Urban green space - Satellite maps

The BUGS project deals with urban greening in order to promote a higher quality of life regarding air pollution and noise annoyance. The overall goal of the WPGEOMAP consists of the production of satellite-based urban geographic maps containing surface parameters, and application of spatial modelling techniques to re-design the same area, focusing on the enhancement of green area accessibility and connectivity. The land use/land cover (LU/LC) files allows to locate and to quantify the different types of landscape features in urban areas. It is obviously necessary to know where, how much and with what kind of patterns LU/LC categories are distributed in the urban area.

The results will provide reliable parameters usable in other work packages in order to understand the main outlines of atmospheric circulation and pollutants transportation trends at different scales, for the whole urban area and for very local places. The influence of urban structures of characteristics on air quality is important to integrate different scales of analysis and this is one of the objectives of the BUGS project.

Several layers are necessary to be used in partner’s models: land-use/ cover categories, Normalized Difference Vegetation Index (NDVI), Land surface Brightness Temperature. Other layers are associated: connectivity layer dealing with green areas and accessibility layer dealing with access to urban green spaces in the city.

The first case study is the Urban Community of Strasbourg (Communauté Urbaine de Strasbourg- CUS); it covers approximately 300km2. In the 1999 French census the urban population reaches 480 000 inhabitants.

Several layers have been realized to observe the city and urban green spaces in order to locate, identify and analyse the different LU/LC components. From the simplest (colour composite image) to the more sophisticated (classification file) numerous image-processing methods have been used. These types of results have been achieved on two types of satellite images: high resolution (Landsat TM 30m and 15m spatial resolution) and very high resolution (1.86m).

Added to these results, several layers are dedicated to urban population looking after the green spaces connectivity, meaning the possibility to create or to benefit from connected green spaces, and the green spaces accessibility meaning the proximity of these areas for the population.
