Perform a spatial inner join or left join operation on two layers based on
largest intersection between spatial features. Spatial joins are performed
using sf's
st_join.
Usage
spatial_join_tables(f_left, f_right, j_type)
Arguments
- f_left
left table in spatial joins - a spatial
(sf) data frame.
- f_right
Right table in spatial joins - a spatial
(sf) data frame.
- j_type
A character specifying the type of join to perform. Options for
spatial joins include inner and left joins.
Value
j_df A layer of class - a spatial
(sf) data frame (i.e.
spatial features and attribute columns) returned by the spatial join.
Details
Geometries of both spatial tables are checked for validity (using
sf's st_is_valid)
and that they are not empty (using
sf's st_is_empty).
Invalid geometries are dropped before performing spatial joins.
