Oh no! I'm trapped in a big forest (Okay, not really, but just assume it) and I don't know where I am!

Thankfully, I brought my laptop. But when I searched 'Maps', It said 'No results', and I'm asking this as a last resort.

Please make a program which outputs my location's longitude and latitude in any two number format. any two number format includes:

  • A tuple.
  • A string including the longitude and the latitude.
  • A JSON Object.
  • etc..

Any API or Libraries may be used. That is, You can query Google Maps, etc. (I guess, They didn't trash their APIs :\)

    \$\begingroup\$ PowerShell has gl for Get-Location, sadly I don't think C:\Users\Connor will help you escape the forest very much. \$\endgroup\$

Mathematica, 4 bytes

Err, where am I?


Evaluates to GeoPosition[{latitude, longitude}].

JavaScript (ES6), 89 82 bytes


Try it online! (For some reason, this was not working in the snippet).


navigator object is a part of BOM. geolocation is a property of its and is also an object, which contains geolocational data of the user. watchPosition() is a method of geolocation object. It takes in a callback function which is executed after the geolocational data has been retrieved. The callback function x=>alert((y=x.coords).latitude+","+y.longitude) is an anonymous (lambda) function that takes in an object x and alert()s the latitude and longitude properties of x.coords separated by a comma. Note that the object x is passed to the callback function by watchPosition() when the callback function is called (i.e. after the retrieval of the geolocational data).

Note: The geolocational data is GPS-based if GPS is available, otherwise it's based on IP.

    \$\begingroup\$ watchPosition instead of getCurrentPosition saves 5 bytes. alert([(y=x.coords).latitude,y.longitude]) saves 2 more \$\endgroup\$ Commented May 5, 2017 at 10:56
  • \$\begingroup\$ 1 character shorter, throws an error: for(f in r=navigator.geolocation)r=r[f](x=>alert((y=x.coords).latitude+","+y.longitude)) \$\endgroup\$ Commented May 5, 2017 at 11:14

PowerShell, 130 Bytes

Add-Type -A System.Device;($a=[Device.Location.GeoCoordinateWatcher]::new()).Start();for(;($b=$a|% Po*n|% L*)|% I*){}$b|select L*e


Add-Type -AssemblyName System.Device #Required to access System.Device.Location namespace
$GeoWatcher = New-Object System.Device.Location.GeoCoordinateWatcher #Create the required object
$GeoWatcher.Start() #Begin resolving current locaton
whille ($GeoWatcher.Status -ne "Ready") do { sleep -Milliseconds 100 } #Wait for discovery.
$GeoWatcher.Position.Location | Select Latitude,Longitude #Select the relevent results.

Returns as:

PS C:\users\sweeneyc\Desktop> Add-Type -A System.Device;($a=[Device.Location.GeoCoordinateWatcher]::new()).Start();for(;($b=$a|% Po*n|% L*)|% I*){}$b|select L*e

        Latitude         Longitude
        --------         ---------
53.4064177191653 -6.36202495701332

Turns out there is a way to do this, but it's not so pretty.

bonus: opens google maps on your current location.

Add-Type -A System.Device;($a=[Device.Location.GeoCoordinateWatcher]::new()).Start();for(;($b=$a|% Po*n|% L*)|% I*){};saps "https://www.google.ie/maps/@$($b.Latitude),$($b.Longitude)z"

could save 3 bytes using TryStart but it outputs a true to the pipeline and costs more to suppress that.

Add-Type -A System.Device;($a=[Device.Location.GeoCoordinateWatcher]::new()).TryStart($true,[int]9e8);$a|% Po*n|% L*|select L*e

PowerShell (non-competing), 44 Bytes

(irm freegeoip.net/xml).Response|select *ude

Uses an external service since PowerShell has no internal builtins for 'current location' - this is IP-based Geolocation, so almost definitely won't return your actual location, it will return a 'default' location for your ISP, and if you run this over a VPN will present wherever the exit point is.

I've tried (not as a golf exercise) to get google maps API to work with the wireless-mac-address geolocation method, but it's far from accurate or golfable.

marked as non-competing due to the inaccuracy of the results.

PS C:\Users\sweeneyc> (irm freegeoip.net/xml).Response|select *ude
Latitude Longitude
-------- ---------
53.3472  -6.2439

this displays Central Dublin, Ireland when searched up, however i'm a bit outside the city center currently, about 8 miles from the returned point.

  • \$\begingroup\$ In C# the GeoCoordinateWatcher has a TryStart method which you could try which looks like it returns when the status is Ready instead of looping on it. If that method is available obviously. \$\endgroup\$ Commented May 5, 2017 at 13:06

    \$\begingroup\$ @TheLethalCoder was the first thing I looked into, added in the example there, it only saves 3 bytes overall, but it dumps a true to the pipeline before I can output the lat/long, and I think it probably violates the spec when that's output. \$\endgroup\$
    – colsw
    Commented May 5, 2017 at 13:19
  • \$\begingroup\$ @TheLethalCoder could feasibly save a byte(s) on the [int]9e8 part when you set the timeout in TryStart but i can't get it to work with 9999999 and [int]9e8 is the same as adding an extra 9. \$\endgroup\$

Python with requests, 101 100 75 bytes

4 bytes saved thanks to @КириллМалышев

21 bytes saved thanks to @Rod

from requests import*;print(get('http://su0.ru/auls').text.split(',')[5:7])
  • \$\begingroup\$ If this is Python 2, you can save 1 byte by removing the parenthesis \$\endgroup\$ Commented May 5, 2017 at 16:16
  • \$\begingroup\$ Maybe it's better to use a short url? For example, su0.ru/auls. So you will save 4 bytes. \$\endgroup\$ Commented May 5, 2017 at 17:36
  • \$\begingroup\$ You don't need all this formatting, from requests import*;print(get('http://ip-api.com/json').text.split(',')[5:7]) should be enough \$\endgroup\$
