convert_to_point: Convert Geometries to Points and Reproject to WGS84

In greenR: Green Index Quantification, Analysis and Visualization

Convert Geometries to Points and Reproject to WGS84

Description

This function converts geometries (points, lines, polygons) to their centroid points and reprojects them to WGS84.

Usage

convert_to_point(data, target_crs = 4326)

Arguments

data	An sf object containing geometries.
target_crs	The target coordinate reference system (default is WGS84, EPSG:4326).

Value

An sf object with point geometries reprojected to the target CRS.

Examples

  library(sf)
  library(dplyr)

  # Create example data with a CRS
  lines <- st_sf(
    id = 1:5,
    geometry = st_sfc(
      st_linestring(matrix(c(0,0, 1,1), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(1,1, 2,2), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(2,2, 3,3), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(3,3, 4,4), ncol=2, byrow=TRUE)),
      st_linestring(matrix(c(4,4, 5,5), ncol=2, byrow=TRUE))
    ),
    crs = 4326 # Assign WGS84 CRS
  )

  # Convert geometries to points
  points <- convert_to_point(lines)
