BB1724
: El ADNaCS
Wednesday
12th July 2017
Due
to it currently still being under development,
you are probably not aware that ADNaCS is
software for calculating navigation corrections
for complex terrain. It is being developed
for the Earth
Observing Laboratory.

You
are also probably not aware that BOOTboys
were to undertake a field test today, but stranger things
have happened and perhaps such is our renown in unexpected
circles.
Our
chosen route was the Scandale circuit clockwise. I
have only done it anti-clockwise previously.
As
we set off past the Golden Rule in Ambleside, it was
a glorious morning, quite possibly the best fell walking
day of the year.
We
had no navigational difficulties climbing up to Low
Pike then High Pike.
In fact we were going so
well that we decided to add in firstly Dove Crag and
then Little Hart Crag where Stan had an argument with
a man passing in the opposite direction as to who had
the oldest pair of fell running shoes. Robin and
I agreed that Stan won feet down with his description
of a pair he had bought in 1832 or something like that.
The
required complex terrain was encountered after we passed
the Scandale col and began to climb diagonally to Middle
Dodd. Navigation was difficult and the terrain
was indeed a complex jumble of very steep grass, crags
and large boulder deposits. It was challenging
to find the required path. Despite several attempted
direct visualisations of the correction factor application,
we none-the-less had to pioneer a route that led under
and round these obstacles. Eventually we used
the old fashioned manual method of heading directly
up the hill. The path from Red Screes was met
and no further navigational corrections were required.
Having
reached Middle Dodd and enjoyed the views down to Brotherswater
and beyond, we turned round and followed the path to
the summit of Red Screes and the precipitous drop to
the Kirkstone Inn.
Unfortunately by this time the sun
was frequently obscured by cloud. This, plus the
desire to get out of the reach of the midges, caused
us to move on to lower ground before taking lunch.
A
chilly wind was starting to blow. Had
the EOL asked us to participate in their field study
experiment to study windflow over complex mountain terrain,
we probably would have been able to help them.
However
this, the most recent of EOL's field studies, the Perdigão
Project, is in Portugal at Vale Do Cobrão, near
the Spanish border.
Over
the border, in Spain, the local name for the software
under test is, presumably, El ADNaCS.

Whereas
the ground on the western side of the Scandale valley
had been surprisingly dry, this was not the case on
the eastern descent. There was quite a lot of
bogginess to navigate but that too was not part of the
ADNaCS study.
Two
cows guarded the view over to the Crinkles, Bowfell
and the Langdales.
Finally
we reached Ambleside and more importantly, the Golden
Rule. Here we had a debrief on our observational
findings. We had completed the reverse direction
circuit. It was then that we realised to our utter
astonishment that Scandale in reverse spells El
ADNaCS
! And vice-versa!
What a crazy coincidence this is.

weekly offerings continue to delight this fell lover.
As a mountain and sailing instructor at Brathay
Hall (1964 -67) many of your routes are revisited on
my iPad! Oh, what joy it is to share those beautiful
places once again.
Don:
Thanks, Chris, although it ain't me that's adventurous,
it's Stan. He was having to motivaate this wimp
to get across that dodgy terrain!

Thanks, John. It would nice if the Comitibus could be
scheduled automatically! For the benefit of those
who are unaware, Natland is the village where I live.
