Half-dense roof greenery map

Quick answer：

A half-dense roof greenery map is a visual representation that illustrates a type of green roof design featuring a moderate density of vegetation. Green roofs are designed to provide various environmental benefits such as reducing urban heat island effect, improving air quality, and providing additional insulation for buildings. In a half-dense roof, the vegetation coverage is not as thick as in a full-dense roof but still allows for some soil depth to support plant growth.
