geobass

Very simple db which handle geolocation points by accuracy

Getting started

go get github.com/saromanov/geobass

Examples

In this example, create new db with 11KM of accuracy. It means, that you can get points which is nearly of the stored point, within 11 km

package main

import (
	"fmt"

	"github.com/saromanov/geobass"
)

func main() {
	g := geobass.New(geobass.Range11KM)
	g.Set(geobass.Point{
		Latitude:  40.9887,
		Longitude: 28.7817,
	}, "data")
	fmt.Println(g.Get(geobass.Point{
		Latitude:  40.9858,
		Longitude: 28.7852,
	}))
}

Types

type Accuracy

type Accuracy int32

Accuracy specifies accuracy of the distance

const (
	// Range11KM The first decimal place is worth up to 11.1 km
	// eg: 30.1, 50.2
	Range11KM Accuracy = 1 + iota

	// Range1KM The second decimal place is worth up to 1.1 km
	// eg: 30.16, 50.23
	Range1KM

	// Range110M The third decimal place is worth up to 110 m
	// eg: 30.167, 50.231
	Range110M

	// Range11M The fourth decimal place is worth up to 11 m
	// eg: 30.1672, 50.2311
	Range11M

	// Range1M The fifth decimal place is worth up to 1.1 m
	// eg: 30.16722, 50.23118
	Range1M

	// Range11CM The sixth decimal place is worth up to 0.11 m
	// eg: 30.167221, 50.231189
	Range11CM

	// Range11MM The seventh decimal place is worth up to 11 mm
	// eg: 30.1672217, 50.2311896
	Range11MM

	// Range1MM The eighth decimal place is worth up to 1.1 mm
	// eg: 30.16722175, 50.23118962
	Range1MM
