circular sector with polygons

[Radicz]

Hi everyone, sorry for my English.

I need help to create circular sector with polygons. I found this
http://pastebin.com/f3b2cdea8, but I have no idea how it works or how
to integrate it into my cource code. Could someone please advise me?
Thanks for any answers

My source code

var PoleBodu = [
['Spartakiádní', 50.68504754096478,
13.990276157855988, ..........,null],
['Dukelských hrdinů', 50.683881737055, 13.998518586158752,.......,
null]
];

function initialize()
{
var Nastaveni = {
zoom: 12,
center: new google.maps.LatLng(50.68681982238762,
14.000144215759285),
mapTypeId: google.maps.MapTypeId.ROADMAP
}

map = new google.maps.Map(document.getElementById("mapa"),
Nastaveni);
InfoOkno = new google.maps.InfoWindow({maxWidth:350});

for (var i = 0; i < PoleBodu.length; i++)
{
VytvorBody(PoleBodu[i]);
}
}


function VytvorBody(PoleBod)
{
var icona = new google.maps.MarkerImage(PoleBod[5], new
google.maps.Size(39, 47), new google.maps.Point(0,0), new
google.maps.Point(0, 33));
var stin = new google.maps.MarkerImage(PoleBod[6], new
google.maps.Size(35, 35), new google.maps.Point(0,0), new
google.maps.Point(-5, 27));
var klikarena = {coord: [0,0,40,40],type: 'rect'};

var pozice = new google.maps.LatLng(PoleBod[1], PoleBod[2]);
var bod = new google.maps.Marker({
position: pozice,
map: map,
name: PoleBod[0],
shadow: stin,
/*icon: icona, */
shape: klikarena,
zIndex: PoleBod[3]
});

PoleBod[7] = bod;

google.maps.event.addListener(bod, 'click', function()
{
InfoOkno.close();
VytvorInfoOkno(InfoOkno, map, this, PoleBod);
$("#tabs").tabs();
OzariProstor(2000, map, bod, PoleBod);
});

}

function OzariProstor(radius, map, bod) //funkce tvorici polygon
{
if(!bod.highlighted)
{
bod.highlighted = true;
var circle = new google.maps.Circle({
map: map,
radius: radius,
fillColor: "#B43116",
strokeWeight:2,
strokeColor:"#7D0A05"
});
circle.bindTo('center', bod, 'position');
}
}

function VytvorInfoOkno(InfoOkno, where, which, PoleBod)
{
if (PoleBod[7] == which )
{
InfoOkno.setContent(PoleBod[4]);
InfoOkno.open(where, which);
}
}

I'm not sure what you are trying to accomplish. Please post a link to
your map rather than code:

I trying to make a map for the Internet provider and I want to click
on Mark show coverage from the antenna. Omnidirectional antennas are
easy, because it is an ordinary circle. To directional antennas but I
need a circular sector. Unfortunately, I do not know how to do it.

What information do you have to work with?
To define a circle, you'd have the centre point (mast) and a radius
(range) I guess.
What do you have to work out your sectors ; radius, centre , and ...?

[Radicz]

I'm sorry, I hope I translated correctly your answer.

"> What do you have to work out your sectors ; radius, centre ,

and ...?" I think the direction where the antenna shows.
I know what the coordinates of the antenna is located. I know its
broadcasting angle and know which direction the antenna points. I do
not know if it's enough to create a circular sector

What do you mean by a circular sector? A pie shape? If I recall
correctly directional antennas have an asymetrical dumbell shape for
their coverage. If that is what you need, you will need to dig up an
equation for it.

[Radicz]

Yes I think it is a pie shape. Coverage is to be informational only.
The equation for the creation of the sector should be here

[Radicz]

This site has it. Clicking on any mark displayed Sector

Did you see the green polyline on this example from my first post:
http://www.geocodezip.com/v3_polyline_example_arc.html

I think that does what you want. You can combine the pieces into a
polygon.

It is the perfect thank you very much

Hi again everyone.
I have a little problem with the circle pie. When you try to make a
pie down. It does this http://178.77.202.130/pokus/ . Could someone
help me please?

Swap your start and end points

[Radicz]

Unfortunately it did not work

[geoco...@gmail.com]

Wasn't quite that simple. The algorithm didn't handle the -180 point
well.
