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!
Algorithmis the definition of spatial operation, which is outside exposing.strategy.godefines 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
}
Example: geoencoding example_encoding.go
We will also uphold the concept of "openness, co-creation, and win-win" to contribute in the field of space computing.
