• Airborne laser profiling of mainland Ehime Prefecture, Japan was conducted to develop an entirely new method of land-cover classification, partly in preparation for the post-Kyoto national carbon budget accounting, and partly for correction of the existing government land-use statistics, which should constitute the very basis of the impending national carbon budget accounting of the Kyoto Protocol. The altimetry data was obtained by using NASA's Portable Airborne Laser System (PALS) along 23 parallel flight lines 4km apart from each other covering the whole mainland portion of the prefecture. Based on the resulting surface profile representing topography and structures on the ground with some reference to laser return intensity and nadir video images, land cover along the flight line was classified into "forest", "farmland", "residential and urban", and "others" using PALSA (PALS Analyzer), a software developed for this particular purpose. This line evaluation was then developed into area statistics by simply multiplying by the distance between the flight lines, i.e. 4km. The resultant land-cover estimates not only differed from the existing government statistics as much as the latter does within itself, but also helped to identify the causes and sources of discrepancy quantitatively. Thus it was concluded that coordinated use of this new method with the existing system of land-use statistics would improve the overall credibility of the land-use/land-cover statistics of the prefecture and the nation.
