If you are tempted to push your luck with the late-season weather, it
helps to have a small area to cover.  I have occasionally had to do this
as late as May in FL, in order to capture particular "event windows",
but its always been a nerve-wracking situation even for a
quarterquad-sized site--the pilots sometimes had to re-attempt for 2-3
days, or at least circle round-n-round to let a gaggle of small clouds
(and their unamusing shadow-puppets) blow away out of the site boundary.

Florida may not have a "leaf-off" season, but there are many trees that
lose their leaves completely even in south Florida, and many that have
much thinner canopies through the winter months.

 

To me the consideration is not only the leaf-off season (there are many
good reasons to capture photography during the leaf-on season).  Cloud
cover and humidity are big factors as well, as is predictability of the
weather.  At least in FL you can count on many days being clear, bright,
and cloud free in the winter.  Come April though, the weather is
unpredictable.  Humidity can start building in the atmosphere making the
imagery unclear.

It has been common practice here in Georgia that you do not fly aerial
photography outside a very limited window of January to March. The
reason given has been to minimize tree cover. Now I was driving through
South Georgia this week and noticing that 80 to 90% of the trees are
pines. I also noticed that by and large the hardwoods, those that are
near structures, are either far enough away not to interfere or are
below the roof lines. That would seem to negate the tree cover issue.
Given that logic, are we, at least in South Georgia, limiting ourselves
for no good reason? My thought is we are.

 

I was wondering what others, especially those involved in Photogrammetry
and tax parcel mapping, might have to say on this issue. I was also
wondering what is the norm in Florida given the lack of a leaf-off
season.
