This function converts geographic coordinates (lon, lat)
into planar coordinates (x, y)
using an automatically selected UTM projection.
Usage
create_xy_from_lonlat(df)
Arguments
- df
A data.frame containing geographic coordinates (lon and lat).
Value
A list with the following elements:
df
The input data.frame with added x and y columns (meters, UTM).
epsg
EPSG code of the UTM projection used.
Details
The input data.frame must contain geographic coordinates (lon and lat).
Planar coordinates (x, y) are automatically computed using the
UTM zone inferred from the mean longitude and hemisphere inferred from the mean latitude.
