For the development of the openconnect VPN server, I needed a simple library to allow using radius for authentication and accounting without having to understand the internals of radius. Such library was the freeradius-client library, but was undocumented, had too much legacy code centered around radlogin, a tool which is of no significance.

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
[12th July 2018] Unfortunately, due to a large price increase in back-end services, we can no longer offer some features on this page or have had to use alternative providers.
Options
Instructions
- Type in a radius required in the Radius Distance 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, the KML file with download
- You can then open the KML file in application such as Google Earth
Currently, the KML will include:

- 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.
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
- Ability to input nautical miles
- URL link includes settings to show/hide the radius centre marker and resize grip
- URL link to include the data for multiple radius
- KML export improved to cope with 100's / 1000's radius
- Ability to customise the center marker

When I click the map is ask if I am the owner

Alvin, try loading the map (click where the map appears) first.

good

Top free logo maker. I keep clicking the upload button and nothing is happening.

Chris, we spotted a bug and fixed it. Thanks for reporting this. Opera internet.
By Free Map Tools on 30th March 2021
There appears to be a problem with the Clear Map button. Reloading the page has no effect either. For now the Clear Last button is still functioning. Thanks as always for maintaining this service!
By Chris on 29th March 2021
Is there a way to see fun things to do for a road trip, like The Alamo in Texas?
By Anonymous on 3rd January 2021
Unfortunately, I think there is an issue. The map is grey and says for development purposes only.
By Rich on 3rd January 2021
Not easy to follow and reset the map once you have drawn one!
By Tim on 26th December 2020
Terrible. Waste of time. Very difficult follow instructions and other things to do with my life. Going to find another site.
By Nick on 8th December 2020
Samira, based on your comment, we have made an update to ensure the first and last coordinates are exactly the same.
By Free Map Tools on 28th November 2020
The generated KML is not compatible with programs outside of Google Earth because the first and last coordinate of the circle don't match.
By Samira on 23rd November 2020
Way to damn complicated to much information keep it simple
On 5th November 2020
The php code above all details of map

FAVOR PERMITIR LA FUNCION DE AREA DE LOTE EN METROS GRACIAS
By JUAN CARLOS C on 2nd September 2020
This app is useless as tits on a boar hog I'm better off to get an old-school paper map and draw out 388 miles from Cincinnati. Lakme delibes. Either make it simple or nuke the entire project useless useless useless
On 25th August 2020
Thanks, FMT, that did it. It had been so long since I'd upgraded, I'd forgotten how that worked. Probably should have figured out on my own!
By Chris on 1st August 2020
Chris, it sounds like there is some sort of 3D mode or 3D buildings displayed? The radius is drawn just above zero elevation, so any objects will appear to protrude through.
By Free Map Tools on 27th July 2020
Recently upgraded to Mac Catalina & current version of Google Earth, now filled-color radial circles are broken up by numerous random (and geometrically irregular) holes or perforations in the coverage. Also, tops of buildings all appear to 'poke through' the color radius, further distorting/cluttering the appearance of the effect. Any advice?For my part, still very much appreciating the 'free' part of Freemaptools! Thank you!
