Sorry, but I do not understand what the problem is)
You have image - map, ok. We know size of this image(HxW, px -see red text in code), right?
<!-- the image map -->
<layer name="map" url="imagemap.png" keep="true" align="leftbottom" x="16" y="16" width="316" height="222"
handcursor="false"
scalechildren="true"
maskchildren="true"
onclick="closemap();"
>
Well, we draw "invisible" container(zone, mask) for first room inside of this image(imagemap.png),
x="125" y="4" - it's a offset on imagemap.png,
align="lefttop", it's a start point for this offset = top left corner of imagemap, and
width="187" height="115" - size of this container:
<!-- 'rooms' and spots - the 'room' container elements were used for masking the radar -->
<layer name="room1" type="container" align="lefttop" x="125" y="4"
width="187" height="115"
maskchildren="true">
PS: These invisible zones (containers) are only needed if you want to mask the radar beams, inside the walls on the map!
Next, we set the coordinates for each point of the radar(offset and etc. same as container),
inside our invisible container(rectangle mask. This coordinates not inside imagemap.png!):
<layer name="spot1" url="mappoint.png" align="lefttop" edge="center" x="91" y="59" zorder="2" onclick="loadscene(scene__DSC1933_Panorama, null, MERGE, BLEND(1));" />
</layer>
And second zone(container), and coordinates of mappoint inside of this scontainer, for our second room, the same way:
<layer name="room2" type="container" align="lefttop" x="4" y="4" width="117" height="214" maskchildren="true">
<layer name="spot2" url="mappoint.png" align="lefttop" edge="center" x="61" y="104" zorder="2" onclick="loadscene(scene__DSC2041_Panorama, null, MERGE, BLEND(1));" />
</layer>
</layer>
And next, you set start angle for our radar beams for each radar points:
........
<scene name="scene__DSC2041_Panorama" onstart="activatespot(spot2, 90);">
........
To understand this, please read the documentation for a start!

PS: In order to know the coordinates of each zone on your map, open the image in Photoshop(info panel, x,y in pixels ruler) or another editor, and draw outline over the areas that you need, the offset, size and make a note these data!
Good luck!
