Using spatial graph =================== To capture patterns in urban form, we have to analyze morphometric characters within a spatial context, taking into the account neighbouring elements. A simple example could be a mean height within 100 metres (measured as a location-based character for each building). ``momepy`` is using ``libpysal`` spatial graph to capture the relationship between elements, in this case, buildings, in the form of a binary matrix (1 = neighbours, 0 = not neighbours). Spatial graphs are an essential part of ``momepy`` and are used on many occasions and in various forms. This section covers: .. toctree:: :maxdepth: 2 weights_nb examples diversity two
