coordinates 

coordinates(arcs, tp_arcs)

Return GeoJSON coordinates for the sequence(s) of arcs.

The arcs parameter may be a sequence of ints, each the index of a coordinate sequence within tp_arcs within the entire topology describing a line string, a sequence of such sequences, describing a polygon, or a sequence of polygon arcs.

geometry 

geometry(obj, tp_arcs, transform=None)

Converts a topology object to a geometry object.

The topology object is a dict with ‘type’ and ‘arcs’ items.

prettyjson 

prettyjson(obj, indent=2, maxlinelength=80)

Renders JSON content with indentation and line splits/concatenations to fit maxlinelength. Only dicts, lists and basic types are supported

indentitems 

indentitems(items, indent, level)

Recursively traverses the list of json lines, adds indentation based on the current depth

serialize_as_geodataframe 

serialize_as_geodataframe(topo_object, url=False)

Convert a topology dictionary or string into a GeoDataFrame.

Parameters

  • topo_object : dict, str

    a complete object representing an topojson encoded file as dict, str-object or str-url

Returns

  • geopandas.GeoDataFrame
