Vegetation Structure of the Green Volume 2009 (WMS Service)

Description

The present vegetation structure of the green volume is based on an interim result from the expert report “Green Volume Determination of the City of Dresden on the basis of laser scan data” prepared by the Leibniz Institute for Ecological Spatial Development (IÖR) of August 2014. This can be viewed under the assigned document. Introduction: Urban green is indispensable from an urban ecological and social point of view and fulfils important functions such as dust retention, temperature reduction, wind damping or groundwater regeneration. In addition, public green spaces provide oasis of tranquility, which serve recreation, leisure and communication and fulfil important social functions. The ecological effectiveness of the urban green depends in particular on the present vegetarian structure. For example, low vegetation (lawns and meadows) has a cooling effect, especially in the evening and night hours, while high vegetation (medium to large trees) mainly contributes to a reduction in climatic stress during the day, but at the same time can negatively affect ventilation. Medium vegetation (shrubs, perennials, hedges and small trees) as well as the high vegetation has a high degree of dust binding from the air, while low vegetation mainly binds dust and gas parts from precipitation and contributes a large proportion to groundwater regeneration due to the high leakage capacity (see also metadata for the planning information map Urban Climate). Background: For the green volume determination it was imperative to separate vegetation from anthropogenic objects with a relevant height above the ground, such as buildings, lanterns, vehicles, etc. At the same time, the application of the crown shape correction (only on deciduous trees) and the flat-rate surcharge for lawns and arable land required further differentiation according to vegetation types. The following types of vegetation should be separated from each other: — Deciduous tree — Conifer — Shrubs — Lawn — Field. Data base/methodology: The basis for determining the vegetation structure (as an interim result of the green volume determination) is laser scan data, RGBI image data and building data. Classification of the vegetation structure of the green volume: — Value 0: vegetationless => (colorless or white) — Value 1: Deciduous tree => (green) — Value 2: Conifer => (dark green) — Value 3: Shrubs => (brown green) — Value 4: Lawns, meadows and other low vegetation => (yellow green/light green) Value 5: Field => (yellow green/light green)
