High-Resolution Mapping with Unmanned Aerial Systems
The fusion and miniaturization of spatial technologies such as GPS and the emergence of affordable platforms to carry these technologies has opened up new opportunities for high-resolution mapping. In this paper we discuss the results of pilot tests carried out in Albania at the end of 2013 through an Innovation Grant from the Europe and Central Asia (ECA) division of the World Bank. Our objective was to design and test a methodology based on an unmanned aerial system (UAS) for producing high-resolution orthophotos that could be used for urban planning, infrastructure routing, and environmental monitoring and as a basis for improving existing cadastral data. We outline the methodology in terms of: (a) prefield preparation and mobilization; (b) field work (including premarking, geodetic and ground control, and flying); (c) postfield processing (Multiview Stereopsis, production of orthophotos and 3D models, quality control and assessment).
