A207 航空レーザ計測でみる都市の姿

抄録

The aerial laser survey is the advanced technology of measurement of altitude by means of laser irradiation device installed in the aircraft. The accuracy of altitude measured by laser is ±10cm in horizontal, and ±15cm in vertical respectively. In this paper, by using aerial laser survey data, space occupation ratio was shown as an example of visualization of appearance of city. Space occupation ratio was found to be corresponding to the land use, such as residential area was high space occupation ratio and river and main roads were low. It was shown through the example that the appearance of the city can be made visible by the expression of statistical characteristics reduced by making full use of the original laser data.
