Hello,

I have the following problem. I am supposed to make a "picture" with cumulative coverage of radars.

Each radar is defined by Latitude, Longitude and by the range of the radar. The coverage of each radar is a circle. The output should be circles where the color inside the circles is based on how many circles overlap. For example if there is only one circle ( coverage) the color inside the circle is blue, two circles- the color is a bit darker blue- for example. Is there a built in matlab function for something similar?

My script is as follows ( part of it):

[latlim,longlim] = limitm(Z,R);%limits of the map

%% surveillance coverage

ax=axesm('MapProjection','mercator','MapLatLimit',latlim,'MapLonLimit',longlim,'Grid','on','Frame','on',...

'MeridianLabel','on','ParallelLabel','on','LabelFormat','compass','MLineLocation',1,'PLineLocation',1);

load('Hranice');%load State_borders

geoshow(State_borders, 'FaceColor', [1 1 1])

hold on

for i=1:delka_M

dosah=nm2km(M(i,4));

rad = nm2deg(M(i,4));

[lat_surmap,lon_surmap] = scircle1(M(i,1),M(i,2),rad);
