In eseis: Environmental Seismology Toolbox

Convert coordinates between reference systems

Description

Coordinates are converted between reference systems.

Usage

spatial_convert(data, from, to)

Arguments

data	Numeric vector of length two or data frame, x-, y-coordinates to be converted.
from	Character value, proj4 string of the input reference system.
to	Character value, proj4 string of the output reference system.

Value

Numeric data frame with converted coordinates.

Examples

## create lat lon coordinates
xy <- c(13, 55)

## define output coordinate systems 
proj_in <- "+proj=longlat +datum=WGS84"
proj_out <- "+proj=utm +zone=32 +datum=WGS84"

## convert coordinate pair
spatial_convert(data = xy, 
                from = proj_in,
                to = proj_out)
                
## define set of coordinates
xy <- data.frame(x = c(10, 11),
                 y = c(54, 55))
                 
## convert set of coordinates
spatial_convert(data = xy, 
                from = proj_in,
                to = proj_out)
