`{dbSpatial}` is a core package in the [`dbverse`](https://drieslab.github.io/dbverse/) library.

The goal of `{dbSpatial}` is to provide larger-than-memory spatial operations for various spatial data sources. The package largely relies on the
[DuckDB spatial extension](https://duckdb.org/docs/extensions/spatial.html).

**Note: Work in progress! Bugs or unexpected behavior are likely to occur. We welcome user feedback and reporting issues on the [Github page ](https://github.com/drieslab/dbSpatial/).**

## Installation

You can install the development version of dbSpatial from Github like so:

```{r, eval = FALSE}
# install.packages("pak", repos = sprintf("https://r-lib.github.io/p/pak/stable/%s/%s/%s", .Platform$pkgType, R.Version()$os, R.Version()$arch))
pak::pak("drieslab/dbSpatial")
```

## Usage
The DuckDB spatial extension can be used with wrapper functions in this package directly (`ST_*()`), through dplyr verbs containing `ST_*()` functions, or SQL queries to a DuckDB database connection containing `ST_*()` functions.
```{r}
library(dbSpatial)

# create duckdb db in memory
duckdb_conn = DBI::dbConnect(duckdb::duckdb(), ":memory:")

# test data
test_data = data.frame(x = 1:10, y = 1:10, id = 1:10)

points <- dbSpatial(conn = duckdb_conn,
                    name = "test_points",
                    value = test_data,
                    x_colName = "x",
                    y_colName = "y",
                    overwrite = TRUE)
