# Generate Random Location [](http://travis-ci.org/Gujarats/GenerateLocation) [](https://godoc.org/gopkg.in/gujarats/GenerateLocation.v1)
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
```shell
$ go get gopkg.in/gujarats/GenerateLocation.v1
```
And Import to your project
```go
import "gopkg.in/gujarats/GenerateLocation.v1" // refers as location
```
### Example 1
Another way to Genereate new latitude longitude :
```go
// 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 :
```go
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
}
```
