APPARATUS AND METHOD FOR PREPARING MAP OF GREEN COVERING RATIO, AND PROGRAM

PROBLEM TO BE SOLVED: To provide a map of a green covering ratio with high resolution, and also to provide an apparatus, etc. for preparing a green zone map. SOLUTION: The apparatus for preparing a map of a high-resolution green covering ratio uses image data obtained by photographing the reflected light intensity of a certain wavelength band by one band sensor. In addition, a panchromatic image data which are image data obtained by photographing the reflected light intensity of a certain wavelength band while dividing the wavelength area by a plurality of band sensors are also used. The apparatus for preparing a map of a high-resolution green covering ratio can prepare a map of green covering ratio having higher resolution as compared with a conventional map by using the luminance value of the panchromatic image data and the infrared band value of resampled multispectral image data. When the apparatus for preparing a map of a high-resolution green covering ratio is applied to aerial photographs and satellite images, a map of a high-resolution green covering ratio over a wide area can be easily acquired.
