Do not account for male/female overlap in available home range area

[GoogleCodeExporter]

When animals attempt to establish home ranges, they cast out the 30 points 
and assess the amount of available area within that polygon. We are only 
considering suitable and unocuppied (by both sexes) as available instead 
of using both suitable-unocuppied and suitable-occupied only by the other 
sex as areas that are available (see attached).

I am going to add more logging.  I just reviewed the code and it should be 
accounting
for available and unoccupied and available and occupied by the other sex.  I do 
not
think I made any changes to that part and we were overlapping before with males 
and
females.  So I am guessing it probably has something do with the way I am 
calculating
the area, not the polygons I am calculating

Bob,
I would be very surprised if the polygon area calculation was the problem. When 
I 
calculated the area of the suitable-unoccupied polygon only, it perfectly 
matched 
the area in the home range log as available. My guess would be the issue arose 
when 
we made the change to the dissolve by multiple fields where we kept occupied 
male 
and occupied female instead of just using a clever trick to assign a single 
field as 
available. Hopefully the extra logging will help us sort this out.

I think this was handled while down in Perdue the weekend of Aug 1/2

I believe this was fixed by dissolving area based on suitability and 
occupied-same-
sex.
