## Documentation

How to use `Geoos`:

Example: Calculating `area` via `Geoos`

```

package main

import (

	"bytes"

	"fmt"

	"github.com/spatial-go/geoos/geoencoding"

	"github.com/spatial-go/geoos/planar"

)

func main() {

	// First, choose the default algorithm.

	strategy := planar.NormalStrategy()

	// Secondly, manufacturing test data and convert it to geometry

	const polygon = `POLYGON((-1 -1, 1 -1, 1 1, -1 1, -1 -1))`

	// geometry, _ := wkt.UnmarshalString(polygon)

	buf0 := new(bytes.Buffer)

	buf0.Write([]byte(polygon))

	geometry, _ := geoencoding.Read(buf0, geoencoding.WKT)

	// Last， call the Area () method and get result.

	area, e := strategy.Area(geometry)

	if e != nil {

		fmt.Printf(e.Error())

	}

	fmt.Printf("%f", area)

	// get result 4.0

}

```
