Having worked on the sales side of a fairly important player in the space,
I can say this is not a trivial exercise. However, if you could give a list
of say the top five to ten players in the space, you might be able to pull
up previous years of revenue info (because a lot of that is on record in
public filings/registrations). From there, you could likely get a ballpark
number.
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. That said, you might
reach out to Black Duck, they do lots of surveys on general open source
stuff. Andrew Ross and Eddie Pickle might also have some ideas.

Hi Andrea,
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

Hi Brian, and thanks for the inspirational overview. I totally
agree with it.
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.
A simple way of getting the number is simply checking the revenue of the
key companies involved in the business.
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.
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);
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.
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...)
Best regards!

Hi Andrea -
like so many good questions looking for a simple answer, there is no
simple answer..
Let's make a thought experiment .. and divide economic acitivity into
three different groups..
Each one could be measured in currency, but I wll argue that only one of
them makes sense..
* in the first case, the market is like a physical market . someone has
eggs to sell, or furniture, or a service like medical service..
a customer pays in currency, and all transactions are recorded
(somehow).. the ecomonic value is the sum of all transactions..
* the second is a market like a legal federation of many marketplaces..
things are available from multiple sources, so prices go up and down..
the prices change for a variety of reasons. But, what if someone gives
something essential, for non-market reasons..
the price may go down.. but what if a machine is invented that make one
million times more of a good or service?
does the price go down ? what if the machine makes something that was
never available before.. is there a price ?
* 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
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,
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
market, to make room for things that are in the market..
what if software can be used to understand these relationships outside
of any market ?
what is the price of this software ..
So, in the first and most simple case.. you could take the sum of
economic activity inside the exchange of currency..
However, on a larger scale, the second and third measures are very
important.. I say that the OpenSource Geospatial
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
others..
good travels in Italy
