<div>The road is a vector, representing the road. It does not
represent the road centreline. It has properties, such as
width and lanes, and sidewalks.<br>

<div>If the boundary *is* the physical feature, then it is not

don't align it.</div>

<div>The NSW/Victorian border has been done entirely along the
riverbank. Much of it by me and a few others after you guys
decided to take your bat & ball. So, I don't believe
this is actually an issue. Do you have any examples of
where this is a concern?</div>
<div><br>
</div>
<div>Tracing the actual border between NSW/Victorian border
was actually quite interesting. You have the gradual
accretion or divulsion to consider, and it is clear the LPI
data is not necessarily aligned with what is current. Most
of the border that I've traced I'd consider to be more
current than the LPI data, and I'd certainly want to thrash
it out before someone started replacing it with yet another
import. We've had so much ugliness in the past with these
imported data sets with no follow up.</div>
<div><br>
</div>
<div>This issue doesn't come up too much with property
boundaries - that are defined independent of the roads. It
does come up with rivers and coastline, and other areas
where the physical feature is what is the boundary.</div>

There are places ..(when I came across one again I'll post a link)
where the road goes down the centre of the boundaries between two
properties. <br>
Being a lazy Ozie I would prefer to tag the road and use that as the
boundary! Save a lot of work, the meaning is fairly clear .. and has
very few impacts on actual use of the map rather than legal
niceties. <br>
<br>
However ... with this data being translated across 'we' get lots of
nodes and detail... with very little 'work'. So it does make it
practical to have the road separate from the boundary. <br>
But if I were entering each node by hand .. you would have the road
forming the boundary (as tagged by me). Someone with more time can
do that detail .. probably less than 10 meters in it. <br>

all property boundaries are not the centreline of

pointed out. So simple do not make boundaries the

Some roads are 'easements' through the property...
<a class="moz-txt-link-freetext" href="http://www.findlaw.com.au/faqs/2296/what-is-an-easement.aspx">http://www.findlaw.com.au/faqs/2296/what-is-an-easement.aspx</a><br>
I tend not to map those .. the presence of the road may indicate it
.. or not as the case may be. Again this is by hand. <br>
<br>
Consider that the amount of things to map is vast, these details can
treble it making getting placing these details on the map a much
longer process. <br>
