<div class="moz-cite-prefix">Canada is the second largest country in
the world by area. I understand only too well how inaccessible and
unexplored a land with a harsh cold climate could be as I was born
and grew up in a remote part of Siberia.<br>
<br>
However, the situation changes nowadays. There is now a lot of
innovation in clothing, footwear, and especially in ultra-light
sleeping mats for trekking, sleeping bags, navigation devices,
tents, and even light aluminum tent spikes for snow. This modern
technology allows tourists to access cold areas more or less
safely.<br>
<br>
For example, the documentary film in English "Surviving in the
Siberian Wilderness for 70 Years" <a class="moz-txt-link-freetext" href="https://youtu.be/tt2AYafET68">https://youtu.be/tt2AYafET68</a> was
seen on Youtube more than two and a half million times. It is a
film about a religious family who lived in a forest in a complete
isolation for several decades. And a lot of people hike to this
compound now. I read recently that even a group of school pupils
hiked several hundred kilometers to visit it. <br>
<br>
I mapped several lakes around this compound
<a class="moz-txt-link-freetext" href="http://www.openstreetmap.org/node/3645095042">http://www.openstreetmap.org/node/3645095042</a> via satellite
imagery. A lake could be very useful, as it takes much more fuel
to melt snow than ice. Besides, the water from snow does not
provide minerals to a human body. It could be possible sometimes
to cut through ice till the water of a lake. <br>
<br>
Unfortunately the long footpath leading to this compound is not
visible on satellite photos. If this footpath was mapped it would
be a major security feature for many hikers, and it could also
save some expenses to the rescue service. But it is possible to
map it only via a GPS track, it means an expedition of preferably
7 or more people would have to go along it. Seven or more because
it is a bear land, and no attacks being recorded against parties
of more than seven people.<br>
<br>
I think the remote areas should be mapped carefully, as it is not
possible to ask for directions there. And tourists, sometimes
young students, do venture there more and more. The trekking
equipment for it is readily available via Internet shopping.<br>
<br>
With best regards,<br>

more lakes in Canada than exist in the whole of Europe. Most
are fairly inaccessible and there is little economic incentive
to map each one to a high degree of accuracy. In many
provinces they simply haven't spent the cash to map them
accurately and recently. Some data is forty or more years
old. So digging into the source of the CANVEC data can help
to determine how accurate it is. <br>

We don't have many mappers per square km in Canada and mapping
with a GPS trace doesn't happen at minus 30 for some reason.
If I go back in time to before I imported the CANVEC road data
into Ottawa basically Ottawa OpenStreetMap was incomplete,
inaccurate, over 140 reads had the wrong name when I compared
them to the City of Ottawa map. The City of Ottawa map wasn't
license to copy but I could at least compare the two. Locally
some imports had been done but anywhere an existing road was
in the map an area round the existing road was not imported.
Fine except that roads were not joined up. You couldn't find
a route between two streets in the city.<br>
