Abstract
In these days, we have lots of LiDAR (Light Detection And Ranging) data, for applications of high-resolution maps, geodesy, geomatics, archaeology, geography, geology, geomorphology, seismology, forestry, atmospheric physics, airborne laser swath mapping, laser altimetry, and others. One of current research and industrial issues is efficient ways of storing the LiDAR data itself, and also elegant ways of extracting geometric primitives from 3D point clouds of LiDAR data. In this paper, we analyze the characteristics of LiDAR data and tis storage schemes. Based on them, we present our own way of combining the existing general purpose solutions to achieve our special purpose implementation. We achieved reasonable solutions in a very short period and with very limited budgets.
