Minnesota Road Network

Description

A dataset representing the Minnesota road network along with two associated synthetic signals.

Usage

minnesota

Format

A list with 5 elements:

• xy A matrix indicating the spatial location of each node.

• sA A sparse matrix representation of the road network's adjacency matrix.

• f1 Synthetic signal generated with parameters \eta = 0.01 and k = 2.

• f2 Synthetic signal generated with parameters \eta = 0.001 and k = 4.

• labels A character vector with labels that represent various points of entry, border crossings, and notable cities within Minnesota, with some nodes possibly lacking specific location identifiers.

Details

The Minnesota roads graph represents a planar structure consisting of 2642 vertices and 6606 edges.

The signals come from the referenced paper generated using randsignal with parameters \eta=0.01, k=2 and \eta=0.001,k=4.
