project was a re-construction of a 20 year old map that had not been
updated in many years. There were so many changes it was
from new base material and simply use the old map as a guide.
copied the City of Ottawa topo files and the latest orthophotos from
their website an built a base map. The
area is a floodplain of the Rideau river so tracing the contours took
about 3 minutes! The resolution of the photos was good
enough to trace
most of the
detail in the open areas and some of the trail network in the trees. I
completed most of the field work in the fall of 2010 and completed the
final edits just before the first event there last fall.
is a reasonably large park (1.5 sq. Km) but a large middle part of the
map is featureless, marshy woods - dry in the late summer &
but thick with undergrowth and deadfall. Fortunately, there is a good
trail network with boardwalks over the wet areas that
connect the good terrain at the east and west ends. It is an
area for new orienteers, a great place for a BBQ (with beach),
a pretty good area for sprints.
didn't take my own photos of
the park but here are a couple I snitched from Google. It is a very
well managed park with beautiful hiking trails and many supervised
nature programs for students.
is a 1.1 Km snippet from the map that includes most of the relevant
features for review. It's an ISOM standard map with a few special
the boardwalks in
the woods I borrowed the ISSOM (sprint)
paved path symbol. For the docks and floating platforms I used the
light brown (non-traffic) area symbol with the thin bounding line. You
can see that I used the dark brown (traffic) symbol for the parking
dark green pine plantation at the east end is surrounded
lawn - including between the rows. The number of rows is correct but
the gaps in the rows are
just a rough guess. They are slowly growing together. Could it be used
for a maze if it was mapped precisely? Yes, with some out of bounds
ribbon it could be a great maze. Maybe for next summer's meet. : )
In the larger snippet at left you can see more clearly that I pull back
all green areas from the trails for readability. That is a technique
that I use for maps of any scale.
I minimize the use of the "distinct boundary" symbol
it may obscure other features.
Not entirely successful here as
can see in lower wooded area. Probably should have pulled the path away
from the DB symbol at the SE corner just a touch. I could
also have made the
gap between the two well-defined little cedar copses near the trail
more obvious. But then the relative size or position of the copses may
be compromised. Decisions, decisions. The little "boardwalks" are
updating an old map for the regular orienteeing crowd, it was important
for the Centre to have a good map for their "wayfinding" program.
Scores of students from around the region are introduced
to orienteering through this program and the approach taken by
staff is refreshing. Students are taught how to read the map,
understand all the symbols, and how the wayfinding challenge works.
Initially compasses are not used. The students run a score-O course by
only map reading. Using a compass is only introduced to older students
who want to run an intermediate course.
is one of the
novice challenges I helped set up. Now, how do we get these students
out to a regular O-meet?
