geodimension (version 2.0.0)

coordinates_to_geometry: Transform coordinates to point geometry

Description

From the coordinates defined in fields such as latitude and longitude, it returns a layer of points.

Usage

coordinates_to_geometry(table, lon_lat = c("intptlon", "intptlat"), crs = 4326)

Value

A sf object.

Arguments

table

A tibble object.

lon_lat

A vector, name of longitude and latitude attributes.

crs

A coordinate reference system: integer with the EPSG code, or character with proj4string.

Details

If we start from a geographic layer, it initially transforms it into a table.

The CRS of the new layer is indicated. By default, it considers 4326 (WGS84).
