A Study on the Technical Problem of How to Grasp Greenery Occupancy in an Urban Area

Abstract

The purpose of this study is to compare three methods to grasp greenery occupancy in an urban area, that is, decipherment of color airial-photo, image processing of color IR airial-photo and image processing of LANDSAT data.
The following results are obtained,
(1) Dicipherment of color airial-photo is read accurately and has a tendency to induce a difference on the stage of extraction, mapping and totalizing.
(2) Image processing of color IR airial-photo is able perform good extraction, mapping and totalizing in spite of the necessity of partial modifications because of its digital processing.
(3) LANDSAT data is suitable for the global grasp of greenery occupancy.
