| May 17, 2012 at 15:11 | comment | added | Bavin | @whuber: I will add a little clarity: I will attach a sample picture of what i need!(Posted above)The red lines are irrelevant to my present project though these will come in at a later stage. Take for example that single "flower" with all lines drawn towards it.The industry code word for each petal is sector.It represents a tower mounted with 3 antennas(sectors) at 0, 120, 260 degrees. My first hurdle is how i can draw these polygons of this shape from an excel/csv containing sector name, sector azimuth, sector latitude & sector longitude. | |

In step (1) you don't necessarily use the radius of the polygonal representations of the sectors: you use any desired query distance. In step (2), intersection of sectors guarantees that they are facing. | |

| May 16, 2012 at 21:38 | comment | added | whuber | Once you have completed step 2, would it not suffice in step 3 simply to (1) find all towers within the desired distance of a selected sector and (2) among those towers, retain those whose sector polygons intersect the selected sector polygon? | |
