ANALYSIS
Final Suitability
Image for PCS Antenna Site Selection, Burnaby, B.C.
In this
section the final image is analyzed, and final suitable PCS antenna site
locations are chosen.
Choosing
the final candidate locations for antenna placement is difficult.
Should final candidates include
all pixels with a suitablitiy value greater than 200? 215?
Several
thresholds were examined. With a threshold of 170 (in suitability
value), it was found that too many pixels were chosen.
Candidates Selected
Using [Suitability > 170] Threshold.
At this
threshold, the process of selection would still require manual work, selecting
between over 15 or 20 candidates per coverage hole. With a threshold of
215, it was found that some coverage holes had no candidates.
Candidates Selected
Using [Suitability > 200] Threshold.
The final threshold chosen was a
180.
Final Candidate Selection
[Suitability > 180]
Another
factor is candidate size. For placing antennae, it was decided that
the presence of only 1 pixel above the threshold would qualify as a suitable
candidate. It is not nessasary to force candidates to be greater
than say 100 square meters, because of the small footprint that PCS antenna
towers have. 30 square meters is more than enough to accomidate a
tower.
