Aerial View Before and After: Changes in Street Texture

A set of before-and-after aerial comparisons of the same urban block, showing changes in its texture. The first image shows dense, fragmented rooftops: various colored corrugated iron additions, water tanks, clotheslines, narrow courtyards, and intersecting alleys. The second image shows the same area after renewal: two or three large roof volumes, neat mechanical rooms and greenery, a central courtyard, and the disappearance of the original alleys. The scope, height, and angle of both images must be exactly the same, with surrounding un-renewed areas remaining unchanged for comparison. Avoid: changing the scope or angle of the two images, renewing the surrounding areas as well, omitting the surroundings for comparison, or depicting the rooftops in the first image as neat.

一組同一街廓的空拍前後對照。前一張是密集細碎的屋頂:各種顏色的鐵皮加蓋、水塔、曬衣架、狹窄的天井與穿越的巷道;後一張是相同範圍的更新後:兩三個大的屋頂量體、整齊的機房與綠化、中間的中庭,原本的巷道消失。兩張的範圍、高度與角度完全一致,周邊未更新的區域維持原狀作為對照。避免:改變兩張的範圍與角度、把周邊也一起更新、省略周邊作為對照、讓前一張的屋頂被畫得整齊。
