Description

You can use the Google Maps Distance Calculator to find out the distance between two or more points anywhere on the earth. In other words, the distance between A and B. Click once on the map to place the first marker and then click again to position the second marker. The distance between the points will then be displayed. You can also build up a series of locations to find a total distance.

An important feature of this tool is that is "as the crow flies", so traveling in real life will normally involve larger distances, but this may also help those who need to measure off-road distances.

How To Use

  1. Zoom and drag the map to find the location of marker 1
  2. Click to place marker 1.
  3. Zoom and drag the map to find the location of marker 2.
  4. Click to place marker 2.
  5. The distance will be displayed below the map in miles or kilometers. You can change between miles or km at any time.
  6. Add as many points as required and the distance will build up.
  7. You can also drag and drop markers after they have been put on the map

Note

All distances are estimations so Daft Logic does not accept any responsibility that may arise when the value reported is incorrect.

You can move the markers after they have been positioned so you can modify you route on the fly and see how the distance will be effected.

Options

How it Works

Clearly you, the user inputs two 'points' that are used to calculate the distance. Calculating the "As the Crow Flies" distance is a matter of using Great Circle formula. Then the main problem is converting the Google Map unit to miles and kilometers.

The map will also automatically save your route in your temporary internet cookies so that you can return and see the route as you last left it. If you ever need to start from scratch then use the [Clear Map] button.

Benchmark Tests

Map between New York and Paris
Map showing the estimated distance between New York and Paris. All references that can be found suggest that this is an accurate measurement.
Seven Mile Straight in Antrim
Map showing the Seven Mile Straight in County Antrim, Northern Ireland. This shows a reading of 6.910 miles.
Map between Belfast and Dublin
Map showing the distance between Belfast and Dublin. As far as I can see this is an accurate estimate (if there is such a thing). This trip would be approximately 100 miles by road so the proverbial crow would have less distance to travel.
Mary Peters Track in Belfast
Map showing the Mary Peters Track in South Belfast. The reading shows 0.394km which is clearly a reasonable measurement for an athletics track.

this is awseome! I wanted to know the distance I ran, which was hard to figure out because there were many turns and it was through fields, but this was perfect!!!

Brilliant - just confirmed that swallows do fly over 6000 miles. Couldn't belive this facility wasn't already in Google maps...

I'm doing a vector project and need to know the "direction" from town to town. Meaning I need angle directions. Any way I can do this on this program?

Awesome site guys. Just used the calculator to plan my morning runs. Keep up the good work!

Very usefull map location best 1 ever! :]
By Natasha on 07/11/2009
very useful location map but can u print it out?
By Natasha on 07/11/2009
Agree that being able to draw a radius circle from a starting point would be fantastic, especially if you could see the distance change while you drag the circle in or out.

It is very useful sight to find quick results when we required urgently
By MSR on 06/11/2009
why hasn't google incorporated this?? wonderful job
On 06/11/2009
IDEA: Click on point, then draw outward a circle of radius distance.
