466各種土地被覆情報との分析による都市地表面アルベドの特性に関する研究

Abstract

The urban surface albedo was estimated using four methods; 1) Panchromatic, 2) NVI (Normalized Vegetation Index), 3) Land cover ratio calculated by the constrained least square method, 4) Detail mesh data on land uses. The methods 1) -3) were derived from Landsat TM data. The histgram s of the estimated albedo were compared with each others. The result estimated by the panchromatic method was best. The result estimated by Detail mesh data on land uses had a problem based on the discrete values.
