A technical solution for 3D crowdsourced cadastral surveys

摘要: Abstract The development of 3D property registration systems is indispensable for the spatial determination Rights, Restrictions and Responsibilities (RRR), sustainable operation markets safeguarding ownership in highly urbanized world. Several developments computer graphics, modelling rendering techniques have attracted growing global interest cadastre. Since 2012, Land Administration Domain Model (LADM ISO 19152) adopted as international standard 2D cadastral data modelling. Developed legal procedures prototype rights provide interesting solutions acquisition visualization but such approaches are time cost demanding. In parallel, surveying progressed significantly reducing required cost, utilizing crowdsourcing methodology mobile services. This paper presents a technical solution under development, aiming to beginning new era initial acquisition, representation crowdsourced data, appropriate both developed developing proposed consists two complementary parts, framework be followed. interconnected server-side client-side. refers Database Management System (DBMS) where collected stored. client-side capturing tool, which this case device. For server-side, system based on model driven architecture practices LADM developed; while client-side, an open-source application units block models (LoD1) mobile’s phone screen real-time, developed. research focused investigating aspects integrating about physical objects. Detailed investigation issues not within objectives research. Two case-studies testing made. An assessment current stage presented. main conclusions converge that has huge potentials fast, economic implementation surveys it can produce accurate reliable information model, depending accuracy available basemaps. easy-to-use users may necessary level skills order contribute procedure.
