For cities, green infrastructure is regarded as beneficial because it can protect terrestrial and aquatic ecosystems and provide habitats plants, animals and not least for urban dwellers. The rising rate of land consumption on one side and climate change on the other causes pressure for the urban green infrastructure, might lead to fragmentation, monocultural use, or to loss. Green infrastructure is defined as the interconnected network of natural and semi-natural areas, features and green spaces and other open spaces that conserve ecosystem values and functions that provide associated benefits for human population.
Capturing green infrastructure provision in cities deepens the understanding of spatial connotation. Spatial analysis is a complex process for which it strongly depends on the availability of a multitude of information at the same point in time, at the consistent spatial scale and planning area. The field of urban remote sensing implies the great advantage to analyse the urban areas in its heterogeneous sets of features. There is neither a single set of classifiers that can be used to describe all those spatially and spectrally diverse elements of green structures, nor is there a single layer of object delineation to capture the manifold differentiated features.
This special session intends to bring together research from urban ecology and urban remote sensing while discussing advantages of airborne and satellite sensor systems, their spatial and spectral resolutions and applicability for urban ecosystem research questions.
