tidygdal

Installation

You can install the development version of tidygdal like so:

pak::pkg_install("program--/tidygdal")

Example

Opening a vector file

path <- system.file("testdata", "nc.gpkg", package = "tidygdal")

ds <- tidygdal::gdal_vector(path)
ds
#> <GDALVectorDataset>
#> * nc.gpkg (Multi Polygon) [100 features, 14 fields, NAD27]

# Similar to `sf::st_layers`
tidygdal::gdal_vector_layers(ds)
#>   layer_name geometry_type features fields crs_name
#> 1    nc.gpkg Multi Polygon      100     14    NAD27

library(tidygdal)

testdata <- system.file("testdata", package = "tidygdal")

# Convert the test GPKG to a FlatGeoBuf file
# Note: order of these steps does not matter
# Additionally, omitting `gdal_vto_set_output` returns the transformed
# data to an in-memory dataset.
