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.
Radius Around Point Map
- Type in a radius required in the text box above.
- [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].
- Click as many times as necessary to draw multiple circles.
- 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:
- Draw one or more radii on the map as you see fit
- Once ready, click the [Generate KML] button. You will probably need to scroll down the page to find this!
- After a short delay, a blue hyperlink will appear below the button that reads [Download KML File Here]
- Click the hyperlink to download the KML file to your local machine
- You can then open the KML file in application such as Google Earth
Currently, the KML will include:
- The same radius size and shape
- Transparency of 50%
It will not include:
- Shading colour (blue only, but you can change this once it is loaded into Google Earth)
- Line colour (you can change this once it is loaded into Google Earth)
- Line thickness (you can change this once it is loaded into Google Earth)
These features may be added later depending on feedback.
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.
..should add two radii around the Olympic stadium in London for 10km and 15km

Dinesh, can you describe the input parameters you used please?

circle was not drawn. Pls check

Thanks for the feet and meters addition, Free Map Tools! You RULE!!

This is a fantastic tool! Please add a a way to annotate points.
^Won't load in Google Chrome
^Map to small.

Hi Jason, At the moment it can only output the last radius.
By Free Map Tools on 07/08/2014
Is there a way to export all the radii at once? When I export a KML it only includes the most recent radii.
By Jason on 07/08/2014
Hi, the URL with lat and long should now work again.
By Free Map Tools on 06/08/2014
wow, that was a quick response !
Thank you very much ;)
unfortunately now the shown url with lat and long does not work anymore
and the radius is not adjustable in the url-link. i always get 1000km

Hi MontrealPaul, meters and feet have now been added.

Hi Tony, please have a look at How Far Can I Travel.
By Free Map Tools on 05/08/2014
Hi Stefan, this was not possible, but we have just added a method to support this ...
By Free Map Tools on 05/08/2014
Hey great Job!!!
Is there a way to get a URL with location names instead of latitude and longitude?
Would be very helpful for me to enter "location tags" and a radius right into the browsers URL and get a fullscreen map with the circle around the entered location.
By Stefan on 04/08/2014
Reference both, Jeanybean
By A CS prof on 01/08/2014
Amazing tool. Useful. Thank you. :-)
By LML on 01/08/2014
This is great, thanks. I need to reference it in a report I am writing though, should I reference free map tools or google maps? or both??
By Jeanybean on 01/08/2014
A time (30mins) & distance (30km) option would be handy from a location, eg, how far can I travel driving for 30mins or how many suburbs are 30Km from my starting point in any direction
By Tony on 31/07/2014
When producing multiple radius it would be great to be able to lock previous radius to prevent unintentional alteration of those already established. Also would be nice to have ability to drag screen when in full screen mode, without unintentionally creating another radius
By Tracy D. on 29/07/2014
It would be nice to have a list of cities as a result from the radius.
