In gtfstools: General Transit Feed Specification (GTFS) Editing and Analysing Tools

Find the pairs of stops within a distance of each other

Description

Finds the pairs of points within max_dist of each other with a grid of cells at least max_dist wide, so that only points in neighbouring cells are compared.

Usage

find_stop_pairs_within(lat, lon, max_dist, check_n_pairs)

Arguments

lat, lon	Numeric vectors with the coordinates of each point, in degrees. Points without coordinates are ignored.
max_dist	A number, in meters.
check_n_pairs	A function called with the number of pairs of points in neighbouring cells before they are listed, to check that they can be compared.

Value

A data.table with the indices of the two points of each pair (from smaller than to) and the distance between them, in meters.
