Trees

The «Trees» plate shows the tree crowns around the site: in Berlin and Cologne from the tree registers, in Stuttgart and Karlsruhe estimated from the surface model.

Overview

The «Green space and water» plate shows areas: it shows land use, not where the trees stand. It does not separate lawn from tree cover in a park and contains no street trees. The «Trees» plate shows the crowns themselves. The source differs by city.

Display

Crowns that touch merge. Crowns inside buildings or over water are removed. Where the crowns are dense, the plate draws continuous canopy as an area, otherwise individual circles. In the legend the circle is called «Individual trees» and the area «Continuous canopy». The circles are not a tree count.

Thermal comfort

Tree shade in the thermal comfort map uses the same crown mask.

Limitations

• Recorded trees only (Berlin, Cologne). The Cologne tree register contains only public trees; trees in private gardens and courtyards are missing. A courtyard full of trees can appear empty
• Estimate from the surface model (Stuttgart, Karlsruhe). nDOM1 contains everything that rises above the terrain. Walls, roofs and masts from 3 m upwards can appear as crowns
• Crown size. Where the register gives no crown, it is estimated. The real crown can be larger or smaller
• Date. Later felling and planting are not included
