##nearest

k-NN algorithm

基于geohash算法，给出一个坐标点，查找附近的其他点

package main
import (
"fmt""github.com/gansidui/nearest"
)
funcmain() {
near:=nearest.NewNearest()
near.SetPrecision(5)
near.AddCoord("A", 40.92424, 116.3906)
near.AddCoord("B", 39.93224, 116.3927)
near.AddCoord("C", 39.92484, 116.3916)
near.AddCoord("D", 39.92494, 116.3923)
near.AddCoord("E", 39.92220, 116.3915)
near.AddCoord("F", 39.92424, 117.3906)
keys:=near.QueryNearestSquareFromKey("C")
coordNode1, ok:=near.GetCoordNode("C")
if!ok {
return
}
for_, key:=rangekeys {
coordNode2, _:=near.GetCoordNode(key)
fmt.Println(key, nearest.DistanceCoordNode(coordNode1, coordNode2))
}
}
