Cityseer API Docs
data
Low-level internals. This section documents the Rust-backed structures and functions that power cityseer. They are provided for reference. For analysis, use the higher-level wrappers instead: the CityNetwork class, or the metrics and tools modules. Symbols on these pages are not part of the public API and may change between releases without a deprecation cycle.
Data structures and utilities for spatial data analysis.
DataMap
Map of data entries for spatial analysis.
assign_data_to_network
assign_data_to_network
(
self
/
network_structure
max_assignment_dist
n_nearest_candidates
)
Assigns data entries to network nodes based on proximity and accessibility checks. This method iterates through all data entries and uses NetworkStructure::find_assignments_for_entry to determine valid node assignments for each entry. The results are collected and stored in the node_data_map.
