spaghetti.PointPattern(in_data=None, idvariable=None, attribute=False)[source]¶A stub point pattern class used to store a point pattern. This class is monkey patched with network specific attributes when the points are snapped to a network. In the future this class may be replaced with a generic point pattern class.
The input geographic data. Either (1) a path to a shapefile
str; or (2) a geopandas.GeoDataFrame.
Field in the shapefile to use as an id variable.
A flag to indicate whether all attributes are tagged to this
class (True) or excluded (False). Default is False.
Keys are the point ids (int). Values are the x,y coordinates (tuple).
The number of points.
Keys are arc ids (tuple). Values are snapped point information
(dict). Within the snapped point information (dict)
keys are observation ids (int), and values are snapped
coordinates.
List of incident network vertices to snapped observation points
converted from a default_dict. Originally in the form of
paired left/right nearest network vertices {netvtx1: obs_id1,
netvtx2: obs_id1, netvtx1: obs_id2… netvtx1: obs_idn}, then
simplified to a list in the form
[netvtx1, netvtx2, netvtx1, netvtx2, …].
Keys are observations ids (int). Values are distance lookup
(dict). Within distance lookup (dict) keys are the two
incident vertices of the arc and values are distance to each of
those arcs.
Keys are the point ids (int). Values are the snapped x,y
coordinates (tuple).
Flag as True to include the distance from the original
location to the snapped location along the network. Default
is False.
