Katleen Janssen and Danny Vandenbroucke; investigate the issues

internal report for the Nature SDIplus project and a scientific paper will
follow the report soon. I will announce it on the [geodata] list as soon
the text will be released (report) or published (paper).</SPAN></DIV>

<P style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><FONT size=3
face="Comic Sans MS">Here at the City we use the same system for internal and
external access, and the extra costs have thus far been marginal to allowing
access. There are some potential problems with this though in the

negatively and cause a rethink of the publishing.</FONT> </P><BR>
<P style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><FONT size=3
face="Comic Sans MS">One big business need that this solves for us, is in being
able to see other regional data owners data since they do the same as we do in
the publishing department so we can see each others datasets and not have to
worry about keeping a local set available and up to date. While this is
not happening across the board with all regional data owners, more and more are
coming online all the time.</FONT> </P><BR>
<P style="MARGIN-TOP: 0px; MARGIN-BOTTOM: 0px"><FONT size=3
face="Comic Sans MS">A bigger concern is how to share data that is sensitive in
nature between jurisdictions, that each agency should have access to but the
general public shouldn't. I know this thread is aimed at the public use,
but I would suggest that there are a middle class/level of user, where the data
usage needs to be tracked. Not exactly closed off from viewing, but in
many cases for security reasons, the usage needs to be tracked in some form.
This is something that is continuously being wrestled with here.</FONT>

geodata@lists.osgeo.org<BR>> Subject: RE: [Geodata] What is the value of free

the old Roman wisdom says, that the item is worth as much as<BR>> customer
wants to pay for it. (-; So I think your first suggestion is<BR>> close to
the objective. (-:<BR>><BR>> For raster it could apply easily, however for
vector... these maybe<BR>> difficult to use, as even the same themes of the
same geometric <BR>> quality<BR>> (scale) have sometimes extended
attributes, which acquisition in the<BR>> real world is maybe expensive - in
this case I would add total cost of<BR>> the generation of additional
information. A good example would be<BR>> cadaster parcels. The geometry
itself is usually accompanied with plot<BR>> number, but when it comes with
additional attributes of owner and 4eg.<BR>> commercial value
- well, that's completely different story, because <BR>>
you<BR>> have to finanse the valuation of the parcels and
building/connection <BR>> of<BR>> the owner database. Other examlpe
could be soil or other environmental<BR>> maps - where number of physical or
chemical attributes may grow into<BR>> huge databases. So cost of the
geometry itself may be one thing and <BR>> the<BR>> cost of the
attributes - other.<BR>><BR>> Best regards:<BR>> Raf<BR>><BR>>

Subject: [Geodata] What is the value of free data?<BR>><BR>> It is great
to make geodata free. However, we could get more of it if<BR>> we
could quantify the value of that data.<BR>> We need to justify the business
case.<BR>><BR>> Interestingly, for opensource software projects, you can
compute the<BR>> potential cost of developing that software.<BR>> This is
an approximation of the value of that code [but not the value<BR>> that is
enabled by the code] So I am looking for a similar and still<BR>> imperfect
metric.<BR>><BR>> Any suggestion?<BR>><BR>> Cost of similar
commercial imagery?<BR>> Economic value of imaged area?<BR>> Potential
damage assessment (disaster)?<BR>> Scientific value of
imagery?<BR>><BR>> How do we estimate this?<BR>><BR>>
