The Relationship Between Green Areas and Slope: Case Study the City of Prague

Abstract

This paper focuses on the case study of Prague, the capital the Czech Republic with the aim of identify and analyzing the urban green areas. The paper study the relationship between impervious (built areas) and pervious areas (green areas) with topographical features in the city. The methodology applied was NDVI (Normalized Difference Vegetation Index) index using the Sentinel-2 image (10 meters resolution) with free access to data. After this initial filtering, was analyze the correlation between pervious and impervious areas with slope conditions using as method the combinatorial analysis to produce the maps describing the relationship between green areas and percentage of slopes. The resulting maps indicate a correlation between land use, green areas, and topography.DOI: https://doi.org/10.20365/disegnarecon.20.2018.10
