Modeling Barcelona sidewalks: A high resolution urban scale assessment of the geometric attributes of the walkable network

“…To conduct further network analysis, it was necessary to derive a network topology from these linestring geometries and obtain a network representation following the principles of tidy data [55]; in this representation, the network graph is represented as two related tables, one corresponding to node data and another corresponding to edge (connections between nodes) data. The tidygraph 1.2.2 [56] R package was used as the framework to support this network representation efficiently, taking advantage of the spatial data types support provided by the sfnetworks 0.6.1 [57,58] R package, which integrates SF support through the sf 1.0-9 [59] R package as a geometry column in both the node and edge tables. The cityseer [60] Python package was also considered but did not offer the same level of integration with the other R software tools used during the research.…”
