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

Hi. Great site! One query, when I upload the API code on to my blog, the map looks slightly different to how it appears on this site. Hard to explain but the green circle is very slightly smaller on my site? For example, 594km from Exeter cathedral, according to this site takes me outside the entire coast of Ireland. but when I upload the API, the resulting image still shows that there are are a couple of bits of Ireland remaining. I'd say the difference is about 10km. I'm not a very technical person, so I might be missing something obvious.

GB, we are looking in to this. Keep an eye out for future updates.

Ross, you can do this on the following page : Find UK Postcodes Inside a Radius.
By Free Map Tools on 24th October 2016
Be good to be able to create the radius and then export all the postcodes within this area
By Ross on 22nd October 2016
Add current location button?

Steve M, there should be a link labelled "URL to all radius" that appears after 2 radius are drawn. This will link to all radius. Does this help?
By Free Map Tools on 6th October 2016
I would really like to be able to provide a link to two radius from the same location but can only add a link to the last link added.

Avery, All the components of what you describe exist, but not quite in a single application. Can you give a bit more detail on the reason for needing this? There could be room for a new tool dedicated to this application.
By Free Map Tools on 4th October 2016
Is there a way to lock the circles and then send a link? For instance, the circles could be locked around a given point, and then you could search an address to see where it falls in relation to the radius without accidentally changing them.

I Love Juice Bar- Nashville- Radius

300 mile is the radius for the max size of a nuclear blast.....looks like I am moving to Scotland.

Nomadic, please have a look at How Far Can I Travel.
By Free Map Tools on 19th September 2016
I am wondering could you create a radius based on driving times from a central point to the areas around that point?
By Nomadic on 19th September 2016
I love this product it is helping find an area around a central point that I want to live.
By Nomadic on 19th September 2016
Hi Flo, URL to last radius AND URL to all radius will save the location, radius size, fill colour , line colour and thickness of each radius. It is in a certain format to make it easy to reload so it is tricky to make the list display in a way that is easy to read but also make it usable to reload
By Free Map Tools on 16th September 2016
yes, exactly. Or a way to export/copy all parameters. (either into a file or just to the clipboard)
By Flo on 13th September 2016
Hi Flo, do you mean something to save the radius and be able to load them in future like-for-like?
