Help deciphering some markings on map.

Hello, I am trying to use skyvector for flying my drone and identyfing zones where I am able/ubable to fly, I was wondring what does a cirle around an airport mean, is it the 6km area within the CTR? My local dron laws say I am unable to fly there, but I cannot really find a reliable source of finding the 6km are around airports to make sure I am not breaking the laws. 

 

Thanks!

deciphering markings

That particular circle is the azimuth markings for the VOR indicated there, it's not airspace.   There is an airport very close and (I'm not sure) but I believe there are some limits how close drones can get to airports.  I'd suggest you either buy or borrow a Sectional Chart and copy the Legend, which would show you the various types of airspace and other details on charts.  Hope this helps.

If you click on the lowest

If you click on the lowest level chart in SkyVector map display you will see the whole local map and the chart legend is visible.

 

It is centered on a NavAid. The compass rose is not described in the legend but if you look at the center you can see it is part of the navaid.
