Creating highly informative rasters based on laser scanning and aerial photography data

Abstract

The paper is focused on scenario and terrain modeling using the results of aerial laser scanning combined with digital aerial photography. The advantages and disadvantages of these technologies are discussed in regard to the construction of large-scale topographic maps. The generalized sequence of cameral processing aerial survey data is investigated. Based on our research, we believe that developing a combined technique of presenting Lidar survey and aerial photography materials is feasible; it could simplify and speed up the operator`s (cartographer`s) work. The novelty of the research is the formation of algorithms for creating original raster images containing more information on the terrain in each section than the orthophotoplane familiar to the interested user. The criteria for the object composition of materials are worked out taking into account the specifics of the methods under consideration, variants of information combinations are formulated for broader opportunities of analyzing and interpreting the data on the territory. Various approaches to the implementation of these ideas are shown. Examples of testing developments are given.
