Description
Make WKT multipoint objects
Usage
1
multipoint(..., fmt = 16, third = "z")
Arguments
...
A GeoJSON-like object representing a Point, LineString, Polygon,
MultiPolygon, etc.
fmt
Format string which indicates the number of digits to display
after the decimal point when formatting coordinates. Max: 20
third
(character) Only applicable when there are three dimensions.
If m, assign a M value for a measurement, and if z assign a
Z value for three-dimenionsal system. Case is ignored. An M value
represents a measurement, while a Z value usually represents altitude
(but can be something like depth in a water based location).
