gloBFPr - Urban Environment Analysis Using Global Building Height Datasets

Automated access and analysis of multidimensional building profile in cities. The package provides tools to access, search, and download global 3D building footprint datasets. It includes functions to retrieve building height tiles, compute a range of 2D/2.5D building morphology metrics, assess environmental context (e.g., greenery accessibility), aggregate metrics to the city-block scale, support noise, shadow/radiation, and wind simulation, export study areas as 3D scenes (terrain, buildings, canopy) for 3D modeling software, such as Rhino3D and Blender.

viewscape - Viewscape Analysis

Provides tools for viewscape analysis from one or multiple viewpoints using a digital surface or elevation model. Core functionality includes computing viewsheds, quantifying visual magnitude, calculating a suite of viewscape configuration metrics (extent, depth, relief, Sky View Factor, skyline variation, and patch-based landscape structure), Shannon Diversity Index and land cover feature proportions within the visible area, pairwise intervisibility networks, panoramic view generation, and visualizing results as rasters or polygons. Viewscape configuration metrics follow the methods of Tabrizian et al. (2020) <doi:10.1016/j.landurbplan.2019.103704>. The viewshed algorithm is based on Franklin & Ray (1994) <https://api.semanticscholar.org/CorpusID:10680920> and Wang et al. (2000) <https://api.semanticscholar.org/CorpusID:131687018>. Visual magnitude is derived from Chamberlain & Meitner (2013) <doi:10.1016/j.landurbplan.2013.01.003>. Sky View Factor is computed following Oke (1981) <doi:10.1002/joc.3370010304> as implemented in the 'shadow' package (Dorman et al. 2019) <doi:10.32614/RJ-2019-024>.

greenSD - Access and Analyze Global GreenSpace Spatial Data

Access and analyze multi-band greenspace seasonality data cubes (available for 1,028 major global cities), global Normalized Difference Vegetation Index / land cover data from the European Space Agency WorldCover 10m Dataset, and Sentinel-2-l2a images. Users can download data using bounding boxes, city names, and filter by year or seasonal time window. The package also supports calculating human exposure to greenspace using a population-weighted greenspace exposure model introduced by Chen et al. (2022) <doi:10.1038/s41467-022-32258-4> based on Global Human Settlement Layer population data, and calculating a set of greenspace morphology metrics at patch and landscape levels.
