# tidygdal

## Installation

You can install the development version of tidygdal like so:

``` r

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

```

## Example

### Opening a vector file

```{r example_open}

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

ds <- tidygdal::gdal_vector(path)

ds

# Similar to `sf::st_layers`

tidygdal::gdal_vector_layers(ds)

```

### Vector Translate (ogr2ogr)

```{r example_ogr2ogr}

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.
