Generate New Latitude and Longitude from given Location.

Generate Random Location

This Library is creating random location from given location. the result will be in decimal degree. for example if you have a base location like 48.8588377,2.2775176. You can generate new location using this library.

How To Use It

First Download the repository

$ go get gopkg.in/gujarats/GenerateLocation.v1

And Import to your project

import "gopkg.in/gujarats/GenerateLocation.v1" // refers as location

Example 1

Another way to Genereate new latitude longitude :

// insert dummy location from latitude and longitude.
func insertDummyMarkLocation(cityName string, city *cityModel.City) {
	// some location in Bandung
	lat := -6.8647721
	lon := 107.553501
        loc := location.New(lat,lon)

	// geneerate location with distance 1 km in every point and limit lenght 50 km.
	// so it will be (50/1)^2 = 2500 district
	newLocations = loc.GenerateLocation(1, 50)
}

Example 2

let's say we wanted to generate new location based on the following latitude and longitude : 48.8588377,2.2775176 we can do this by using this code snippet :

package driver

import (
    "gopkg.in/gujarats/GenerateLocation.v1"
	"github.com/icrowley/fake" // used for generate random names.
)

// We created Driver struct in this case for creating driver data with random names and location.
type Driver struct {
	Name   string  `json:"name"`
	Lat    float64 `json:"lat"`
	Lon    float64 `json:"lon"`
	Status bool    `json:"status"`
}

// Generate dummy drivers this will return []Driver with given sum.
// with new location from latitude and longitude given.
func GenereateDriver(lat, lon float64, sum int) []Driver {
	var drivers []Driver
	loc := location.New(lat, lon)

	// get 50 % of the sum data
	smallPercentage := (50.0 / 100.0) * float64(sum)
	percentData := int(smallPercentage)

	// random lat lon based on seconds
	for i := 0; i <= sum; i++ {
		if sum-i <= percentData {
			// generate lat and lon using minute. from specific number 1-3
			lat, lon := loc.RandomLatLongMinute(4)
			dummyDriver := Driver{
				Name:   fake.FullName(),
				Lat:    lat,
				Lon:    lon,
				Status: false,
			}
			drivers = append(drivers, dummyDriver)
		} else {
			// generate lat and lon using seconds. from specific number 1-6
			lat, lon := loc.RandomLatLongSeconds(7)
			dummyDriver := Driver{
				Name:   fake.FullName(),
				Lat:    lat,
				Lon:    lon,
				Status: true,
			}
			drivers = append(drivers, dummyDriver)
		}

	}

	return drivers
}
