<br><font size=2 face="sans-serif">Hello Mike,</font>
<br>
<br><font size=2 face="sans-serif">Interesting proposal.</font>
<br>
<br><font size=2 face="sans-serif">Are you talking about:</font>
<br>
<br><font size=2 face="sans-serif">- true 3D as in non-uniform objects,
e.g. geological models in 3D space where an end user may want to do say
solid modelling and conduct 3D operations such as subracting one object
from another object (as in mine modelling).</font>
<br>
<br><font size=2 face="sans-serif">- pseudo 3D as in a Digital Elevation
Model where you can only model orthogonal surfaces which preclude things
such as caves or cliffs with overhangs etc.</font>
<br>

<br><font size=2><tt>Dear Friends, ( please forgive cross posting )<br>
<br>
I've been thinking a lot about 3D GIS lately, about interoperability of<br>
3D objects in real world - virtual worlds like Google earth, Microsoft-<br>
virtual earth, NASA wwind, ESRI ARCglobe, companies like Autodesk have<br>
large legacy 3D GIS &CAD systems still moving forward, and no
doubt<br>
someone like Linden Labs will launch a 3d social apps in a real world -<br>
virtual world.. based on geo coordinates instead of 2nd life's random<br>
geography, and even mobile 3Dgis is quickly showing glimmers of<br>
promise: mobile augmented reality developers will likely build
a<br>
geocoded 3D frameworks to hang links on... for services like nokia's<br>
MARA prototype (http://www.technologyreview.com/Infotech/18291/) ... and<br>
a consensus 3D geoweb like GEON ( http://www.geongrid.org/about.html)<br>
will also be the basis for the worldwide sensorweb, eg. for<br>
trans-disciplinary problem solving like macro-ecology, climate models,<br>
zoonautic, ( animal born disease) emergency response, &&<br>
<br>
Will we have multiple 3D geowebs? beyond harmonized 2D geodata and<br>
geocoded hypermedia, will 3D data and media producers and service<br>
operators have to produce and manage multiple frameworks ( including<br>
places, buildings, things - people& avatars ) for each or these<br>
environments?<br>
<br>
So, following digital earth, champion, Tim Foresman's lead -
(As<br>
Director of Digtal Earth programs for NASA working for vp gore, Tim lead<br>
the first DERM - A reference model in the Federal Geospatial
Data<br>
Committee and ISO communities in collaboration with the original NASA<br>
led Interagency Working Group on Digital Earth. That work is now
off<br>
on a dusty shelf, out of date, given the future requirements.)<br>
<br>
I'll be leading sessions at Where2.0<br>
(http://conferences.oreillynet.com/where2007/) and ISDE5<br>
(http://www.isde5.org/) to raise questions leading to re-starting<br>
considering of a consensus reference specification, for a 3D geoweb - a<br>
a standard Digital Earth. google, no doubt, sees kml as the
answer to<br>
these questions, and MS is, no doubt brewing up their own too, clearly<br>
the big guys are going to duke it out from very proprietary<br>
perspectives, and it's still not clear that the US gov, OGC, W3C, OR<br>
SIGGRAPH communities like x3D focusing on vrml, offers the integrated<br>
perspective of the participatoryGIS, FOSS4G and digital graphic arts<br>
communities, here, capability to develop detailed optimum requirements<br>
from wide perspectives:<br>
<br>
Let's start again considering, as communities, a meta level layered<br>
architectural description for unified earth and geo-related computing,<br>
refining a model including the following topics ( and others) into an<br>
ideally coherent and rigorous framework for optimally sharing and using<br>
data across all web, geospatial and scientific contexts:<br>
<br>
* geodesics, where experts are still refining descriptions of the shape<br>
of the earth, and where new coordinate systems are argued.<br>
* sensor data generation and labelling<br>
* geodata and hypermedia coding/decoding/transcoding<br>
* open source networked geodata -libraries and feeds- of raw sensor<br>
data, streaming media, tiles, 3D objects , 2Dvectors, polygons, points,<br>
text, etc.)<br>
* geo metadata models - formal ontologies, logical description, as<br>
frameworks for mining informal users' tag systems<br>
* geo server and middleware models for efficient saving, searching, and<br>
sharing of all kinds of geodata<br>
* sensemanking inference and other spatial intelligence<br>
* rendering software for combining many sources of geodata into unified<br>
useful views for many kinds of interaction<br>
* user software/ sharing/saving/serving/searching/rendering<br>
* human interaction systems, avatars and social nets, gis,
mobile gis,<br>
3Digs, geoaudio, augmented reality, haptics<br>
* autonomous sensor networks processing geodata.<br>
* meta scale geosciences exploring large transdiscipline problem spaces<br>
like planetary meteorology, large scale ecosystem modeling,<br>
human-ecosystem interaction models, large scale, emergency response,...<br>
<br>
These are just penciled place holder layers of a hypothetical reference<br>
model - that will need to be refined by the appropriate communities.<br>
<br>
I have no idea how to organize a coherent dialog between the e-mail<br>
list communities cc'd here. right now, maybe somewhat loosely<br>
connected dialog will be fine. later perhaps starting at where2.0 and<br>
ISDE5, maybe some kind of 3D geoweb wiki communities will coalesce to<br>
start organizing these consensus interoperable models.<br>
<br>
See you in San Jose and Berkeley!!<br>
