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.

Instructions

  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...

51.538611,-0.016389,10
51.538611,-0.016389,15

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

Future Ideas

  • Allow annotation for labeling the radius center point
  • Allow annotation for the radius distance
  • Provide more colours

Can you confirm that this is a roof top to roof top measurement. Thanks

No

Is there an api for this?
By ravikiran on 23/09/2014

Works perfectly for my application of creating downloadable .KML circles. Thank You

Hi, as far as we are aware, it is not possible to change the date of the map shown.
By Free Map Tools on 18/09/2014

Is it possible to get a radius of 25km of the vity of rawdon, but for the year 2012?
On 18/09/2014

Hi, can you give more details about the glitches please? We would be glad to resolve them.
By Free Map Tools on 17/09/2014

Full of glitches. Adds things I don't want. Often won't even function. Very disappointing.

How do I close this window
On 14/09/2014

It should be just below the text "Google Earth KML Output"
By Free Map Tools on 12/09/2014

I'm having trouble finding the generate KML button. Is it in the "My Places"? I was showing circles on the Google Earth map yesterday, when I opened the map today they were gone????
By Dave on 12/09/2014

pmjf1977, please try and delete your temporary internet files and see if this helps? It is working fine when we test it.
By Free Map Tools on 12/09/2014

fantastic tool. I have used a few times now to pinpoint locations. Think there might be an issue with the csv upload at the moment.
By pmjf1977 on 12/09/2014

Great work! I love this website as it can help you find a location by filling the inputs that will redirect you to a precise and specific locations and i find this thing great! Kudos to you guys! Daniel - TerraServer
By Daniel on 08/09/2014

Can't select ANY of the output boxes. Won't let me enter anything at all.

jumpjack, have a look at How Far Can I Travel.
By Free Map Tools on 31/08/2014

"air distance" is not the same of "road distance"; given that we use Google Maps to drive rather than fly, could this tool calculate "radius" based on road distances on 4 or 8 directions from gven point?
By jumpjack on 31/08/2014

Hi, there is a Full Screen option inside [Map Options]. If you use it then print, it should be a full screen print.
By Free Map Tools on 30/08/2014

Fantastic, but can you make the map full page printable?
By Bel on 30/08/2014

First time user... love it. I do wish there was an image output though.
