土地測量 - 面積・距離の測量・計算・計測

Why this icon holds up

On 2026-08-13 the vault captured the 土地測量 - 面積・距離の測量・計算・計測 icon (Navigation, BR): 蓝色背景，中间是一张绿色的折叠地图，上面有一个紫色的多边形和白色的点，右下角有一把绿色的尺子。

Small-size readability

• Contrast: green mark on blue fill — check both dim OLED and bright LCD.
• Silhouette budget: map, ruler, polygon, dots should remain readable after the store’s rounded-square crop.
• illustration/photo detail collapses quickly below ~60px — verify the 60px mental model before trusting the master.
• Internal usability score for this capture: 0.6/100 (heuristic, not a store ranking).

These checks are practical references for designers reviewing 土地測量 - 面積・距離の測量・計算・計測, not authoritative store scores.

Transferable design moves

• Keep map as the primary silhouette before adding secondary ornaments.
• Concentrate the loudest chroma on the identifying shape (green), not the whole blue field.
• This capture’s illustration/photo vocabulary transfers best when the same restraint is applied at export size.
