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!
http:https://www.spatial-go.com
Algorithm
is the definition of spatial operation, which is outside exposing.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
}
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.
