In defense of the NSW DCS Base Map? Some have criticized the DCS
Base Map .. a response below. <br>
</p>
<p style="line-height: 100%; margin-bottom: 0cm"><br>
</p>
<p style="line-height: 100%; margin-bottom: 0cm">“We don’t want
OSM to be a copy of the DCS Base Map”? Umm OSM has capability of
far more than the DSC Base Map e.g. pubs, petrol stations, farm
fields, vineyards etc. So it should be far more than the DCS Base
Map. Where OSM is missing stuff that is in the DCS Base Map why
should it not be copied? That is a gain for OSM. </p>
<p style="line-height: 100%; margin-bottom: 0cm">“The DCS Base Map
is out of date”? So is the OSM data! I don’t see that point of
this ‘argument’ at all. If something in OSM is ‘out of date’
then correct it. If something is missing from OSM but is in the
DCS
Base Map then copy it. Those who know it is out of date can
correct
it, arguing that it should not be added because ‘it may be out of
date’ could be applied to all sources other than those sighted in
the last day. Should any data that ‘may be out of date’ be
rejected? I have found some things in the DCS Base Map to be more
upto date than the DCS imagery having to resort to Maxar to
confirm
the existence of the objects. So the DCS Base Map maybe ‘out of
date’ for some things but more ‘upto date’ for other things.
Such are the joys of our changing world. </p>

<p style="line-height: 100%; margin-bottom: 0cm">“On the ground
truth” Some take the view that they have been there and seen X.
Ok,
the DCS Base Map says Y.. Humm. Where this is some land form or
land
cover I take it the mapper involved has more expertise than those
that contribute to the DCS Base Map to determine that land form or
land cover. I would not put myself in that category. As an example
the ability to determine an area is an arid wetland, I have no
expertise to determined that and would take DCS Base Map as more
authoritative than my poor observations. </p>

<p style="line-height: 100%; margin-bottom: 0cm">---------------</p>
<p style="line-height: 100%; margin-bottom: 0cm">Me? </p>
<p style="line-height: 100%; margin-bottom: 0cm">I have added
libraries (those facilities that lend books) from the DCS Base Map
..
using a list from a copyright source to direct me to the area and
then searching the DCS Base Map for it. The location and name
comes
from the DCS Base Map not the copyright source. This is not all
the
libraries as some are ‘private’ e.g. schools. But it has got at
least most of the public ones into OSM. I call that a win for OSM.
</p>
<p style="line-height: 100%; margin-bottom: 0cm"><br>
</p>
<p style="line-height: 100%; margin-bottom: 0cm">Mangroves. These
are well defined by the DCS Base Map. I have been
questioned as to how reliable they are .. well on 5 that I gone to
those all appear to be accurate .. and others can be seen on
imagery.
So I am quite confident that these can be transferred from the DCS
Base Map into OSM. </p>
<p style="line-height: 100%; margin-bottom: 0cm"><br>
</p>
<p style="line-height: 100%; margin-bottom: 0cm">And I have copied
other stuff, missing in OSM, from the DCS Base Map. There is a lot
of
it! I plan on continuing to do so. The DCS Base Map is a great
resource that we should use. I have even found errors in OSM from
the
DCS Base Map. </p>
