    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>
                                      <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>
