Abstract

Geographic information is increasingly contributed by volunteers via crowdsourcing platforms. However, most tools and methods require a high technical affinity of its users and a good understanding of geographic classification systems. These technological and educational barriers prevent casual users to contribute spatial data. In this chapter we present mapIT, a method to acquire and contribute complex geographic data. We further introduce the concept of micro-mapping, the acquisition of geometrically correct geometric data of small geographic entities. mapIT is a method for micro-mapping with smartphones with high geometric precision. We show that mapIT is highly accurate and able to reconstruct the geometry of mapped entities correctly.Please check and confirm the author names and initials are correct.
