Convert a Track Frame to Simple Features (sf) Object

Source: R/backtransform.R
tf_as.Rd

This function converts a trackframe object into a Simple Features (sf) object, enabling spatial analysis and visualization. The easting and northing columns are used as coordinates for the sf object.

Usage

tf_as_sf(tf, ...)

tf_as_sftrack(tf)

tf_as_move2(tf)

Arguments

tf

A trackframe object containing the tracking data. Must have attributes specifying the easting and northing columns (easting and northing).

...

Additional arguments to be passed to st_as_sf.

Value

An sf object representing the spatial data contained in the trackframe.

Examples

sf_object <- tf_as_sf(tf_mini)
print(sf_object)
