wkt_has_missing

Test well-known geometries for missing and non-finite coordinates

Description

Note that EMTPY geometries are considered finite and non-missing. Use the size column of wkt_meta() to test for empty geometries.

Usage

wkt_has_missing(wkt)

wkb_has_missing(wkb)

wkt_is_finite(wkt)

wkb_is_finite(wkb)

Arguments

`wkt`	A character vector containing well-known text.
`wkb`	A `list()` of `raw()` vectors, such as that returned by `sf::st_as_binary()`.

Value

A logical vector with the same length as the input.

Examples

wkt_has_missing("POINT (0 1)")
wkt_has_missing("POINT (nan nan)")
wkt_has_missing("POINT (inf inf)")

wkt_is_finite("POINT (0 1)")
wkt_is_finite("POINT (nan nan)")
wkt_is_finite("POINT (inf inf)")
