<p>I know lots of companies are working around with slide decks that say things like "Total Size of Geospatial Market" with a big pie chart and a tiny FOSS slice jumping out but I feel like it's more of a marketing clip art exercise than a result of actual number crunching.

Hi Andrea,<br>
<br>
Not quite the same question, but an easier metric to measure, is the
"estimated cost of software to develop", using David Wheeler's
method for evaluating the cost of Linux to develop<br>

<div>Hi Brian, and thanks for the inspirational
overview. I totally agree with it.<br>
<br>
</div>
But if I go back with this to my colleague (I
won't meet him at the cafe after
close-of-business today because I'm travelling,
but tomorrow might well be), he will claim that
this is too much of a quasi-philosophical
explanation.<br>
<br>
</div>
A simple way of getting the number is simply
checking the revenue of the key companies
involved in the business.<br>
<br>
</div>
The next "quantum leap" in innovation might be round
the corner and completely change our paradigms for
estimating the size of a market, but until this
happens, if we are assigning a value to it, we are
making a bet.<br>
<br>
</div>
The "third level" you mention is what my colleague
calls "ecosystem services". Interestingly, their value
can be estimated as well (I have started to work a few
years ago on one of these cases);<br>
<br>
</div>
but for the time being, I will stick to "level 1",
considering the thread open for a couple of days, should
any other folk wish to drop a line.<br>
<br>
</div>
Thanks also for the "good travels" in Italy...in fact I am
an Italian citizen and a resident, but I travel quite a
lot up and down "The boot", as we call it (today towards
the AC/DC gig in Imola...)<br>
<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi Andrea
-<br>
<br>
like so many good questions
looking for a simple answer, there
is no simple answer..<br>
Let's make a "thought experiment"
.. and divide economic acitivity
into three different groups..<br>
Each one could be measured in
currency, but I wll argue that
only one of them makes sense..<br>
<br>
* in the first case, the market
is like a physical market .
someone has eggs to sell, or
furniture, or a service like
medical service..<br>
a customer pays in currency, and
all transactions are recorded
(somehow).. the ecomonic value is
the sum of all transactions..<br>
<br>
* the second is a market like a
legal federation of many
marketplaces..<br>
things are available from multiple
sources, so prices go up and
down..<br>
the prices change for a variety of
reasons. But, what if someone
"gives" something essential, for
non-market reasons..<br>
the price may go down.. but what
if a machine is invented that make
one million times more of a good
or service?<br>
does the price go down ? what if
the machine makes something that
was never available before.. is
there a price ?<br>
<br>
* the third is the natural world
we live in.. a unique collection
of clear air, clean water, things
to eat and places to live and<br>
make babies.. what is the "price"
of clean water ? does it go up or
down.. what is the "price" of a
rhinocerous or an elephant,<br>
that is a living being not in the
human market at all .. what if the
actions of the market kills or
poison things that are not in the<br>
market, to make room for things
that are in the market..<br>
<br>
what if software can be used to
understand these relationships
outside of any market ?<br>
what is the "price" of this
software ..<br>
<br>
So, in the first and most simple
case.. you could take the sum of
economic activity inside the
exchange of currency..<br>
However, on a larger scale, the
second and third measures are very
important.. I say that the
OpenSource Geospatial<br>
software worlds are very much in
all of those.. so any number you
count in the first one will be a
poor measure of the<br>
others..<br>
<br>
good travels in Italy<br>
