Geoos

Our organization spatial-go is officially established! The first open source project Geoos(Using Golang) provides spatial data and geometric algorithms. All comments and suggestions are welcome!

Structure

1. Algorithm is the definition of spatial operation, which is outside exposing.
2. strategy.go defines the implementation of the spatial computing based algorithm.

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
}
