's own mobile tools is very inviting and at the same time attractive, and useful. There are strong initiatives to adopt crowdsourcing, citizens in Land Administration. In that way citizens can be provided with useful and easy-handling mobile tools for mapping, so they can give land related information with their own mobile phone (McLaren, 2011; Brabham, 2013). On the one hand in many less developed countries the people lack land rights documents and citizens without documentation often lack secure tenure over land. On the other hand the inadequate quality of cadastral maps affects the life of citizens who need means to quickly and cost-effectively settle their cadastre related issues. The first goal of paper is to identify the success factors relevant to cadastre related crowdsourcing projects. Another goal of paper is to present an adequate mobile application, according to the established factors, Jengo, for mapping 2D/3D buildings/constructions and to record attributes, including photos, and also for uploading captured data to the system of those who are asked to participate in the crowdsourcing campaign. The methodology of collection includes primary objectives which were the on-site scanning of a construction, identification and recording of their violations and graphical presentation of their expansion on the OS map.
