The Alberta Township System can be a pain to relate to
geographic coordinates. While it is a survey system (or land
parcel definition system) defined by physical monuments placed on
the ground, it is often just "estimated" using the original rules
used in laying out the monuments back in the late 1800s.<br>
<br>
The official source of the data is
<a class="moz-txt-link-freetext" href="http://www.altalis.com/products/property/ats.html">http://www.altalis.com/products/property/ats.html</a>. While the
polygon file is provided at a cost ($1000), a text file of survey
corners is available for free. But joining the corners into
polygons is not for the faint of heart.<br>
<br>
If all you want to do is check general correctness of your
data, and not the positional accuracy of your locations, you could
use the federal government's approximation of the township system
available at <br>

This is a 1gb download with several Canadian reference
systems, including the township polygon shapes down to the section
level (unfortunately not down to the quarter section level). The
files you would be interested in are named<br>
\DATA\RFGRD\SHP\dls_w456_n83_polygon.* in the zip file.<br>

but none of the sources listed there really help. The offered
ressources do not provide a layer as far as I skipped through
it. A layer would be just fine, but all I came up to was this
converter and a very poor Township Grid, available here: <br>

Still looking for a good solution that does not force me to do
wild guesses at sections when comparing wtih satellite
imagery.<br>

<pre wrap="">HI Michael,
I don't suppose it's available as a layer already? There seems to be quite a
few resources here
