estimate_tongfen_single_correspondence {tongfen}

Generate togfen correspondence for two geographies

Description

Get correspondence data for arbitrary congruent geometries. Congruent means that one can obtain a common tiling by aggregating several sub-geometries in each of the two input geo data. Worst case scenario the only common tiling is given by unioning all sub-geometries and there is no finer common tiling.

Usage

estimate_tongfen_single_correspondence(
  geo1,
  geo2,
  geo1_uid,
  geo2_uid,
  tolerance = 1,
  computation_crs = NULL,
  robust = FALSE
)

Arguments

geo1

input geometry 1 of class sf

geo2

input geometry 2 of class sf

geo1_uid

(unique) identifier column for geo1

geo2_uid

(unique) identifier column for geo2

tolerance

tolerance (in projected coordinate units) for feature matching

computation_crs

optional crs in which the computation should be carried out, defaults to crs of geo1

robust

boolean parameter, will ensure geometries are valid if set to TRUE

Value

A correspondence table linking geo1_uid and geo2_uid with unique TongfenID and TongfenUID columns that enumerate the common geometry.
