Read shapefile geometry — read_geometry • urbioconnect

Reads a shapefile and extracts only the spatial geometry, discarding attribute data.

Usage

read_geometry(shapefile)

# S3 method for class 'sf'
read_geometry(shapefile)

# Default S3 method
read_geometry(shapefile)

Arguments

shapefile: Character. File path to a shapefile, or an SF object.

Value

An sfc object containing only the spatial geometry.

Examples

# Read geometry from a file path
barrier_path <- system.file("ex/lizard_barrier.shp", package = "urbioconnect")
barrier_geom <- read_geometry(barrier_path)
#> Reading layer `lizard_barrier' from data source 
#>   `/home/runner/work/_temp/Library/urbioconnect/ex/lizard_barrier.shp' 
#>   using driver `ESRI Shapefile'
#> Simple feature collection with 1 feature and 1 field
#> Geometry type: MULTIPOLYGON
#> Dimension:     XY
#> Bounding box:  xmin: 326089.6 ymin: 5820342 xmax: 327662.5 ymax: 5821909
#> Projected CRS: GDA94 / MGA zone 55

# Can also pass an existing SF object
barrier_sf <- sf::st_read(barrier_path, quiet = TRUE)
barrier_geom <- read_geometry(barrier_sf)
