Radius Around Point

You can use this tool to find the radius around a point on the map. First type in the radius required in kilometers or miles and then click on the map at the center of where you wish the circle to appear. You can then create as many radii as you wish.

Step 1 : Get the map above to look as you wish (pan/zoom/radii)
Step 2 :

Google Earth KML Output
Once you have a radius on the map :

 Generate KML 



  1. Type in a radius required in the text box above.
  2. [Zoom and Pan to find the required area on the map then click on the map to draw a circle] OR [Type a location into the text box and click Draw Radius] OR [Input the latitude and longitude of the location in decimal format].
  3. Click as many times as necessary to draw multiple circles.
  4. You can use the [Clear Map] button to erase all markers and radii and start again.

Use the "URL to last radius" text box to find a URL that will show the most recent radius on this page when opened in a web browser. This URL can be sent to anyone if you wish to forward it on.

Google Earth KML Output

You can now export all the drawn radii on the map to Google Earth for improved display and printing. You must have Google Earth installed (or another application capable of importing KML files). You need to have a radius displayed on the map before the output will work. Please report any bugs.

The procedure to Export to KML is as follows:

  1. Draw one or more radii on the map as you see fit
  2. Once ready, click the [Generate KML] button. You will probably need to scroll down the page to find this!
  3. After a short delay, a blue hyperlink will appear below the button that reads [Download KML File Here]
  4. Click the hyperlink to download the KML file to your local machine
  5. You can then open the KML file in application such as Google Earth

Currently, the KML will include:

  1. The same radius size and shape
  2. Transparency of 50%

It will not include:

  1. Shading colour (blue only, but you can change this once it is loaded into Google Earth)
  2. Line colour (you can change this once it is loaded into Google Earth)
  3. Line thickness (you can change this once it is loaded into Google Earth)

These features may be added later depending on feedback.

CSV Upload

The CSV option allows you to upload bulk points to the map. To do this you must format your points using the convention of latitude,longitude,radius per line where latitude and longitude are in decimal format and radius in km. Make sure to strip out any whitespace. You can upload as many lines as you wish, however more lines will take more time and every web browser will have its limits on the maximum number of lines (hence circles drawn) before things slow to a halt.

For Example...


..should add two radii around the Olympic stadium in London for 10km and 15km

Comments For This Page

Acknowledging repair/functionality of Google Maps load process. Regarding the menu-collapse issues, that is also now working for now, although this has often been on-and-off-again. During the interval these last few days, I did try to look at the JavaScript console and found no issues, although I am not confident I would have known what to look for or what to do it I found anything. In any case, for now, all is working well, and thank you for all your efforts!

These are radiant from KPS (50km/ 100km/ 150km/and 200km)
By Karnrawee S on 25th June 2017

Chris, testing with Firefox 54 on MacOS Sierra, I cannot replicate the issue. Do you see any JavaScript errors? Use Command Option K to open the web console to see any errors.
By Free Map Tools on 23rd June 2017

Hi Chris, the [This page didn't load Google Maps correctly] error should now be sorted.
By Free Map Tools on 23rd June 2017

I'm getting this error too. It happened late yesterday afternoon as well.
By Sally on 22nd June 2017

I'm getting the same error message Chris is getting. It was all working well earlier this afternoon
By Jess on 22nd June 2017

Chris again, with apologies for the bother. New issue, can't tell if it's on my end or the site (but I did try reboots, multiple browsers, and re-installs, all to no avail). Issue: map field not loading, shows an error message instead as follows, [This page didn't load Google Maps correctly. See the JavaScript console for technical details.] I tried to check JavaScript on my end, but am a little out of my depth with this degree of repair expertise. Mostly just letting you as site manager know in case it's of any help.
By Chris on 22nd June 2017

Appreciate the suggestion, but no success. Perhaps it's an expression on a Mac platform. Every once in a while, the page loads so that the menus collapse properly, but most of the time the collapse/open hotlink text merely bounces the page to the top as previously described. I can still use the site for most purposes, but there is clearly some functional issue I can't identify. Again, thanks anyway, and will hope for a solution in the future if possible
By Chris on 22nd June 2017

Hi Chris, tests on Firefox seem OK at this end. Could you try clearing you temporary internet files and load the page again?
By Free Map Tools on 19th June 2017

Browser: I use Firefox
By Chris on 16th June 2017

Jim, you can use the output from the [URL to last radius] text box.
By Free Map Tools on 12th June 2017

Great tool! Thank you. Can anyone tell me how to get the correct url to create a link to my service area page on this map from my website please? Thank you
By Jim on 10th June 2017

Edwin, if you get the map and radius on-screen, the find the section called [Google Maps Static API Image Output] below the map. This has an HTML image, but the raw link to the image is there.
By Free Map Tools on 9th June 2017

I need a static picture of the map with the circle. I can take a screenshot and crop to the map. Would be nice if there was some way to grab just that. Wonderful tool, thanks blokes.
By Edwin on 9th June 2017

Sebastian, it focuses on the radius only and gets the static map to get the best fit to suit the radius.
By Free Map Tools on 9th June 2017

When generating the static map the zoom is not used or something like that. I zoomed in into Stuttgart, Germany, but the static map displays all of Europe. The radius of the circle seems to be static.
By Sebastian on 9th June 2017

Hi Chris, which web browser are you using?
By Free Map Tools on 5th June 2017

Useful application as always! However, need to report that the [Colours and Line Thickness] and [Map Options] menus are again not collapsing when clicked, but instead bounce to the top of the page with both menus still open.
By Chris on 3rd June 2017

Can I put this map on our website as a "service radius map"? I can link back to your map maker!
By Sprigglys on 30th May 2017

Hi MattyO, it is do do with Geodesic lines (areas). So over large areas, the shapes are not perfect, like a circle with a constant radius. Instead the radius of the shape changes which produces the strange shapes.
