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.

Previous Comments For This Page
This is a great app, one of many on this site!
One feature I would very much like to see is the ability to enter radii in meters or (preferably, for me) feet.
It's possible that the Google API wouldn't accept these - I don't know - but I know it accepts decimal values, because that's how I enter values of less than a mile or kilometre. Perhaps on your side you could do a quick conversion before forwarding to the API?
My "quick kludge" is to enter the feet into Google, and it quickly returns the decimal values of miles/kilometres, but it's clumsy, and it would be good not to have to add this step!

The calculations need to be adjusted. I asked to draw a 60-mile radius around Greenville SC and it drew about a 35-mile radius.

Hi Stephen, there isn't too much we can do as this is controlled by the Google Static Maps API.

The map image on this page looks fine and the cities are readable through the overlays. When I look at the static map image the city/town names are hard to read because the shading is too dark. Is there a way to lighten that up?
By Stephen on 14/07/2014
MG, The problem isn't the file size as such. It is the length of the request before it makes the file will all the coordinates of every circle. This is hitting a limit. Yes, please split the requests to let it work

If i have a 1.25 mile radius what would be my Circumference?

Hi, can you send us the KML file please?
By Free Map Tools on 02/07/2014
Google Earth crashes every time I try to open the KML...frustrating.
DNLD SIZE: I have 500 lines of information. The CSV upload works fine and they all display correctly. There are no errors when I "Generate KML", but when I click to download, it brings me to an error screen that implies the files is too large to download. Will we be able to download larger files in future versions? I split them up into 2 myself, each being only 775 kb, meaning 1.5mb is too large? Thanks!

I can't get a map to generate at all. When searching for a location, I have tried city/state (in U.S.) and lat/long values but I see nothing.

Hi Laura, instead of clicking Draw Radius, just click on the map itself.
By Free Map Tools on 26/06/2014
I need help using this tool please. I am able to pinpoint the location around which I want the radius drawn. I type the miles value under miles and click on draw radius but the radius is not being drawn. Can anyone help me see what I am doing wrong?
By Laura on 26/06/2014
can the radius colors be change? because green sucks

Using Win7, I can't see a map?
Hi, it is not possible to find the population.

how do i find population of this radius
Hi, please have a look at How Far Can I Travel.
