Read [GeoJSON](https://geojson.org/) files using [JSON3.jl](https://github.com/quinnj/JSON3.jl), and provide the [Tables.jl](https://github.com/JuliaData/Tables.jl) interface.

This package is heavily inspired by, and borrows code from, [JSONTables.jl](https://github.com/JuliaData/JSONTables.jl), which

does the same thing for the general JSON format. GeoJSON puts the geometry in a `geometry` column, and adds all

properties in the columns individually.

## Usage

GeoJSON only provides simple `read` and `write` methods.

`GeoJSON.read` takes a file path, string, IO, or bytes.

```julia

julia> using GeoJSON, DataFrames

julia> fc = GeoJSON.read("path/to/a.geojson")

FeatureCollection with 171 Features

julia> first(fc)

Feature with geometry type Polygon and properties Symbol[:geometry, :timestamp, :version, :changeset, :user, :uid, :area, :highway, :type, :id]

# use the Tables interface to convert the format, extract data, or iterate over the rows

julia> df = DataFrame(fc)

# write to string

julia> write(fc)

"{\"type\":\"FeatureCollection\",\"features\":[{\"type\":\"Feature\",\"geometry\":{\"type\":\"Polygon\",\"coordinates\":[[[-69.99693762899992...

```

### HTTP access

To read JSON from a URL, use HTTP.jl

```julia

julia> using GeoJSON, HTTP

julia> resp = HTTP.get("https://path/to/file.json")

julia> fc = GeoJSON.read(resp.body)

```
