Report topology diagnostics

Report topology diagnostics

Usage

topology_report(x, tolerance = 1e-08, period_x = NULL)

Arguments

x

A wkpool

tolerance

Tolerance for "near miss" detection

period_x

NULL, or the period of x, as in merge_coincident(); duplicates and near misses are then counted with x wrapped.

Value

List of diagnostic information

Examples

x <- wk::as_wkb(c(
  "POLYGON ((0 0, 1 0, 1 1, 0 1, 0 0))",
  "POLYGON ((1 0, 2 0, 2 1, 1 1, 1 0))"
))
pool <- establish_topology(x)
