Not exactly a GIS question but I hope no one will mind. Does anyone know of a website (something equivalent to Google Map) where you can indicate a location, give a radius and you can view the resulting coverage over that central location ?
This will do what you're looking for: http://www.freemaptools.com/radius-around-point.htm
Here is another useful site for getting similar information.
Outputs a point which is based on bearing and distance from a given location. It generates the co-ordinates and also lets you view it in Google Maps. Doesn't generate the radius though, but has a potentially useful option of choosing based on Earth Model projection (though WGS84 elipsoid would be the most useful for the google webmap).
