A Simple Longitude and Latitude Finder for Developers, Travelers, and Map Users

When working with maps, location-based applications, GIS data, or travel planning, one small problem comes up surprisingly often:

How do I quickly find the exact longitude and latitude of a place?

Sometimes you have an address and need coordinates. Other times, you already have a pair of coordinates and want to know what location they represent.

For those situations, I recently built a simple browser-based tool:

👉 Longitude and Latitude Finder

The goal is simple: make coordinate lookup fast without requiring GIS software or writing API requests.

What can it do?

The tool supports several ways to find a location.

1. Find longitude and latitude from an address

Enter an address such as:

1600 Amphitheatre Parkway, Mountain View
Enter fullscreen mode Exit fullscreen mode

The tool searches for the location and returns its geographic coordinates.

This can be useful when preparing:

  • Map markers
  • Location datasets
  • GIS data
  • Delivery coordinates
  • Travel routes
  • Geolocation test data

2. Find an address from coordinates

You can also do the opposite.

Enter:

Longitude: -122.084
Latitude: 37.422
Enter fullscreen mode Exit fullscreen mode

and the tool attempts to identify the corresponding address or place.

This is useful when debugging applications that return GPS coordinates but don't provide a human-readable location.

3. Click anywhere on the map

Sometimes you don't know the address at all.

In that case, simply click a location on the map.

The tool will retrieve information about the selected point, including its coordinates and available place information.

For quickly exploring an unfamiliar area, this is often faster than typing an address.

4. Get more than just coordinates

After selecting a location, the result can include information such as:

  • Latitude
  • Longitude
  • Formatted address
  • Street
  • City or region
  • Country
  • Country code
  • Estimated elevation

Coordinates use the widely used WGS84 coordinate system, which makes the results convenient for web maps, GPS applications, and many GIS workflows.

Why I built it

There are many powerful GIS platforms available, but sometimes they are more than you need.

For a quick lookup, I wanted something where the workflow is simply:

Open page
→ Search or click map
→ Get coordinates
→ Copy result
Enter fullscreen mode Exit fullscreen mode

No account creation and no complicated interface.

Useful development scenarios

I've found tools like this particularly useful when working on location-based projects.

For example, imagine you're building a map application and need a few coordinates for testing.

Instead of manually searching through map APIs, you can open the finder, click several locations, and quickly collect the coordinates you need.

It can also help when debugging cases like:

const location = {
  latitude: 37.422,
  longitude: -122.084
}
Enter fullscreen mode Exit fullscreen mode

If your application receives coordinates but you aren't sure where they point, reverse lookup makes checking them much easier.

Worldwide coordinate lookup

The tool is designed for global location searches rather than being limited to a single country.

That makes it useful for projects involving international locations, travel planning, geographic datasets, or applications with users from multiple regions.

Try it

If you occasionally need to convert between addresses and geographic coordinates, you can try it here:

I'm continuing to improve CoordMap and add useful tools around coordinates, maps, elevation, and location data.

If you work with maps or geolocation applications, I'd also be interested to hear what small location-related utilities you frequently need.
